Worm Gear Operators

Cameron’s DT Series worm gear operators are designed for use with

valves and dampers, as well as most other quarter-turn applications

requiring a self-locking mechanism. Our flexible manufacturing

process allows us to offer both standard construction and custom

configurations for customer-specific applications.

Standard operators are available with various mounting interface

dimensions. Custom-machined gears come with bores and bolt

holes for direct mounting to the valve. Standard materials are cast

gray or ductile iron, but the line also offers a varied selection of

alternate materials to meet customer application requirements.

For extremely corrosive applications, operators with external

components constructed of cast CF-8M stainless steel are available.

These operators are completely sealed and are ideal for applications

such as brewing, food processing, leaching operations, offshore

platforms and pulp and paper plants. Gear operators with stainless

steel internal parts also are available.

Bevel Gear Operators

The BG Series bevel gear operators provide smooth, even torque

transmission for thrust and non-thrust applications such as gate,

knife gate, pinch, sluice gate or globe valves. This line of operators

also can be used in almost any multi-turn, right-angle application

requiring mechanical advantage.

Manual Overrides

Cameron’s DYNATORQUE automated valve manual overrides are used with

pneumatic, hydraulic and back-drivable electric actuators. These products

are sandwich mounted as part of an automated valve package to provide

manual operation of the automated valve if a loss of plant air supply,

power gas, hydraulic fluid power or electricity occurs.

Valve Locking Devices

The DYNATORQUE D-Lock automated valve locking device is used with

automated valves (pneumatic, hydraulic or electric) that require lock-out

capability to prevent valve rotation. This feature is ideal for applications

such as maintenance shutdowns, when the valve must remain in a

locked position even if an actuator is unintentionally engaged.

FEATURES

• Holds valve in either open or closed position while compensating for

hysteresis and machining tolerances (select models provide both open

and closed locking)

• Ideal for torque-seated valves such as triple offset buttery valves

• Applicable for almost any rotating device

How It Works

The D-Stop device has two internal cams. During normal valve

operation, the D-Stop device is disengaged and the actuator is free

to stroke the valve on demand. When the partial-stroke test is to be

performed, the stainless steel engagement key is inserted into the

D-Stop key socket.

A safety feature designed into the device forces an intentional,

two-handed operation in order to engage the D-Stop device. When

the safety release mechanism is pulled, the engagement cam is free

to rotate 90 degrees counterclockwise. Once the key is turned, it is

locked into the device and the engagement cam rotates. The device

is now engaged (see illustration below).

At this point, when the valve actuator is sent to the test position,

the drive cam that is attached to the actuator through the drive

coupling rotates until it comes into contact with the engagement

cam, normally 20 degrees (this is a specifiable value). Metal-to-

metal safety prevents the actuator from rotating past the set point.

D-Stop Partial-Stroke Test Device

The DYNATORQUE D-Stop device is one of the world’s premier

mechanical devices for partial-stroke testing of installed critical service

valves, such as emergency shutdown valves (ESDVs), while the valves

are flowing process fluids and full-stroke valve testing is not practical.

D-Stop devices are built for both large and small

valves. This DT4000 D-Stop will t between a large

pneumatic actuator and a 36” 600# ball valve

installed on an offshore platform.

The picture at the right shows the same DT1000 D-Stop, but with the device

now engaged. Standard travel is 20 degrees, but this value can be specified

to your unique requirements.

The photo to the left shows the D-Stop

device fully engaged with metal-to-metal

safety, preventing the valve from closing

during the test procedure.

The photo to the left is a DT1000 D-Stop in

factory assembly with the cover removed.

Note the D-Stop is not in the engaged position.

Cameron manufactures D-Stop devices up to

4,000,000 lb-in (451,939 N·m) capability.

D-Stop devices are modular: specify

local key operated or remote operated

with or without optional limit switches

to indicate “on-test /off-test.”

BENEFITS OF CAMERON’S DYNATORQUE D-STOP DEVICE

SIMPLE When it comes to testing systems, the

temptation is to take what already might be a

sophisticated automated valve system package and

make it even more complex by adding controls.

With Cameron’s DYNATORQUE D-Stop device, it is

not necessary to integrate into the control loop or

add ancillary controls, as is the case with electric

systems. It’s simple.

ECONOMICAL

The basic cost of a D-Stop device,

depending on the torque requirement, is more

economical than an electric or controls-driven

system. Instrumentation personnel and software

programmers are not required to install the D-Stop

device, lowering installation costs. Commissioning

or routine calibration of controls is not required

because there aren’t any. Most process plants have

qualified in-house mechanics or valve automation

centers nearby, and since there are no additional

controls required, installation cost savings can

be substantial.

TRUE SAFETY SYSTEM TESTS Because the D-Stop

device requires no extraneous controls when the

valve is tested, all the actual SIS components, controls

and elements used in an ESD or safety valve will be

activated. You have information about the exact

controls that will be relied upon to protect your plant

and personnel.

BUILT FOR A DEMANDING, INDUSTRIAL ENVIRONMENT

The D-Stop device is vibration resistant. It is externally

corrosion protected with coatings and independently

certified to IP 67 to prevent water ingress. Stainless

steel trim is used for keys, shafts and sockets. The

D-Stop device is permanently lubricated, factory sealed

and requires no routine maintenance.

SIL CAPABLE The D-Stop device has been reviewed

by an independent third party and found to be SIL

capable. Email us at info-dyt@c-a-m.com for a copy

of our Failure Modes, Effects and Diagnostics Analysis

(FMEDA) for information such as Probability of Failure

on Demand (PDFavg) necessary to calculate SIL values

for your application.

Actuator-to-Valve Direct Interface

The complete DYNATORQUE line of automated valve accessory products – manual

overrides, partial-stroke test devices and valve locking devices – are suitable for use with

all styles of quarter-turn automated valve and damper packages. Actuators

can be powered by pneumatics, hydraulic oil or electric motors.

Common to all of these products is the direct interface mounting

concept; that is, the DYNATORQUE product fits between the

actuator and the valve (see below for an example of the

DYNATORQUE

D-Stop). The actuator drives the valve open and closed

by means of a driver that connects the actuator to the valve stem. The driver and the

top and bottom of the device will be machined to custom fit your valve and actuator

combination or DYNATORQUE standard dimensions or ISO 5211 – you decide.

Cameron’s DYNATORQUE automated valve accessories can be provided as a

component of a new automated valve or it can be field-retrofit to an existing

valve/actuator package. Just give us the dimensions and we will make it.

Spur and Miter Gears

Spur and miter gears are used in applications requiring a

non-self locking mechanical advantage or where a change

in input drive orientation is required. Both devices can be

used as add-on features to our worm and bevel

gears or can be purchased as standalone products.

SPUR GEAR FEATURES MITER GEAR FEATURES

• Heavy-duty iron and steel components

• Used with worm gear and bevel gear operators to allow

for reduction in handwheel sizing and handwheel rim pull

effort

• May be used independent of worm and bevel gears

with small non-rising stem gate and globe valves and

other non-self locking applications that require torque

multiplication. When used with small electric motor

operators, it provides a low-ratio, non-self locking

torque multiplier

• Heavy-duty iron and steel components

• For use as a close-coupled gearbox that changes

handwheel input shaft direction on worm and bevel gears

• May be used to change shaft direction (90 degrees) on

any rotating device with compatible torque values and

interface dimensions

Spur Gear Miter Gear

Handwheels

A comprehensive line of handwheels is offered in 6”

through 48” diameters. Standard handwheels are

designed for use with our gear operators, and many

are available in either recessed or flat versions.

FEATURES

• 6” to 10” handwheels are recessed, cast duct iron

•

12” to 18” handwheels are manufactured from tubing

and are available in standard recessed and optional

at congurations, as well as in stainless steel

• Tubular handwheels are epoxy powder coated

• Cast handwheels are e-coated

• Additional diameters and interface machining

available

FEATURES Chainwheel Adapters

DYNATORQUE chainwheels are available

for applications where valve and operator

combinations are in locations

where direct handwheel

operation is not possible.

• Allows mounting of the chainwheel directly to the operator-input

shaft rather than the rim of a handwheel

• Design reduces the amount of cantilever load on the operator-

input shaft and eliminates the need for a handwheel

• Standard chainwheel construction is cast iron with many

optional materials available

• Fabricated of 1018 steel

FEATURES

Ground Position Indicators

The remote ground position indicators

are mechanical devices used to visually

indicate the position of a buried or

otherwise hidden valve. For example,

when a valve and gear are installed in

a buried service application, it may be

difficult (or impossible) to know if the

valve is open or closed.

• Capable of exceeding 30,000 turns

• Ground-level window indicates valve open or closed

in bold red lettering

• Optional limit switches indicate valve position to

operator in a remote location

• GPIS offers sealed version

• Optional 2” square operating nuts, extension stems

and couplings

Memory Stop/Multi-Turn Worm Gears

A special traveling-nut module is added to the standard

DYNATORQUE worm gear, providing a highly adjustable

memory stop. Ideal for use when the driven device is used

for flow control and must

always be opened or

closed to the same

exact position.

FEATURES

• Highly adjustable travel stops

• “Memory stop” device suitable for valves

and dampers

• Traveling nut module allows repeatable

valve travel to the predestinated set-point
