The chart above identifies in general terms each of the standard WKM trims.
• Valves ordered with Worm Gears (WGA) are shipped with gears installed, but handwheels are not installed
(shipped separately)
• Valves ordered Less Gear (LG) with gear mounting plate installed (for actuation by others)
The trim charts provide more specific application details including availability of fire-tested materials. Please contact Cameron for
information concerning availability of trims other than those listed or for any additional information concerning the choice or
guidance for application of the trims listed. NACE MR0175/ISO 15156 Compliance – Materials of construction shall be in
compliance with the pre-qualified material requirements specified by NACE MR0175/ISO 15156. According to NACE MR0175/
ISO 15156, it is the manufacturer’s responsibility for meeting metallurgical requirements and the customer and user responsibility
to ensure that a material will be satisfactory in the intended environment. When given the application requirements
(environment) by the customer/user, Cameron can make technical recommendations in accordance with NACE MR0175/ISO
15156, but that in no way certifies or warrants the product or materials for the application.

The above values are new valve torque values, where P is the maximum operating pressure (psig) of the valve.
The above torque values do not contain service factors.
Soaking effects and/or particle matter in the valve may cause an increase in the torque.
For intermediate pressure use the torque expressions for the stated pressure range.
For example, an intermediate pressure of 1000 psig uses the torque equations that correspond to the 751 to 1500 psig pressure range.
The re-seat torque is taken as 0.75 times the break torque.
For power operation, multiply all of the above values by a factor of 1.25 or customer specified factor whichever is larger.
For operating temperatures between -20° F to -50° F (-29° C to -46° C), multiply these values by 1.20.
Actuator selection should be made on customer experience and appropriate service factors.
