LEDEEN Valve Control Board for
Pneumatic Actuators
2
Since 1946, Cameron’s LEDEEN® brand has been providing
engineering and technical expertise for valve actuators and
control systems. Continuing this legacy, Cameron has
designed a standard valve control board (VCB) for
pneumatic actuators.
Designed using in-field, real world problem solving and
keeping serviceability in mind, this VCB offers one of the
highest levels of reliability and safety on the market today.
The system has been developed to provide a turnkey
control panel for the most common logics used for on/off
valves in oil and gas applications. The LEDEEN VCB for
pneumatic actuators is capable of a variety of operations,
including increasing flow capacities and suite operation
requests on stroking time on a wide range of actuators.
This innovative product is highly customizable, allowing for
a flexible layout with a variety of options, including stop,
check, relief, and flow regulating valves. It offers one of the
easiest retrofits in the industry, maintaining brand-neutrality
and certification quality.

Panel: Control system components are mounted on a SS 316 panel complete with a sunshade
Dimensions: Panel has a very compact design – overall dimensions are 18” x 16” x 10” (450 mm x 400 mm x
250 mm) for fail-open and fail-closed schematics for spring return actuators and 22” x 18” x 10” (550 mm x
450 mm x 250 mm) for stay put schematics for double acting actuators.
Mounting: Different assembling options are available:
• On board (panel mounted directly to LEDEEN actuator)
• On 2” pole (mounting kit separately delivered on request)
• Wall mounted (mounting kit separately delivered on request)
Tubing and Fittings:
• Tubing: SS 316L – imperial size (metric available on request)
• Fittings: SS 316 double ferrule type (Swagelok)
Ambient Temperature Range:
• -4º F to 122º F (-20º C to 50º C)
Schematics: For detailed description of available schematic logics please refer to pages 4 and 5
