RCVC Red Circle Valve Controller

The VRG Red Circle Valve Controller provides accurate positioning of natural gas control valves via electronic signal. The RCVC can accept analog or discrete input signals. The RCVC is compatible with all VRG Controls control valve actuators and may also be installed on virtually any design of pneumatic control valve actuator. The Red Circle Control Valve features zero steady state consumption with an ability to discharge emissions to a suitable nearby pressure system. The high pressure capability of the RCVC system allows for efficient use of more compact pneumatic actuators. The RCVC is equipped with the most advanced programmable control capabilities, diagnostics and operational features to ensure the highest performance and easiest integration on new or retrofit applications.

 
 

Linear Control Valves

VRG Controls’ Linear Control Valves are ideally suited for natural gas control applications.  They can accommodate moderate and severe service.  The cage guided design features trim options to address characterized flow and noise attenuation per application.    The modular format can accept a variety of actuator and trim configurations and actuators to match your application needs.  

The linear control valves are ideal for:

  • Low to Moderate Flow Rates

  • Aggressive Pressure Drop Applications

  • Power Plant Fuel Gas Feed

  • “Trim” Type Control Runs

  • Natural Gas Transmission Pipelines

  • Natural Gas LDC Gate Stations

VMO Valve Manual Override

VMO Valve Manual Override is the ideal device to provide manual operation of pneumatically actuated control valves. The VMO allows the operator to override primary control instrumentation and position the actuated valve in open, closed or any intermediate position.

PRCV Pipeline Rotary Control Valves

PRCV Pipeline Rotary Control Valves are rugged, trunnion mounted configuration with the durable features necessary for reliability and high performance in natural gas control applications. The high capacity design of the PRCV-FP series provides a full opening, high capacity design with high flow range-ability. Higher performance trims are available in our PRCV-STH1, PRCV-STH2 and PRCV-STHP series to provides additional noise attenuation and extended flow range-ability. The trunnion platform is equipped with VRG Control Specification features necessary to ensure maximum control accuracy and reliability for gas pipeline regulation applications. The PRCV mates seamlessly with VRG RHPA double acting and spring return actuators and control instrumentation to create the highest performance pipeline control valve package on market. The PRCV-FP Series can incorporate the Below Ground configuration when utilizing RHPA Series Actuators for maximum noise attenuation with maximum capacity and lowest cost.
