Control Valves

Air Volume Boosters

The AVB Series is an air volume booster that is mounted between the positioner and actuator. It provides the actuator with a high air flow output, whose pressure corresponds exactly to the signal pressure.

For more than 70 years, OCV Control Valves has manufactured and supplied hydraulically operated, diaphragm actuated, automatic control valves.  Our high quality control valves can be found throughout the world – from municipal water systems in the US, to Russian oil refineries, to irrigation systems in Europe.

The Block & Bleed Valve (BBV) is a NAMUR mounted module for the actuator. The BBV is used as a bypass valve for use with a manual override to shut off supply air and vent actuator ports. The BBV may also be used as a lockout valve which when properly implemented, will satisfy OSHA Standard 1910.47, “The Control of Hazardous Energy.”

A-T Controls’ Butterfly Valve Tee Assemblies provide a cost-effective, alternative to a 3-way valve solution. Available for lug style butterfly valves, these unique tee assemblies can be customized to fit your application. Consult factory for valve selction and assembly options.

The A-T Controls V Series rotary valve is a throttling control segment-ball valve that provides high flow capacity with optimum characteristics for industrial markets including Pulp and Paper, Refinery, Chemical, and Petrochemical Industries

The Triac XC Series Actuators are CSA Certified Type 4, 4X, 6 & 7 for hazardous locations and meet UL 1203 standard. The actuators are rugged and reliable with powder coated anodized aluminum housing for use in Oil, Gas, Chemical & Power Gen applications. The XC Series is the perfect match for resilient or high-performance butterfly valves and dampers because of the self-locking, double reduction worm drive and torque switches. The XC Series is also ideal for ball, plug or any rotary valve requiring automation in a hazardous location.

• Stable setting pressure: Constant output pressure under variable flow rates or supply pressures.
• Corrosion-resistant construction: Aluminum die-casting are finished with chromate.
• Filter: It is designed to equip with high capacity 5 Micron Filter housed.
• Self Relief function: Self-Relief function is operated when the output pressure is higher than setting pressure.
• High flow capacity: It is designed to supply sufficient flow.
• Disc: It is strong in oil resistance.
• Tight shut off: A soft, rubberized pin provides a positive shut off and compensates for dirt and other foreign matter.
