Omega Engineer Inc. introduced BVP70/BVP80 Pneumatic and Electric Actuated Ball Valves. The pneumatic actuators on the BVP/BVPS80 and BVP/BVPS70 Series offer the latest technology for pneumatically actuating BV80 Series ball valves with NPT threads and BV70 Series with compression fittings. The BVP80 and BVP70 Series are a combination of the three key elements for long, reliable, trouble free life-a premium quality ball valve, a quality actuator designed to meet the torque requirements of the valve, and a mounting system which assures alignment and rigidity.

The BV80 and BV70 ball valves low operating torque makes possible a compact actuator that is both economical to install and operate. Precise machining of all the valve components, including the seats, controls the sealing preload. This assures bubble-tight sealing, minimizes the operating torque and optimizes the valve life.

The mounting system precisely couples the actuator drive shaft to the valve stem. Additionally, the valve stem nut is fixed within the actuator shaft. These features combined with a rigid mounting bracket, results in a pneumatically actuated ball valve which minimizes backlash, assures optimum stem seal life and eliminates any possibility of stem nut backing off while in service.

The BVPS80 and BVPS70 Series offers a spring return model requiring only 50 psi supply air that can spring to open or close without loss of output torque from the air operated side. This is achieved by two opposing lightweight Zytel^® or manufactured aluminum housed spring modules that are fully compressed by air operated diaphragm pistons.

All BVPS80 and BVPS70 Series are designed to operate using an air supply of 3.5 to 8.6 bar (50 to 125 psi). The air can be delivered by direct mounting pilot valves having NAMUR interfaces or from remote pilot valves connected via means of 1/8 NPT female threaded orifices in the actuator face plates.
