The actuated on-off valves are ideal when remote control is required. The type of actuator depends on the operating pressure, availability of power sources and other process requirement. Pneumatic actuator, therefore allowing fast opening and closing.
Actuator housing, tie rods and piston rods are available in various materials. Short cycle times are achieved by quick exhaust valves. Epoxy paint can be applied to further improve corrosion resistance.
The standard pneumatic actuator is simple and economical to install. Pneumatic actuator can be equipped with override (AB) hand wheel for manual fail-safe and mechanical (AV) or a pneumatic spring (AU) for automatic fail-safe function. Pneumatic Pinch Valve is the cost effective solution to flow control problems. The secret is only rubber sleeve valves only wetted parts. Actuation of the valve, the pinching action is accomplished by pneumatic cylinder. The sleeve’s flexibility allows the valve to close drop around entrapped solid. It is available with NO & NC condition. We also provide the Positioner.
