Adding a pneumatic actuator to a ball or butterfly quarter turn valve allows them to be remote controlled with compressed air to increase system automation. Pneumatic actuators are a reliable solution to control larger valves at a relatively low investment cost. These valves commonly have an ISO 5211 mounting flange, so they are prepared for an actuator. This actuator is compatible with ISO 5211 F10 or F12 valves and has a 27 mm star connection for square drive shafts. The shaft size can be reduced using adapters. Please carefully check the datasheet and the flange dimensions of your valve, as there are many variations on the market. This actuator generates 180.5 Nm of torque at 8 bar, but it has a control pressure window of 6-10 bar to increase/decrease torque. The actuator is single acting spring closed to conserve on compressed air and it returns automatically to starting position in case of air or power loss. It is designed with a reliable aluminum rack and pinion rot ational operation. Using throttle valves on the outlet ports (after the solenoid valve) allows the adjustment of the rotational speed. These actuators are durable with an anodized aluminum housing and an aluminum cover. Due to the NBR seal, the temperature range is -20°C to 80°C. Connect an air hose to the G1/4" connection points on the side or mount a 1/4" Namur solenoid valve (VDI/VDE 3845) directly onto the actuator. Also, a position control or limit switch box can be mounted on the top of the actuator according to VDI/VDE 3845.

Pros:

• Single acting conserves compressed air and the valve will return to initial position in case of air or power loss.
• Suitable for most quarter turn valves with ISO 5211 F12.
• Ability to directly mount a Namur solenoid valve to reduce fittings and tubing.
• Optional FKM seal to increase max temperature.
• Fast opening/closing.
• Mechanical indicator on top shows the valve position.
• Can be equipped with a limit switch box.

Cons:

• Single acting gives less control than double acting actuators.
• Requires compressed air system and a solenoid valve to control the air supply.
• Energy consumption is higher than compared with electric actuators.

VS Series

The VS quarter turn pneumatic actuators allow you to control ball or butterfly valves with compressed air. They offer a reliable and robust solution to automate larger valves at a lower investment cost than electric actuators. They are mounted onto quarter turn valves with an ISO 5211 top flange Designed with a reliable aluminum rack and pinion rotational operation and designed to be either single acting (spring open or spring close) or double acting for increased control. The standard temperature range is -20°C to 80°C with an NBR seal, but an optional FKM seal is available for an increased maximum temperature of 120°C All valves have a G1/4" Namur interface according to VDI/VDE 3845 with either G 1/8" or G1/4" threads
