Pneumatic actuator VD series

linearcontrolintegrated

Neles spring return VD series diaphragm type linear actuators are designed for use in both modulating control and on-off service. These actuators offer an extremely long cycle life and are well suited to operate linear valves with small to medium thrust requirements. Features Spring return diaphragm actuator for linear modulating control and on/off applications Low friction diaphragm design provides precise control and reliable operation Corrosion resistance coating against severe weather, chemical and petroleum environments Field reversible for spring to open or close Mechanical position limitation and easily accessible side hand wheel optional Suitable for safety integrated systems up to and including SIL 3 in accordance with IEC 61508
