Pneumatic and Hydraulic Actuators for Linear Valves
Rotork manufacture a comprehensive range of double-acting and spring-return pneumatic and hydraulic actuators to suit all valve sizes. Our LP/LH linear actuators offer the advantages of compact size, high performance and a simple but highly reliable design. They are ideal for operating on/off and control functions of both globe and wedge gate valves. Both spring-return and double-acting configurations are available with either pneumatic or hydraulic cylinders.
LP/LH actuators can be fitted with handwheel (both fixed and declutchable) or hydraulic manual override if desired. They are available in both spring-down and spring-up travel direction.
