LP/LH
LP/LH
LP/LH pneumatic and hydraulic actuators for linear valves in double-acting or spring-return configurations to suit all valve sizes. Offering 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.
Features
• Optional handwheel (fixed or de-clutchable) or hydraulic manual override available in both spring-down and spring-up travel direction
• Hammer blow and standard valve stem coupling designs available
• Carbon steel design single- and double-acting cylinders
• Electroless nickel-plated cylinders provide minimum friction and maximum protection against corrosion
• Carbon steel and chromium-plated piston rods prevent corrosion and minimise sliding friction on the dynamic seals
• Rubber seals help to avoid slip effect, even after prolonged periods without operation
• Visual position indicator directly connected to the valve stem shows actuator/valve full linear stroke
• Totally enclosed carbon steel spring cartridge
• Certified to IP 66M/67M and ATEX 2014/34/EU
• Certified in accordance with PED 2014/68/EU
• Certified suitable for use at SIL3 as a single device in accordance with IEC 61508
