Rotork LP/LH Range - Pneumatic & Hydraulic Actuator
Brand: Rotork PLCRotork 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 declutch-able) or hydraulic manual override if desired.
They are available in both spring-down and spring-up travel direction.
Features- Carbon steel design single and double-acting cylinders. These are electroless nickel-plated to reduce surface roughness and to provide minimum friction and maximum protection against corrosion.
- The piston rods are carbon steel and chromium-plated. This helps prevent corrosion and minimises sliding friction on the dynamic seals. The rubber seals help to avoid slip effect, even after prolonged periods without operation.
- The visual position indicator is directly connected to the valve stem and shows actuator/valve full linear stroke.
- Totally enclosed carbon steel spring cartridge
