P/H

P (pneumatic) and H (hydraulic) ranges actuators are designed to provide a rotary, quarter-turn movement for either on/off or modulating duty. The robust design incorporates double sealing for superior environmental protection and features a one-piece ductile iron cast centrebody. Superior design features enable a much longer service life than competitive products. P and H range actuators are capable of a least 200,000 cycles under full load.

• Pneumatic torque output up to 88,000 lbf-in (9,942 Nm).
• Hydraulic torque output up to 95,425 lbf-in (10,780 Nm).
• Steel and ductile iron construction.
• Inherently safe, factory welded spring-return module.
• Exclusive Rotork double ‘O’ ring sealing for proven protection against leakage in oil-filled service.
• Special build available for nuclear power plant safety related valve applications class 1E, in standard IEEE323.
• AWWA C540 compliant build available.
