Pneumatic valve actuator SF

rotarypistonIP65

Equiped with an automatic control switch, Zhonghuan's pneumatic actuator uses nitrogen gas or natural gas as a power source. It is widely used in petroleum, chemical, metallurgy, food, and other industrials that requires control of valves. It can drive ball valves, butterfly valves, plug valves, and any 90 degree rotational type valve. 1 ISO Standard Dimensions Actuator's mounting interfaces with valves meet ISO standard requirements in each torque range. 2Wear Resistant A piston bar and guiding bar with fine surface treatment are combined with a self-lubricating bearing, ensuring superior abrasion resistance and extending the service life of all sliding parts. 3High Efficiency The piston bar and guiding bar with fine surface treatment are combined with a self-lubricating bearing, ensuring superior abrasion resistance and extending the service life of all sliding parts. 4Corrosion Resistant SF-series actuators incorporate more than 3 layers of protective coatings which can withstand severe service conditions. The inner surface of the gas cylinder is coated with PTFE to enhance its corrosion resistance and self-lubricating performance. 5Modular Design The SF-series actuator is composed of driving module, cylinder, spring, and optional side units. Those modules are designed for easy installation, disengagement, replacement, and fastening. Each module can be purchases separately for a minimum spare-parts inventory.
