The Control Valve Range is a highly flexible modular solution designed to meet the needs of every application.
membranepneumatic actuators,STI is a series of direct stroke pneumatic actuators specially designed for regulating valves.compact structure,large output force,light weight,high reliability,easy operation and so on.
MAXSTI film actuator adopts spring balance,responds to the pneumatic output signal added to the film of actuator by valve positioner,and determines the position of the actuator is determined by the compression of the actuator spring,and the travel range is determined by the stiffness of the actuator spring.
thin film actuator can be used with direct striokes(such as single,double seats,sleeves,diversion valves) and similar applications.It is widely used in electric power,metallurgy,petroleum,chemical industry,paper making,pharmaceutical,food,machinery,environmental protection and other industries.
- Excellent long lasting accuracy and reliability isachieved through the use of multiple springs and roll-ing diaphragm in the actuator.
- The use of involute rolling diaphragm permits longtravel and excellent linearity without the need ofexpensive hardware normally associated with dia-phragm actuators.
- A wide selection of spring ranges are available.
- The actuator is field reversible between direct andreverse acting.
- The rugged one piece yoke, pressed steel diaphragmcase and special nylon reinforced diaphragm providedependable, high thrust performance.
- Optional handwheel for manual operation.
