MAT-P type LAP Pneumatic piston actuator in heavy duty design for industrial use on globe and gate valves, DIN/ISO 5210 mounting flange. Available in single-acting design with opening / closing spring or in double-acting design; suitable for mounting limit switches or positioners to suit customer requirements, factory-mounted. Settings are adjusted during factory test run.


Pneumatic piston actuators are designed for valves with a linear stem movement (globe, diaphragm and gate valves). They are suitable for building services, industrial plants, power stations, the food and beverages industries and the chemical industry. Pneumatic actuators can also be used in potentially explosive atmospheres.
