Actuator khí nén MA-Series

The diaphragm actuators of type series MA are mainly used to operate linear stroking valves. Furthermore  they can be used together with appropiate gear mechanisms for operating rotating valves, as well as for  any linear movements in the range of strokes and powers.

Diaphragm effective areas: 70 cm³ to 1070 cm³

Shut off forces: 0,5 kN to 122 kN  Strokes: 10 mm to 140 mm  Temperature range: -30 °C to +90 °C  Allowable airpressure: up to 6 bar

Various combinations:

• 5 actuator sizes
• 120 different spring combinations
• Numerous strokes realizable
• Completely and party made of stainless steel

Features:

• Heavy duty type (also adapted for rough operation)
• Precise stem guide, therefore low wear and long life cycle
• Component parts replaceable, low maintenance costs
• Pillar yoke acc. to NAMUR, easy mounting of control valves and other parts.
• The simple acting actuators are reversible
• Double acting is available for all actuator sizes
• All actuators can be provided with handwheel or stroke limitation
