MAP Pneumatic Actuator

STRUCTURE

1. 1.Indicator

Multi-function position indicator with Namur is convenient for mounting accessories such as positioner, limit switch and so on.

1. 2.Pinion

The pinion is high-precision and integrative, made from nickle plating steel, full conform to the standards of ISO5211, DIN3337, NAMUR Standard. The size can be customized and stainless steel is available.

1. 3.Actuator Body

According to the different requirements, the extruded aluminum alloy STM6005 body can be coated with hard anodized, polyester PTFE or nickel.

1. 4.End cap

End caps are made of aluminum material, and can be coated with polyester, metal powder, PTFE and nickel.

1. 5.Piston

The twin rack pistons are made of aluminum die-casting coated with hard anodized or steel coated with Zinc. Long lifespan, fast operation and reversed rotation by simple reversing.

1. 6.Stroke Adjustment

The two independent external travel bolts can accurately adjust ±5°at both open and close position.

1. 7.High Performance Spring

Preloaded springs are made from high quality material for resistant to corrosion and longer lifespan, which can be demounted safely and conveniently to satisfy different requirements of torque by changing quantity of spring.

1. 8.Bearing & Guide

Made from low friction, long-life compound material, to avoid the direct contact between metals. The maintenance and replacement are easy and convenient.

1. 9.O-rings

NBR O-rings provide trouble-free operation at standard temperature ranges. Viton or Silicone for high and low temperature.

Application

Applied on small/middle rotary valves, such as ball valve, butterfly valve and so on.

Technical Parameter

1. 1.Work Medium

Dry or lubricated air or non-corrosive air. Dust below 30 micron.

1. 2.Air Supply Pressure

Min.Air pressure is 2 bar. Max.air pressure is 8 bar.

1. 3.Operating Temperature

Standard: -20 to +80℃

Low: -40 to +80℃

High： -20 to +120℃

1. 4.Stroke Adjustment

±5°adjustment range at 0°and 90°point for rotation.  

Operating Principle

Double Acting

1. Air from port A forces the points outwards, causes the pinion to turn counter-clockwise while the air exhausted through port B.
2. Air from port B forces the pistons inwards, causes the pinion to turn clockwise while air exhausted through port A.

Single Acting

1. Air from port A forces the pistons outwards, and causes the springs to compressed, the pinion turns anticlockwise while air exhausted through port B.
2. Then loss of air force, compressed spring force the piston inwards, causes the pinion turns clockwise.

The non-standard rotation direction is to reverse the position of two pistons, the introduction of pressure into the A can rotate clockwise, the introduction of pressure into the B can rotate counterclockwise.
