For use on gas, liquids or steam, the M-Valve is an air operated proportional control valve for 1/4 ” or 1/2” lines. The interchangeable plug and seat trims are available with CV values from 3.0 down to 0.00007, with a control range of up to 40:1. The standard actuator is available with Air - to - Open or Air - to - Close action, using 3-15psi. For high line pressures or for very low flow control a pneumatic positioner is recommended.

To specify and size the M Valve trim required, please state: Fluid type, SG, viscosity, Line pressure, temperature, valve pressure drop, Max flow rate and flow range required. Air - to - Open or Air - to - Close.

Suitable for:

  • Pilot plant control
  • Dosing, blending or flavour flow control
  • Cryogenic liquid control for cooling
  • Hazardous area applications
  • Bellows sealed units for dangerous gases, nuclear applications.
