Pneumatically-operated valve M

regulatingfor gasproportional

The M Valve is a miniature air operated proportional control valve for use on liquids or gases. Available for 1/4and 1/2line sizes, a wide range of inner valve trims offer flow control with CV values from 3.0 down to 0.00008. Each valve has a control range of as much as 40:1 and with interchangeable trims the M Valve is ideal for pilot plant control, representing a scaled down version of larger process control valves. With linear, equal percentage and quick opening control characteristics, the M Valve also has specific application in dosing, sampling and blending systems. Standard valve material is forged 316 Stainless Steel: alternatives of Hastelloy, Monel, PVC or carbon steel body materials are available with Stellite or other trim materials as required. The standard Air actuator uses a 3-15 psi control input of either Air-to-Open or Air-to-Close. For higher line pressure applications a standard top mounted positioner is recommended, incorporated into the valve. For high integrity applications, alternative designs of valve seal are available. Extension bonnets or cooling fins are used for cold service or high temperature duty.
