Plastic Actuated Valves

Pneumatic Type-14 Diaphragm Valve (1/2" - 4")

The Type-14 diaphragm valve is available with an optional pneumatic actuator for operation via a pressurized air supply. The pneumatic actuator is available in both air to air (double acting) and air to spring (single acting) styles. The actuator replaces the valve bonnet and is an integral part of the valve. The actuator is operated with a Nitrile diaphragm which is connected directly to the valve diaphragm for quick response times. The NAMUR mounting pattern on the top of the actuator gives the option for mounting limit switches, positioners and/or a solenoid for automation. The housing is made from glass filled polypropylene for high strength and chemical resistance. A visual position indicator at the top of the actuator allows the user to confirm the valve position.

Ideal Applications Include:

Chemical processing, bleach plants, aquariums, mining, water treatment, landfills, swimming pools, power plants
