Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage. They operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). Valves don’t require a minimum pressure drop between the inlet and outlet for operation. All meet ANSI Class IV for tight shutoff and have a leakage rate of less than 0.01%.

All valves have a single-acting actuator that only requires air pressure to actuate the valve; they automatically return to the valve starting position when the air turns off. The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair.

Normally closed valves are closed unless actuated. Normally open valves are open unless actuated.
