Often used to control single-acting, spring-return air cylinders, these valves have a third threaded port to exhaust media. They operate on electricity to automatically start and stop flow.

Valves are fail closed and exhaust media unless actuated; when actuated, they close the exhaust port and reverse the direction of flow to send media to equipment. They don’t require a minimum pressure drop between the inlet and outlet for operation. Body is 303 stainless steel for good corrosion resistance. Coils are rated IP69 for protection against dust and high-temperature, high-pressure washdowns. The actuator is directly mounted to the valve body to minimize movement and reduce wear.
