Solenoid valves are used in hydrodynamic pneumatic and hydraulic frames to control chambers, hydrodynamic engines or larger mechanical valves. They are widely used in shop floor applications, from project and process test hardware to machine gear, including modern blowers for welding and fire cutting hardware.

Solenoid valves are often used in the framework of water systems where a normally unpowered solenoid opens and closes a small pilot valve to activate the basics by applying the weight of the fluid to a cylinder or stomach that is precisely connected to the main valve. The sprinkler frame of the programmed water system also uses a solenoid valve with a programmed controller.

A two-way parker solenoid valve is any type of valve with two ports: a bay and an outlet often referred to as "An" and "gastric muscle", respectively. From basic on / off to increasingly complex variable flow applications using siphons and VFDs, two-way valves are used in many applications.
