Pressure operated valves are also known as pilot operated valves as an external pilot is used to control the operation of the valve. The pressure of the external fluid
acting upon the piston actuator moves it to the required position – open or closed. These valves can be piloted with either air or neutral gas with options
available for oil or water piloted valves as well. In comparison to solenoid valves, pressure operated valves demonstrate a distinctly higher closing force,
can implement shorter switching cycles and are approved for use in the explosive environments without further safeguards.
