Pilot Operated Valves 5 Way G1/4 Ports Poppet & Spool Design.
Pneumatic air pilot valves shown within this section are available as a 5/2 way valve function with either a poppet valve or spool valve design. Poppet valves use O-rings, gaskets and seals, designed to offer higher flow rates than spool valves. Spool valves are designed using a stainless steel spool and plastic liner. Although spool valves have lower flow rates than poppet type designs, they are better known for their long life expectancy.
Valve variations include single pilot control with a spring return or double air pilot control with or without priority which overrides signals from the opposite pilot control of the valve should two signals occur at the same time. We also offer 5/3 way double pilot control valves with either all ports closed or all ports exhaust central position.
The main body of the valve is constructed using a light glass fibre reinforced plastic material, the main valve ports are machined from brass providing strength and reliability; main threaded connections are G1/4 with the G1/8 pilot control ports positioned inline to the main ports.
