Pilot Operated Poppet Valves

UNIJET direct pilot operated valves can be used with air media where quick, positive control is required. With optional seals, they require no lubrication, making them ideal for non-lube air service.

Valves feature a large resilient poppet that provides bubble-tight closure, even under low pressure conditions. Aluminium construction and choice of seal materials provide excellent compatibility with air media.

Top cover and bottom hex nut is easily removed for quick access to valve’s one-piece poppet assembly. O-ring seals on poppet and O-ring pilot piston seal prevent controlled media from entering pilot chamber.
