SPC4.M18 Valve Series

METRIC Cartridge - 350 bar
Direct acting check valve - Pilot Piston to open

More details

Description
Cartridge style, normally closed, single pilot check valve.
Cartridge is closed until sufficient pressure is applied on port 1 to
reach the bias spring setting, lift the poppet and allow free flow to
2.
The valve is normally closed from 2 to 1.
When sufficent pressure is applied on port 3, the pilot piston lifts
the poppet from its seat and allows flow from 2 to 1.
Very limited leakage in the check condition.

Technical Features
All external surfaces are zinc plated and corrosion-proof.
All valve parts are made of high strength steel. Poppet is hardened
and ground to guarantee minimal wear and to extend service life.
Pilot piston is hardened and ground, sealed to prevent leakage.
Single-piece, high durometer, extrusion resistant seals.
Optional bias springs for back-pressure application flexibility.
Metric cavity.
