Cartridge Check and Relief Valves
Kepsel® cartridge valves are designed for simple installation (no expensive machining for cavity) and offer the same outstanding performance as their counterpart Kep-O-seal® inline valves. These spring-operated poppet valves, with optional relief settings, allow free flow in only one direction and prevent backflow.They also are used for relief and by-pass functions; however, they should not be used as safety valves. Kepner's Flexible Seal Seat™ ensures bubble-tight shutoff of liquid or gas, and long service life. Standard and specialty valve designs handle a wide variety of applications, and are ideal for use in sub-plate and manifold assemblies, pump inlet/outlet, and cylinder blocks.

Features and Benefits:
- Flexible Seal Seat™ for zero leak (bubble-tight) seal at low and high pressures
- No threaded connections (avoid potential leakage)
- O-Ring seal positively secured
- Poppet stop inside valve body prevents spring from bottoming out
- Generous flow passages allow full flow with minimal pressure drop
- Compact, easy installation
