The Hydra-Cell Valve design is simple: a tapered plunger with a valve seat. When excess pressure overcomes the adjustable spring pressure on the plunger, the plunger lifts off the seat, allowing fluid to bypass and reduce system pressure. When a Hydra-Cell Valve is mounted in the discharge line, its modified flow through design reduces wear on the plunger and seat. Baffles on either side of the plunger and seat extend life by directing the flow around these internal components.

For service, simply remove the top of the body and replace the worn internal components. Hydra-Cell Valves can be serviced in place without removing any fittings or plumbing.
