C46 Series valves from Hydra-Cell Industrial Pumps, Wanner Engineering, prevent excess system pressure by bypassing total system fluid flow. They contain no external springs or moving parts, are fully adjustable, and can be serviced in place without removing fittings or plumbing. They are available with stainless steel or brass bodies to suit various application needs. The Hydra-Cell C46 Series valve design consists of a simple tapered plunger and 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 the pressure. These valves are designed to handle flow up to 10 gal/min and pressure to 1500 lb/in2.
