Check Valve - Double Door
Check Valve - Double Door
Energy-Efficient Dual-Disc Valve Design for Industrial Applications
Energy-Efficient Protection Against Flow Reversal
Bray's Rite Double Door Check Valve features lightweight dual discs, responsive independent springs, and a durable resilient seat for reliable flow-activated operation with tight sealing and reduced water hammer potential.Features
COST EFFICIENT DESIGN:Low weight and short laying length saves initial cost, requires less space, and is easier to install
QUICK CLOSE:Independent springs provide quick-closing, non-slam shutoff for reduced water hammer potential
LOW CRACKING PRESSURE:Lightweight, spring-loaded discs have low cracking pressure for energy efficient operation
MINIMAL HEAD LOSS:Contoured body provides a short and straight flow path with minimal turbulence
