Excess Flow Valves

XVH Series Excess Flow Valves act as flow switches that automatically close when a flow spike occurs,

preventing uncontrolled release of system fluid. The XVH Series is available in automatic and manual
reset versions, depending on system requirements. Automatic reset XVH Series have an “anti-clog”
wire which increases reliability by preventing a build up of system fluid in the bleed port. The XVH
Series are high pressure (0 to 6000 psig [414 bar]), high performance, quick acting, zero leakage, low
maintenance excess flow valves that will help provide a reliable and safe working environment.
