GENERAL DESCRIPTION. Reliable Pressure Relief: Hayward Pressure Relief Valves protect piping system components from damage due to over pressurization. The valves work by sensing system pressure. When the system pressure exceeds the set pressure, the force of the excess pressure moves the valve piston off its seat to relieve the excess pressure and diverts some of the flow out the discharge port. Easy to Set Pressure: Hayward Pressure Relief Valves can be set by hand, no tools are needed... (read more)Browse Pressure Relief Valves Datasheets for Hayward Flow Control -

Fluid Transfer Valves
. Thus, a ball valve has relatively good throttling characteristics at low flow. The ball valve is somewhat similar in its operation to the butterfly in that a one-quarter turn opens or closes it, and the valve presents little resistance to the flow of fluid through it. It has two advantages over...
