| Pressure Relief Valves | ||||
| Recommended for all cold water system installations - to protect against damage to piping and pressure tanks. PRV are set at 75 psi or 100 psi- adjustable from 75 to 150 psi. PRV have a +/- 15% setting accuracy. PRVHD are set at 75 psi. PRVHD's are field adjustable and recommended for use up to 300 psi on water systems only. These valves are not T&P valves that are required with water heaters. There is the same need for PRV on cold water pressure tanks. | ||||
