Back pressure valves using diaphragms are designed to protect pumping systems from over pressure damage caused by defective equipment or blockage in the pump system line.
Yamatho's supplier is a manufacturer of high quality back pressure valves made from a variety of different materials to suit most needs. In most cases we are able to ship within 2 – 3 days after receipt of order because of our extensive inventory.

Diaphragm back pressure valves operate when the pressure in the pumping system exceeds the preset pressure of the valve. The diaphragm is held against the valve seat by an internal spring. When the preset pressure is exceeded the diaphragm is forced up and the system fluid flows out the relief port, back to the system fluid tank or to the suction side of the pump. The valves are pre-set at 40 psi; however they are field adjustable from 10 to 150 psi, (optional 350 psi) via the adjustment screw. The relief valve should be set approximately 15 psi higher than the system pressure. Installation should be made as close to the pump as possible.
Yamatho performs a pressure test on every back pressure relief valve prior to shipping.
This ensures the unit will operate leak-free and to the specified pressure ratings.
These Yamatho back pressure valves come standard without a gauge port or gauge. When ordering please specify if a gauge port and/or gauge is required.
