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.

Ideal replacement for a solenoid valve that fails frequently, specially in cooling blowdown applications.
Motorized water control valve with electronic return to close when power is removed. This is not a spring loaded actuator. With a nickel plated brass or SS316 body and 1 ", 3/4" or 1/2" FNPT thread, this valve is extremely resistant to hard water or water with high TDS content.

The actuator in this water control valve can handle 95 to 250 VAC and comes with a manual override, for maintenance and operation in case of power failure. With a IP67 enclosure, this is a heavy duty valve that can withstand water splashing and dust.

How much is costing you a failing solenoid valve? Solenoid valves are the most used type of electrically actuated valves for water applications. Unfortunately they use a small orifice to control the water flow. This presents two limitations; it can easily be plugged by solids in the water and, limits the water flow, creating big pressure drops. Our motorized ball valves replaces both electrically, and mechanically, any solenoid valve, without the problems mentioned before.

The Compact ClO2+ (Chlorine test kit) meter provides field analysis of chlorine and chlorine dioxide test kit using the DPD method.
The original Palin system was designed for monitoring of all forms of chlorine. Dr Palin extended the method to measure alternative disinfectants such as chlorine dioxide – a powerful and increasingly popular biocide. The Compact ClO2+ meter delivers the following features:
Available in a choice of hard or soft case kits, the Compact ClO2+ meter is simplicity itself operating with four intuitive keys. Accessories include our unique Neutral Density Filter (NDF) check standards for validation in the field.
