Watson McDaniel 10691 Series Relief & Back Pressure Valve
The Watson McDaniel series 10691 relief & back pressure valve automatically maintains desired maximum pressure in a vessel or on a system by relieving excess pressure into a lower pressure system or to atmosphere. Typical applications include pump bypass control valves, or for protection against intermittent overpressure conditions on liquid systems. Usable on a variety of liquid systems, not usable on steam systems. Suitable for systems where bubble-tight shutoff requirements must be met.
