diaphragm relief valve

Sentry Back Pressure Regulator/Relief Valve (BPRV) maintains pressure and analyzer flow at constant level. It also guards critical sampling parts as a relief valve. The standard pressure setting is 20 psig or 1.4 barg. Other pressure settings are available on request.

BPRV is a non plug-in type device. When used in combination with a VREL® or needle valve, it provides accurate pressure reduction and control. The valve is the most reliable way of maintaining a constant flow rate to on-line analyzers. It has been specifically developed for steam/water sampling service. It will not wire draw or wear away in regular service. The relief valve is fail safe.
