19BV Series Pressure Relief Valve

1900 Safety Relief Valve

19BV Series Pressure Relief Valve

The 19BV is an economic, direct spring operated, soft-seated, balanced valve incorporating balanced disc and cage guided assembly creating optimal performance in both liquid and air service where built up or superimposed back-pressure could be an issue.

The seat at the inlet orifice, and the area of the o-ring guided disc in the cage are equal. The disc/cage assembly uses a plastic bubble tight seat at the inlet nozzle for upstream pressures and an o-ring guided disc in the cage as the balanced seal for downstream back-pressure. The vented to atmosphere upper body allows the valve’s balanced disc/cage assembly to remain fully functional in superimposed back-pressure conditions having little to no effect on set pressure.

A cost savings answer to the high-end bellows valves, in a simple and reliable design.

The Taylor 19BV Pressure Relief Valve has numerous application uses. Since the Series 19BV is certified for both gas and liquid on both orifices, it can be installed where relief applications that have variable back pressure are present. Thermal valves, pump recycle, separators (liquid side), water knockouts, etc. are just a few examples of application uses.
