Budenberg 6GM Over Range Protection Valve (Gauge Saver)

Product Description

The Budenberg 6GM Over Range Protection Valve (Gauge Saver) has been primarily designed to protect pressure gauges (or other instruments) against over pressure conditions, either designed or accidental due to failure of other systems. The operation of the unit is based upon a piston assembly that can open or close dependant upon the applied pressure at the inlet. The unit should be fitted directly to the instrument to be protected. An internal spring holds the valve open under normal conditions. When the inlet pressure exceeds the setting pressure of the valve then the spring is compressed and closes the valve. Setting is achieved by selection of the appropriate spring to operate in the correct range and adjustment of the spring adjuster until the desired operational setting is achieved. Units can be used on any clean, non viscous fluids or gases that are compatible with the chosen materials of construction. We have an interesting article relating to Pressure Gauge Selection in the Technical section on this website.
