Weighted Relief Valves



Weighted Relief Valves are used for pressure relief. They are simple devices that can be easily adjusted to the desired set point. They operate by allowing air to pressurize a weighted cylinder. As the pressure increases, a cast opening in the piston is exposed to ambient air letting system air escape.
