STRAVAL RVI20-02T-N4793 , 1/4” , Range 0.3-3.5 PSIG For Sale

This safety relief valve can be used for relieving pressures and maintaining upstream line pressures to a specific set pressure. This diaphragm valve can also be used for bypassing fluids or gases. Only clean liquids and gases are recommended. When liquids contain debris or other solid matter that might cause improper operation of the diaphragm valve, a filter or strainer with a fine wire mesh should be installed before the inlet of the valve. Basket strainers or filters can be purchased from Straval to solve this problem. This valve is used where accurate set pressures must be maintained. This is made possible because of the large diaphragm area used to sense the inlet pressure. Compared to higher-pressure piston models, this valve has a very low hysteresis between opening and closing pressures. See available orifice sizes and flow Cv below.
