High Tensile Pressure Relief Valves are suitable for natural gas, LPG, propane and other dry and non aggressive gases. These Pressure Relief Valves shut off automatically in case the regulated pressure goes below a preset value. These Pressure Relief Valves are made from quality grade raw material that ensures durability of usage. High Tensile Pressure Relief Valves can be reset manually and opened only after verifying and rectifying the cause that triggered the shut off.
