SS Pressure Proportional Relief Valve 50-1500 psig 1/2 in. MNPT TO FNPT pressure relief valve

Application of Pressure relief valve

The RVH and RV series safety valves are proportional leaked valves. When the pressure rises, it gradually opens, so they do not have a capacity level when the given pressure rises (cumulative), and they do not check according to ASME or any other standards. Some system applications require a security valve to meet special security criteria, so system designers and users must determine when to apply these security standards and whether these security valves meet the safety standards.

Operate of Pressure relief valve

■ When the system pressure reaches the set pressure, the safety valve is turned on, and the system pressure falls to below the set pressure.

■ Safety valve selection and installation covers the need to set the pressure to set pressure, and put the corresponding label on the cap cover.

■ For valves that have not been used for a period of time, the initial pressure of the initial loading may be higher than the set pressure.

■ Set pressure and re -seal pressure Setting pressure is the upstream pressure when there is a fluid for the first time. At room temperature, after the initial load is completed, the set pressure of each valve can be repeated within the range of ± 5 %. The sealed pressure is the upstream pressure when the flowing body flows out, and the sealed pressure is always lower than the set pressure

RVH series

■ Used for liquid or gas

■ Set the pressure: 7 kinds of spring can be selected, which increases the range of selection of the setting pressure.

■ Inner diameter: 3.6mm

■ Balanced valve stem design, eliminating the effects of back pressure on tidy pressure

■ Work temperature: -23 ℃ to 148 ℃ (-10 ° F to 300 ° F)

■ Adjustable valve cap, adjustable and setting pressure

■ Anti -pine holes can effectively maintain the setting of settings

■ Various sealing materials are available

■ Label label the range of the whole pressure

■ When the setting pressure is lower than 1500PSIG Control the handle, this handle can open the valve without changing the setting pressure

■ Conncetion size: 1/4 "to 1/2", 6 to 12 mm dual card sets 1/4 "to 1/2" thread
