YD13H/YD43H pilot-type super-large diaphragm high sensitivity pressure relief valve is a new type of pilot-type super-large diaphragm pressure relief valve developed by referring to foreign advanced products. The pilot-type super-large diaphragm high sensitivity pressure relief valve has been greatly improved on the basis of ordinary pressure relief valve. The diaphragm uses a new material, and greatly processes the working area, so the valve upstream pressure or downstream load changes can be timely and accurate feedback to the main valve diaphragm, to adjust the opening of the main valve, to ensure the stability of downstream pressure. Another prominent feature of the pilot-operated super-large diaphragm pressure relief valve with high sensitivity is that multiple pilot valves can be installed and exchanged on the same valve body to realize temperature control, upstream pressure control and remote switching control while stabilizing the pressure.
