Since the valve performance and reliability is directly related to the safe and stable operation of the device, it is necessary to strictly implement the relevant standards, such as API, ASME standards and other valve brands in design, material selection, manufacturing, testing, etc., and the whole process of strict quality management. In order to meet the domestic industry and foreign standards for safety valve have advanced level of requirements, from the beginning of eight years, after the successful development of a common safety valve, has developed a pilot safety valve and switchable valve. ① adjust the valve discharge pressure and reseating pressure valve must be open to all high action test, so the valve, only in the test device capacity, or after installation to be protected on the device may only be carried out in safety valve. The adjustment method varies depending on the valve structure. Shandong Everbright Valve Co., Ltd. specializing in the production valve manufacturers, welcomed the new and old customers to order our products! Selection principle of high pressure steam generation equipment bypass valve, generally used in a safe and controlled dual function of pilot safety valve if the requirements of the safety valve to make periodic open test valve type, should be used to enhance the wrench with a safety valve. When the pressure reaches more than 75% of the opening pressure of the medium can be used to enhance the wrench slightly lifted from the valve seat to check the safety valve opens flexibility; cast steel valves if the medium temperature is higher, in order to reduce the spring chamber temperature, generally enclosed safety valve when the temperature exceeds 300 ℃ and open valve temperature than 350 ℃ and time, should be used with radiator valve; valves, valve Weifang, Shandong, China Everbright Everbright A38Y16C safety valve from the valve Ltd. provided.
