Low Temperature Safety Valve
Introduction:
The overall material of the low temperature safety valve is cast from stainless steel. After cryogenic treatment, it is processed and assembled. The valve adopts a fully closed bonnet and bonnet structure. When the safety valve is opened and discharged, the medium will not leak outward, but all will be discharged through the discharge pipe, which can prevent dust and other impurities from entering the valve. It is applicable to the low temperature working condition of 196-200 ° C as an overpressure protection device.
Product features:
Full lift structure, large displacement
All parts are subject to cryogenic treatment
Metal seal surfacing with hard alloy, fine grinding of sealing surface, ensuring high sealing performance and long service life
Non metal sealing materials have outstanding creep resistance, ensuring high sealing performance under temperature conditions
The material selection and processing technology of the spring are exquisite, and the testing and inspection are strict to ensure that the safety valve can be opened accurately and reseated timely under warm conditions
The discharge coefficient of the safety valve is high and the discharge is stable under low temperature conditions
