Features£º
¡ñ Product is designed, mainly for the cryogenic temperature conditions, simple structure, economic.
¡ñ Tightness surface is deposite with stellite, excellent flatness and surface finish of the seating surface by precision machining and lapping to have high degree of seat tightness and long using life
¡ñ Creep-resistant non-metallic sealing materials are prominent in the cryogenic temperature operating conditions, ensure good tightness
¡ñ Applied with strict arts, tests, inspection and selecting of the material, the spring can insure the exact open and the timely seatback at cryogenic temperature conditions.
¡ñ The valve can relieve steadily with high discharge coefficient at cryogenic temperature conditions.
¡ñ Blowdown control is provided with adjustable nozzle ring only
