FeaturesOptimal product design. Adoption of computer-aided design
(CAD SolidWorks ).Applicable to all general-purpose refrigerants
and non-corrosive gases and liquids, including ammonia, fluorine,
propane and propylene. Perfect sealing performance. The moving
part valve stem is provided with high-precision double O-ring and
PTFE packing to ensure zero leakage. All sealing gaskets are
environment- friendly asbestos-free ones that are resistant to both
fluorine and ammonia. The back seal design enables convenient
valve maintenance during system operation. The double-cone seal
design ensures large flow capacity, small pressure drop and high
efficiency.A special linkage structure between valve stem and valve
clack is adopted so that the concentricity of valve clack is
adjusted automatically to ensure valve closing tightness and
minimize valve clack friction for prolonging service
life. Compact structure, small size and light weight. Reducing
freight cost, shortening installation time and lowing labor
intensity.Best protection against rusting and corrosion. Special
rust-proof materials are used on the surface. The internal and
external surfaces are treated with special formula and process to
ensure cleanness and rust-free. The stainless steel valve stem is
polished by a special technique. Possibility of direct
welding to steel pipe or brazing to copper pipe. Customer options
are offered for either hand-wheel or sealed cap.Each valve is
inspected strictly according to European
standards. ApplicationThe valve is equipped with a check
valve mechanism and a stop valve mechanism, which allows the fluid
to flow in one direction while preventing backflow in the opposite
direction. The valve can be operated manually or actuated by a
pneumatic or electric actuator, depending on the specific
application requirements.The High Quality Straight Through Stop
Check Valve is widely used in various industries, including oil and
gas, chemical, petrochemical, and power generation, for fluid
transportation and storage applications. It meets international
standards for quality and safety, ensuring reliable and efficient
operation in harsh and demanding environments. Detailed
