Stop Valves
1. Technical Parameters:
Nominal pressure: 4.0MPa Test pressure: 6.0MPa
Applicable temperature: -50ºC ~ +150ºC
Applicable medium: ammonia, fluorine, propane,propylene, etc.
2. Application:
Welding right-angle stop valves are widely used in refrigerated-storage and freezing systems in the industries of cooling, refrigeration and air-conditioning as well as the industries of food, beverage, bear, pharmaceutical, ship-building, gas, chemical, petroleum, etc.
3. Advantage:
Refrigeration stop valves are featured by good-looking and artistic appearance, advanced and unique structure, light and flexible operation, excellent sealing performance, zero leakage, high reliability and long service life.
3. Feature:
Optimal 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.
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 ensurecleanness 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.
