Details
The H41H/W stainless steel lift-type check valve is strictly designed and manufactured according to the GB12235 standard. The valve disc moves vertically along a central guide, while the bushing is made from a special material that offers excellent wear resistance and features a low coefficient of friction, ensuring smooth and reliable operation with outstanding sealing performance. This product is widely used in pipelines across various industrial applications, including petroleum, chemical, pharmaceutical, and power industries.
The H41W-16/25/40/64P stainless steel lift check valve is designed for use in pipelines under various operating conditions—such as those found in petroleum, chemical, and thermal power plants—handling media like water, oil products, steam, and more. It is suitable for applications with nominal pressures ranging from PN1.6 to 6.4 MPa and operating temperatures between -29°C and 550°C.
Structural features:
1. Materials are carefully selected to meet relevant domestic and international standards, ensuring comprehensive high-quality performance.
2. The sealing pair is advanced and well-designed, with the valve disc and seat sealing surfaces fabricated by overlay welding using iron-based alloys or Stellite cobalt-based hard alloys, offering excellent wear resistance, high-temperature durability, corrosion resistance, and scuffing resistance—resulting in a long service life.
3. The products are designed and manufactured according to the national standard GB/T12235.
4. Various piping flange standards and flange sealing types can be employed to meet diverse engineering needs and user requirements.
5. The valve body materials are available in a complete range, and gaskets can be reasonably selected based on actual operating conditions or user requirements, making them suitable for a wide variety of pressure, temperature, and medium applications.
We can design and manufacture check valves with various structural and connection types according to customer requirements, making them suitable for use with a wide range of equipment.
