Stainless Steel Threaded Swing Check Valve
Main Features
Excellent Material: The main components such as the valve body and disc are usually made of 304 or 316 stainless steel, which has outstanding corrosion resistance and high-temperature resistance and can adapt to various harsh working conditions.
Reasonable Design: It adopts a full bore design. When fluid passes through, it has low resistance and large flow rate, improving the operating efficiency of the system. The sealing performance between the disc and the seat is good, and it can achieve automatic closure under zero pressure, ensuring the reliability of the seal.
Flexible Installation: The threaded connection makes its installation and disassembly very convenient. It can be installed horizontally or vertically with strong adaptability and can meet the needs of different pipeline layouts.
Easy Operation: It doesn't require external power or manual operation. It relies entirely on the fluid's own pressure to achieve automatic opening and closing, with low maintenance costs.
Wide Application Range: It is applicable to various media and working conditions, such as in the water treatment, petrochemical, food processing, pharmaceutical and other industries. The working pressure range is generally 150 PSI to 2000 PSI, and the working temperature range is usually -20 °F to 797 °F.
Technical Specifications
Size Range: 1/4" ~ 4" (DN6~DN100)
Pressure Rating: 150 LB ~ 2500 LB (PN20 ~ PN420)
Connection Method: Threaded connection, conforming to ANSI B1.20.1 (NPT) or other relevant standards.
Material: The valve body and main components are usually made of stainless steel materials such as CF8 and CF8M.
Sealing Material: Stainless steel, polytetrafluoroethylene (PTFE) or other corrosion-resistant materials can be used.
Testing Standard: Strict inspection and testing are carried out in accordance with international standards such as API 598 to ensure product quality and performance.
Application Areas
Stainless steel threaded swing check valves are widely used in the following fields:
Water Treatment Systems: Prevent water backflow and protect pumps and pipelines.
Petrochemical Industry: Used for transporting oil products, chemical media, etc., to prevent safety accidents caused by medium backflow.
Food Processing and Pharmaceutical Industries: Ensure the one-way flow of fluid and avoid pollution and cross-infection.
HVAC Systems: Used in hot water and cold water circulation systems to prevent medium backflow.
Natural Gas and Steam Systems: Prevent gas or steam backflow and ensure the safe operation of the system.
Installation and Maintenance
Before Installation: Check whether the inside of the valve is clean and make sure there is no impurity blocking the disc. Check whether the threaded connection is in good condition, without damage or burrs.
During Installation: Pay attention to the flow direction mark on the valve and make sure the fluid flow direction is consistent with the mark. When installing, tighten the threads, but avoid excessive force that may cause damage.
Maintenance: Regularly check the sealing performance of the valve and the flexibility of the disc. If there is any abnormality, repair or replace the components in time. For valves that have been out of service for a long time, drain the internal fluid and conduct appropriate maintenance.
