Stainless Steel Screwed Vertical Check Valve
Main Features
Material Advantage: The main components such as the valve body and the valve disc are usually made of 304 or 316 stainless steel, which has excellent corrosion resistance and high-temperature resistance and can be applicable to various media, such as water, oil, steam, gas, etc.
Sealing Performance: Equipped with high-performance sealing materials like PTFE, it ensures that the valve can achieve reliable sealing under various working conditions.
Flexible Installation: It adopts threaded connection. The connection method is simple and the installation is convenient. It can be installed vertically upwards or horizontally as needed.
Reliable Operation: It automatically controls the opening and closing of the valve disc relying on the pressure of the fluid itself. It doesn't require external power, is easy to operate and has low maintenance costs.
Wide Application Range: It is applicable to multiple industrial fields, such as food processing, pharmaceuticals, chemical engineering, water treatment, HVAC (Heating, Ventilation, and Air Conditioning), etc., and can meet the requirements of different media and working conditions.
Technical Specifications
Size Range: 1/4" ~ 3" (DN6 ~ DN80)
Pressure Rating: 1.6 MPa ~ 6.4 MPa
Temperature Range: -20 °C ~ 180 °C
Connection Method: Threaded connection, conforming to standards such as NPT, BSPT or BSPP.
Application Areas
The stainless steel threaded vertical check valve is applicable to the following fields:
Food and Beverage Industry: It is used to prevent the backflow of liquids and ensure hygiene and safety during the food processing process.
Chemical Industry: It is used for transporting corrosive chemicals and preventing safety accidents caused by the backflow of media.
Water Treatment System: It prevents the backflow of water and protects pumps and pipelines.
HVAC System: It is used in hot water and cold water circulation systems to prevent the backflow of media.
Pharmaceutical Industry: It meets strict hygiene and aseptic requirements and is suitable for fluid control during the drug production process.
Installation and Maintenance
Before Installation: Check whether the inside of the valve is clean and make sure there is no impurity blocking the valve disc. Check whether the threaded connection is intact, 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 valve disc. If there is any abnormality, repair or replace the components in time.
