EPDM Female Check Valve for positive & negative pressure
The CHIBIN female check valve, equipped with an EPDM O-ring, is designed for both positive and negative pressure applications, including vacuum pump systems, to effectively prevent backflow. The EPDM O-ring is ideal for industrial water cooling systems and can handle positive pressures up to 280 psi (20 kg/cm²).
This valve features a spring-loaded mechanism and female threaded connections on both ends. It allows fluid to flow in one direction only, protecting pumps, instruments, and other equipment from reverse flow.
The valve body is available in SUS304 or SUS316 stainless steel, depending on application and corrosion resistance requirements. The standard sealing material is a Viton O-ring, ensuring reliable sealing performance.
Features
- Suitable for positive & negative pressure applications.
- Vacuum pump systems to prevent backflow.
