The Brass Check Valve is an essential component in fluid systems to ensure unidirectional flow and prevent backflow, which could cause damage to pumps and other equipment. Made from high-quality brass (CW617N), it offers excellent corrosion resistance and is designed for use in various industrial, plumbing, and oil & gas applications.
The check valve automatically closes when flow reverses, protecting the system from potential damage. It is equipped with EPDM, NBR, or PTFE sealing rings to ensure a leak-tight seal. The valve is available in both flanged and threaded connection types, making it versatile for installation in different pipeline systems.
Ideal for water, oil, gas, and other non-corrosive fluids, this check valve is commonly used in plumbing, HVAC, water treatment, and oil & gas pipelines, where reliable, low-maintenance operation is required.
Features
- Compact and Durable: Constructed from brass (CW617N), this check valve offers corrosion resistance and durability in water, oil, and gas systems.
- One-Way Flow Control: The valve allows flow in one direction and automatically prevents reverse flow, protecting pumps and pipelines.
- Versatile Application: Ideal for plumbing, water treatment systems, HVAC systems, and oil & gas pipelines.
- Reliable Sealing: Equipped with reliable sealing materials like EPDM, NBR, or PTFE, the valve ensures a leak-proof seal.
- Flexible Connection Options: Available in both flanged and threaded configurations (BSP, NPT) to suit various installations.
- Wide Pressure Range: This valve is rated for PN10 or PN16 pressure systems, suitable for residential, commercial, and industrial applications.
- Lightweight and Easy to Install: The brass construction makes this valve easy to handle and install in various piping systems.
