Product Description
Product Description
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.
