Brass Check Valve with Disc 1" — Perfexim (04-020-0250-000)

The Perfexim Brass Check Valve with Disc 1" is a one-way flow control valve designed to prevent backflow in piping and pump systems. Constructed with a brass body and a disc (poppet) closure, the valve is intended for use with water and other compatible liquids in domestic and light industrial applications. Its 1" connection size fits common piping arrangements for heating circuits, pump discharge lines and general plumbing where reliable one-directional flow is required.

Advantages

The brass construction offers corrosion resistance and mechanical durability suitable for typical potable water and heating system conditions. The disc (poppet) design provides a compact, low-profile closure that responds quickly to flow changes, helping reduce pressure drop and water hammer compared with heavier swing-type check valves. The 1" connection size allows straightforward integration into standard pipework and pump outlets.

Suitable for

• Domestic plumbing systems and household water lines
• Heating circuits and central heating pump discharge
• Light industrial piping with compatible liquids
• Booster pump outlets and circulation loops

Key specifications

• Body material: brass
• Closure type: disc (poppet)
• Connection size: 1"
• Intended media: water and compatible liquids
• Typical application: one-way flow prevention in plumbing and pump lines

How to use

Install the valve in-line with the flow direction indicated on the valve body, ensuring the disc faces the outlet side to prevent backflow. Use appropriate pipe fittings and sealing methods for brass connections, and tighten to recommended torque to avoid thread damage. Before commissioning, flush the line to remove debris that could impede the disc operation. Verify correct operation by running the system and checking for free flow in the forward direction and no detectable reverse flow when pumps are stopped.

Usage recommendations

To maintain reliable performance, avoid installing the valve where suspended solids or aggressive chemicals may contact the brass body or disc. Periodically inspect for buildup or wear and ensure the valve remains aligned with the piping. For systems subject to frequent water hammer or high pulsation, consider additional damping methods such as air chambers or surge protection.
