Perfexim angled non-return anti-corrosion check valve A.PHA-013 1/2" (1/2 WW)

The Perfexim angled non-return anti-corrosion check valve A.PHA-013 1/2" (1/2 WW) is an angled check valve engineered for threaded 1/2" water connections. It is treated for corrosion resistance and prevents reverse flow in potable water and heating systems. Constructed for domestic and light commercial plumbing, this valve fits inline at right angles to piping runs and is intended to protect pumps, boilers, meters and other hydraulic components from backflow.

Advantages

This angled non-return valve features an anti-corrosion surface treatment that extends service life in wet environments. The right-angle design allows installation in confined spaces where straight valves would be impractical. Its threaded 1/2" connections provide compatibility with standard plumbing fittings, while the internal seat and spring arrangement ensure reliable one-way flow and reduced water hammer compared with unrestrained fittings.

Suitable for

• Domestic potable water systems
• Heating circuits and radiator return lines
• Protection of pumps and valves from reverse flow
• Light commercial plumbing installations

Key specifications

• Connection type: threaded 1/2" (1/2 WW)
• Orientation: angled (right-angle) body
• Function: non-return (check) valve to prevent backflow
• Surface treatment: anti-corrosion coating
• Typical installation position: inline with flow direction mark oriented correctly

How to use

Install the valve in the pipeline with the arrow or flow direction marking pointing downstream to allow forward flow and block reverse flow. Use appropriate thread sealant or tape on the male threads to ensure a watertight connection. Tighten the valve with suitable tools without applying excessive torque to avoid damaging threads or the valve body. After installation, pressurize the system and check for leaks and correct operation by observing that fluid flows in the intended direction and that there is no reverse flow when the system is idle.

Usage recommendations

For reliable performance, install the valve where it is accessible for inspection and maintenance. Avoid installing the valve in locations where debris can accumulate; consider adding a strainer upstream if particulate contamination is possible. Periodically inspect seals and connections for corrosion or wear and replace the valve if leakage or impaired one-way function is detected.
