## Long description

Perfexim brass check valve with a mushroom (disc) seat, connection size 3/4". This inline non-return valve is designed to allow fluid flow in one direction while preventing backflow in plumbing and heating systems. The valve is made from durable brass and features a compact body with a mushroom-style internal seat that provides reliable sealing and reduced hydraulic resistance. It is suitable for potable water systems, central heating circuits and pump protection where a simple, space-saving check valve is required.
Advantages
The brass construction ensures corrosion resistance and long service life in typical domestic and light-commercial installations. The mushroom (disc) seat offers predictable sealing performance and lower noise during operation compared with some spring-only designs. Inline form factor enables straightforward installation in existing pipe runs, and the 3/4" connection size covers common residential plumbing and heating applications.
Suitable for
 Potable water supply lines
 Central heating circuits and radiators
 Pump discharge lines for backflow protection
 Compact or retrofit installations with limited space
Key specifications
 Body material: brass
 Internal seat type: mushroom / disc seat
 Connection size: 3/4" (inline)
 Installation orientation: inline, flow direction must be observed
 Typical applications: potable water, heating systems, pump protection
How to use
Install the valve in-line with the direction of flow indicated on the body. Ensure compatible pipe fittings and sealing materials are used for the 3/4" connections and that the system is depressurized before installation. Tighten connections to the torque recommended for brass fittings to avoid distortion. After installation, slowly pressurize the system and check for leaks and proper one-way operation by observing flow and verifying there is no backflow when downstream pressure is applied.
Usage recommendations
For reliable long-term performance, install the valve in accessible locations for inspection and occasional maintenance. Use water with appropriate quality for brass components and avoid aggressive chemicals. If used in heating systems, consider system flushing prior to installation to remove debris that could impair the seat sealing.
