## Long description

Perfexim brass check valve with mushroom disc, size 3/2", is a unidirectional valve designed to prevent backflow in liquid systems. Constructed from brass with a mushroom-shaped disc, it provides compact, corrosion-resistant performance for plumbing, heating and water supply installations. The valve is intended for domestic and light commercial applications where a reliable one-way flow control component is required.
Advantages
The brass body offers corrosion resistance and mechanical strength while remaining compact for installation in confined spaces. The mushroom disc design provides positive sealing and straightforward operation with minimal pressure drop across the valve. Solid construction and simple internal geometry reduce maintenance needs and support long-term, reliable performance in potable water and heating circuits.
Suitable for
 Domestic plumbing systems to prevent backflow
 Central heating circuits and boiler installations
 Water supply lines in residential and light commercial buildings
 Pump discharge lines where one-way flow is required
Key specifications
 Valve type: unidirectional check valve with mushroom (disc) closure
 Material: brass body and internal components suitable for water service
 Connection size: 3/2" nominal thread size for standard plumbing fittings
 Design: compact inline body for installation in tight spaces
 Application medium: cold and hot water, heating fluids compatible with brass
How to use
Install the check valve in-line with the flow direction indicated by the valve orientation; ensure threads and sealing surfaces are clean and use appropriate thread sealant or tape compatible with potable water systems. Tighten to recommended torque for the connection material to avoid distortion. Verify correct operation by pressurizing the system and observing that the valve allows flow in the intended direction while preventing reverse flow. Periodically inspect for leaks, secure fittings, and any signs of wear or buildup.
Usage recommendations
For optimal performance, select the valve size matching existing pipework and maintain accessible installation for inspection. Avoid installing the valve near sources of heavy sediment without upstream filtration, and perform routine checks in heating systems to prevent debris accumulation that could impair the mushroom disc seal.
