Check Valve Purmo V09001 1/2" (RS-ZAWÓR ZWROTNY VENTO 1/2)

Purmo check valve V09001 1/2" is an inline non-return valve designed to prevent reverse flow in heating and potable water systems. The valve features a compact brass body and standard threaded connections for straightforward insertion into existing pipework. It is intended to maintain one-way flow, protect pumps and systems from backflow, and support stable operation of radiators and boiler circuits.

Advantages

The brass construction provides corrosion resistance and mechanical durability while retaining a small footprint for installation in confined spaces. Threaded connections enable quick fitting without special adapters, and the internal non-return mechanism offers dependable sealing to avoid reverse flow. The product's design suits common residential plumbing and heating layouts, delivering consistent directional flow control.

Suitable for

• Domestic radiators and heating circuits
• Boiler return or feed lines to prevent backflow
• General water distribution and circulation systems
• Pump protection in small heating and domestic installations

Key specifications

• Connection size: 1/2" threaded
• Body material: brass
• Operational function: non-return (check) valve for one-way flow
• Installation type: inline, suitable for horizontal or vertical pipe runs depending on system layout
• Typical applications: heating and potable water systems in residential settings

How to use

Install the valve in the pipework according to the flow direction marked on the body, ensuring the arrow points toward the downstream side. Use appropriate sealing tape or thread sealant on the male threads to ensure leak-free joints. Tighten the valve with suitable tools without over-torquing to avoid damaging the brass threads. After installation, pressurize the system and check for leaks and correct one-way operation before returning the system to normal use.

Usage recommendations

Select the valve placement to allow periodic access for inspection and possible service. Avoid installing the valve where solid debris or excessive particulate can accumulate; incorporate appropriate strainers or filters upstream if necessary. Follow local plumbing and heating regulations and use compatible thread sealants for potable water systems.
