Straight 1/2 inch radiator shut-off valve ZP2YW

Radiator valve – reliable shut-off in the heating system

This simple shut-off radiator valve with a diameter of 1/2 inch is a basic element of every heating installation. It is used to precisely cut off the supply of hot water to individual radiators, allowing for their maintenance, replacement or adjustment without having to shut down the entire system. Made of brass, it ensures durability and corrosion resistance, which translates to a long service life.

This valve is particularly useful during servicing of the installation – it allows for safe and controlled isolation of a specific radiator. This allows the installer to focus on repair or replacement without disrupting the operation of the rest of the system. For the end user, this means the ability to easily resolve problems with a single radiator without having to involve a specialist in every case.

Design and operating parameters

The valve has been designed with ease of installation and reliable operation in mind. The body made of brass CW671N guarantees strength and resistance to high temperatures and pressure (up to 10 bar). Double sealing of the stem with an EPDM o-ring minimizes the risk of leaks, ensuring tightness and safety of use. An EPDM conical seal further improves the tightness of the connection with the radiator.

The valve is adapted to work with water and glycol-water solutions (up to 50%), which makes it a universal solution for various types of heating installations. The flow rate of 0.305 m³/h ensures an adequate flow of hot water, and the maximum operating temperature of up to 100°C allows it to be used in standard central heating systems.
