Angle stop valve

The 20-16-16 (Lockshield Valve) 3421 angle shut-off valve for radiators is a reliable component of a heating system designed to regulate and balance the flow of coolant within a radiator. It is used to connect and service radiators without the need to shut down or drain the entire heating system.

The valve allows for precise adjustment of the water supply to an individual radiator, ensuring a more even distribution of heat throughout the heating system. The device is also convenient for maintenance—if necessary, the radiator can be disconnected from the piping without interrupting the operation of the other heating circuits.

The model is typically equipped with a 1/2-inch threaded connection for connecting to the radiator, making the valve compatible with many standard heating systems. The nickel-plated brass construction ensures high strength, corrosion resistance, and a long service life even under constant exposure to hot water and temperature fluctuations.

Advantages of the angle shut-off valve:

heating system balancing;

ability to shut off a radiator without draining the system;

angle design for easy installation;

1/2" threaded connection;

nickel-plated brass body;

corrosion resistance;

tight and reliable connection;

suitable for residential and commercial heating systems.

The Lockshield Valve angle valve is a practical solution for the efficient adjustment, maintenance, and stable operation of a radiator heating system.
