## Summary description

Angle radiator shut-off valve by Perfexim with double mushroom (double-seat) design and 1/2" female (GW) thread. Intended for use on heating radiators to isolate and regulate flow to individual units during installation, maintenance or replacement. The compact angle form suits corner connections on hot-water central heating systems and helps simplify radiator servicing.

## Long description

The Perfexim radiator shut-off angle valve with a double mushroom (double-seat) design and 1/2" female thread is a compact shut-off and flow-regulating valve for hot-water central heating radiators. Its angle configuration is designed for corner connections, allowing isolation of a single radiator during installation, maintenance or replacement without draining the entire system. The double-seat mechanism reduces leakage when the valve is closed and provides stable flow control when open.
Advantages
The double mushroom (double-seat) design improves sealing reliability and reduces the risk of seepage at the closed position. The compact angle body is suitable for tight installation spaces and simplifies connection to standard 1/2" radiator tails. The valve offers straightforward mechanical control of flow to individual radiators, enabling selective isolation and easier servicing. Durable materials and conventional thread dimensions ensure compatibility with common radiator fittings.
Suitable for
Individual radiator isolation in hot-water central heating systems
Corner-mounted radiator connections where space is limited
Radiator replacement or maintenance without emptying the whole heating system
Flow regulation to balance heating between rooms
Key specifications
Valve type: angle shut-off valve with double-seat (double mushroom) mechanism
Connection thread: 1/2" female (GW) standard thread for radiator tails
Application: hot-water central heating radiators
Functionality: isolation and manual flow regulation to a single radiator
Typical installation position: corner/angle connection to radiator inlet or outlet
How to use
Fit the valve to the radiator tailpiece using the 1/2" female thread, ensuring correct sealing with appropriate gasket or sealing tape where required. Turn the valve spindle to open or close flow to the radiator; clockwise movement typically closes the valve while counterclockwise opens it. Use the valve to isolate a radiator before performing maintenance or removal, and to adjust flow for balancing room temperatures. Ensure the system is depressurised or isolated locally where necessary before removing existing fittings.
Usage recommendations
Install and service the valve in accordance with local plumbing and heating regulations. Use compatible fittings and check for leaks after installation. Regularly operate the valve to prevent seizing in installations with infrequent use.
