Product information

Description

CALEFFI 1/2" straight radiator shut-off valve model 432402 is a manual inline isolating valve intended for use in central heating radiator circuits. The valve provides a straight, compact connection with a 1/2" nominal inlet and outlet suitable for standard radiator fittings. It is designed to allow reliable shut-off of flow to a radiator for maintenance, replacement, or system balancing without affecting the rest of the heating circuit.

Advantages

The straight design offers a compact installation profile and straightforward alignment with radiator tails and pipework. Manual operation enables quick isolation of a single radiator for service or adjustment. The valve body is manufactured to industry standards for heating system components, offering durability and consistent performance in residential and commercial applications. Its simple construction makes it easy to operate and maintain.

Suitable for

Isolating individual radiators in central heating systems
Maintenance and replacement of radiator bodies or valves
Balancing flow between radiators during commissioning or adjustment
Use in residential apartments, houses, and light commercial buildings

Key specifications

Connection type: straight inline with 1/2" nominal thread
Function: manual shut-off / isolating valve for radiator circuits
Application: central heating radiator installations
Mounting orientation: inline, straight connection
Operation: manual control for opening and closing flow

How to use

Shut off the flow to the radiator by turning the valve handle or spindle until the flow is stopped; the valve can be used to isolate the radiator for repair, replacement, or balancing. Before disconnecting any pipework, ensure the heating system is drained or the local section is depressurised according to standard safety procedures. After work is completed, reopen the valve slowly while checking for leaks and restore system pressure and balance as required.

Usage recommendations

Install the valve in accessible positions to allow manual operation and periodic inspection. Use appropriate sealing materials and follow manufacturer torque guidelines when connecting to radiator tails and pipework. During commissioning, operate the valve to confirm smooth movement and leak-free joints before leaving the system in service.
