Product information

Description

CALEFFI straight radiator shut-off valve 3/4" is a compact isolation and control component for hydronic heating systems. Designed for mounting on radiator supply or return connections, the valve allows individual radiators to be shut off for maintenance, replacement or balancing without draining the whole system. The straight configuration suits installations where the pipe run aligns directly with the radiator connection. The valve is manufactured to industry standards and intended for residential and light commercial heating circuits.

Advantages

The valve provides reliable on/off control and precise isolation of individual radiators, reducing the need to interrupt the entire heating system during service. Its straight body simplifies installation on inline pipework and helps maintain system balance when used with other control devices. Robust construction and compatibility with standard 3/4" radiator fittings ensure long service life and easy replacement when required.

Suitable for

Isolation of individual radiators in hot water heating systems
Shutting off radiators for maintenance, repair or replacement
Balancing flow between radiators during commissioning
Residential and light commercial heating installations

Key specifications

Connection orientation: straight (inline)
Connection size: 3/4" suitable for standard radiator fittings
Function: shut-off / isolation valve for radiator circuits
Application: hydronic hot-water heating systems
Typical materials: corrosion-resistant metal body and sealing elements suitable for heating fluids

How to use

Install the valve in the radiator supply or return line in the orientation matching the straight connection. Tighten connections according to pipework material and installation practice, using appropriate sealing methods for the thread type. Operate the valve to close the flow before starting maintenance or replacement of the radiator; when work is complete, slowly open the valve and check for leaks. Follow local plumbing and heating regulations and bleed the radiator to remove trapped air after reassembly.

Usage recommendations

Use the valve together with compatible fittings and control components; inspect seals and joints after initial operation and during periodic maintenance. If the system contains aggressive fluids or operates outside normal domestic temperature/pressure ranges, consult system documentation or the manufacturer for material compatibility.
