## Long 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.
