Radiator valve Valvex straight 1/2 x 3/4" model 1480030

Valvex straight radiator valve model 1480030 with connection sizes 1/2 x 3/4" is a manual control valve designed for use in central heating radiator installations. It provides a straightforward means to regulate flow to a radiator, offering compatibility with radiators and piping that require a 1/2" to 3/4" straight connection. The valve is intended for both replacement of existing valves and installation in new systems where these thread sizes and a straight configuration are needed.

Advantages

The valve offers reliable manual flow regulation with a compact straight design that simplifies alignment between radiator and pipework. Its construction is optimized for central heating environments, providing stable operation and easy mechanical adjustment without electrical components. The connection sizes ensure wide compatibility with standard radiator fittings that use 1/2" and 3/4" threads.

Suitable for

• Replacement of worn or leaking radiator inlet valves with matching 1/2" x 3/4" connections
• New radiator installations requiring a straight valve between pipework and radiator
• Central heating systems where manual flow control is preferred
• Domestic and light commercial radiator setups using standard threaded fittings

Key specifications

• Valve type: straight radiator valve
• Connection sizes: 1/2" x 3/4" (threaded)
• Operation: manual flow regulation
• Application: central heating radiator inlet
• Compatibility: standard radiator fittings using the specified thread sizes

How to use

Install the valve in the radiator inlet line ensuring the 1/2" and 3/4" threaded connections match the pipe and radiator fittings. Isolate and drain the section of the heating system before removing the old valve. Apply appropriate thread sealant or tape to the male threads if required by the installation practice, then tighten the connections to the recommended torque for the fittings. Once installed, refill and purge the radiator to remove trapped air, then adjust the valve by turning the control to achieve the desired flow and radiator temperature.

Usage recommendations

For safe and durable operation, use the valve within standard residential central heating temperature and pressure ranges and perform routine system maintenance. When replacing an existing valve, verify thread compatibility and, if unsure, consult technical documentation or a qualified heating installer to prevent leaks and ensure correct alignment.
