Radiator valve ARCO M30 straight 1/2" x 1/2"

Straight radiator valve ARCO M30 1/2" x 1/2" is a compact inline valve designed to control the flow of hot water to panel and column radiators. The valve fits systems that use M30 thermostatic heads and standard 1/2" threaded radiator connections, providing a simple solution for both replacement and new installations where a straight connection is required. Constructed for routine heating system use, the valve enables regulation of radiator supply to maintain desired room temperatures when paired with a compatible thermostatic head or used as a manual control.

Advantages

The ARCO M30 straight valve offers a compact, space-saving design and straightforward installation thanks to standard 1/2" threaded connections. Its compatibility with M30 thermostatic heads allows precise temperature control when a head is fitted, while the straight inline configuration minimizes piping complexity. The valve body is engineered for durability under normal hot water heating conditions and provides reliable operation for both replacement and new system applications.

Suitable for

• Panel radiators with 1/2" threaded inlets
• Column radiators requiring a straight valve connection
• Replacement of worn or leaking straight radiator valves
• New hot water heating installations using M30 thermostatic heads

Key specifications

• Connection size: 1/2" x 1/2" (threaded)
• Valve type: straight inline radiator valve
• Thermostatic head interface: M30 compatible
• Application: hot water central heating systems, panel and column radiators
• Typical materials: corrosion-resistant metals suitable for heating circuits

How to use

Shut off the heating system and drain the radiator before removing the existing valve. Fit the ARCO M30 straight valve into the radiator inlet using the 1/2" threaded connections, ensuring proper sealing with appropriate thread sealant or PTFE tape. Tighten connections to the manufacturer-recommended torque and refill the system, venting air from the radiator and checking for leaks. If temperature control is required, mount a compatible M30 thermostatic head onto the valve spindle following the head manufacturer's instructions.

Usage recommendations

Use the ARCO M30 straight valve in systems with matching 1/2" connections and combine with a certified M30 thermostatic head for automatic temperature regulation. Perform routine visual checks for leaks and ensure the valve is accessible for servicing; consult a qualified heating engineer for complex installations or where system compatibility is uncertain.
