Thermostatic radiator valve set FERRO ZTM31BL, angled, black

FERRO ZTM31BL is an angled thermostatic radiator valve set in a black finish designed to regulate radiator temperature reliably. The set provides thermostatic control for maintaining a selected room temperature by modulating the flow of hot water through the radiator. The angled configuration is suitable for typical wall-mounted radiator connections and the black finish offers a discreet, modern appearance that integrates with contemporary interiors.

Advantages

The thermostatic mechanism enables automatic temperature regulation, reducing the need for manual adjustments and helping to maintain consistent comfort levels. The angled design facilitates easy connection to radiators with side supply lines and simplifies installation in tight wall spaces. The black surface is resistant to visible staining and pairs well with dark fixtures, providing a uniform look. Components are designed for compatibility with common radiator systems and for smooth valve operation.

Suitable for

• Residential panel and column radiators with angled side connections
• Commercial spaces where individual radiator temperature control is required
• Renovation projects seeking a coordinated black hardware finish
• Rooms where automatic thermostatic regulation improves energy efficiency

Key specifications

• Type: angled thermostatic radiator valve set
• Finish: black
• Function: thermostatic temperature control by modulating flow
• Connection orientation: angled (90°) for side radiator inlets
• Application: hot water central heating systems for room temperature control

How to use

Install the valve set on the radiator supply and return connections according to the radiator and pipework layout, ensuring angled orientation matches the inlet/outlet positions. After installation, attach a compatible thermostatic head (if not integrated) and set the desired temperature using the head’s scale. The valve will open or close proportionally to maintain the set temperature; occasional manual adjustments may be used to fine-tune comfort levels. Commission the system by bleeding radiators and checking for leaks, then verify correct operation across the heating cycle.

Usage recommendations

For reliable performance, use the valve in systems with clean, treated heating water and follow recommended installation practices, including use of appropriate sealing materials and tightening torques. Periodically check for smooth operation and absence of leaks; remove air from the system after fitting. If replacing an existing valve, confirm thread sizes and connection types before purchase to ensure compatibility with your radiator.
