For ladders

This category includes thermostatic double control valves designed for installation on ladder-style radiators. These three-axis valves are suitable for use in heating systems where precise temperature control is required. They feature a pre-settable Kv value and are compatible with steel, copper, and plastic piping via IVAR.TR, TA, and TP clamping fittings. The head connects via M30 x 1.5 threads, and the body is constructed from nickel-plated brass CW617N for durability and corrosion resistance.

Available in left and right configurations (L and P), these valves are intended for installation on the corresponding side of the radiator to ensure correct flow direction. They operate at a maximum temperature of +120°C and pressure rating PN10, making them suitable for standard central heating applications.

How to choose

• Confirm the required flow rate by checking the pre-settable Kv value to match the radiator’s heat output.
• Select the correct connection type (steel, copper, or plastic) and corresponding clamping fitting (IVAR.TR, TA, or TP).
• Choose the correct orientation (left or right) based on the position of the valve on the radiator.
• Verify that the head thread (M30 x 1.5) is compatible with your thermostat or control head.
• Ensure the material (nickel-plated brass CW617N) is suitable for the system environment.

Frequently asked questions

Can these valves be used with plastic piping?
Yes, they are compatible with plastic piping via TP clamping fittings as specified.

What is the maximum operating temperature?
The valves are rated for a maximum temperature of +120°C.

How do I determine the correct orientation (left or right)?
The left (L) or right (P) configuration refers to the side of the radiator where the valve should be installed to ensure correct flow direction.
