For ladders

This category includes dynamic thermostatic valves designed for integration with ladder systems in heating and plumbing applications. These three-axis valves provide automatic temperature regulation and dynamic flow balancing to maintain consistent performance across the system. Available in configurations for steel, copper, and plastic pipe connections, they are suitable for use in radiant heating systems and underfloor heating installations.

Valves are manufactured from nickel-plated brass (CW617N) and operate at a maximum temperature of 120°C with a PN rating of 10. The head connection is standardised at M30 x 1.5 for compatibility with standard control heads. Options include preset Kv values for flow pre-setting and specific thread types for different pipe materials.

How to choose

• Select the appropriate thread type (L, P, or EK) based on the pipe material (steel, copper, or plastic) and connection method.
• Confirm the required Kv value for flow pre-setting to match system design requirements.
• Ensure compatibility with the control head by verifying the M30 x 1.5 thread size.
• Choose left-hand or standard threading based on installation orientation and space constraints.
• Verify the PN 10 pressure rating and 120°C temperature limit are suitable for the application.

Frequently asked questions

Can these valves be used with copper or plastic pipes?
Yes, valves with EK connections are compatible with copper or plastic pipes when used with the appropriate clamping screws (IVAR.TR, IVAR.TA, or IVAR.TP).

What is the function of the preset Kv value?
The preset Kv value allows for initial flow setting, ensuring the valve delivers the correct flow rate without manual adjustment during installation.
