Thermostatic valve, straight, FX insert, with pre-setting, 3/8 inch, internal thread, with radiator connection with metal-to-metal seal, long body V2000DFX10

Thermostatic valve for precise radiator control

This thermostatic valve with FX insert is a reliable solution for regulating heat flow in heating systems. Designed for two-pipe systems, it provides thermal comfort and energy efficiency. Thanks to its precise proportional characteristic, the valve works perfectly in low-flow installations, offering quiet operation and stable room temperature.

The valve has a 3/8 inch internal thread and a radiator connector with a metal-to-metal seal, guaranteeing a leak-proof and durable connection. The long body facilitates installation and access in tight spaces. The pre-setting option allows the valve to be adapted to individual needs and the characteristics of the installation.

Construction features and application

The V2000FX valve has been designed with ease of use and reliability in mind. Made of high-quality brass with a nickel-plated surface, it is resistant to corrosion and mechanical damage. Protected by a dust cover, it maintains cleanliness and efficiency for a long time. The ability to reverse the flow direction increases installation flexibility.

The valve is compatible with thermostatic heads with an M30 x 1.5 connection and Honeywell Home evohome, HR90 and HR91/HR92 controllers, as well as MT4 thermoelectric actuators and the M4410E/K and M7410E5001 series. Moreover, it is fully compatible with the Honeywell Home AT-Concept solution and thermostatic valves MNG, Honeywell and Honeywell Home produced since 1974 – this guarantees easy replacement and modernization of existing installations.

• Flow rate: 10 - 70 l/h (at a pressure drop of 10 kPa), allowing precise adjustment to the heat demand.
• Kv value range: 0.032 - 0.22 – a parameter important for plumbers when designing and balancing installations.
• Kvs value: 0.285 – additional information for hydraulics specialists.
• Insert replacement possible: without the need to drain the installation – saving time and costs during servicing.
• Keymark certificate (EN 215): confirmation of compliance with European safety and quality standards.

This valve is not only a regulating element, but also an investment in comfort and energy efficiency of the building. The proportional characteristic ensures smooth temperature control, and the limited maximum flow rate (up to 130% of the nominal flow) helps maintain balance throughout the heating system. A spring located outside the water space increases the valve's lifespan, and a double O-ring seal minimizes the risk of leaks. The manufacturer's warranty is as long as 5 years from the date of production!
