Thermostatic valve, angled, SX insert, with pre-setting, DN15, external thread 3/4 inch, with radiator connection with metal-to-metal seal V2026ESX15

Thermostatic valve for precise heating control

This angular thermostatic valve with SX insert is a key component in heating systems, designed for efficient heat flow regulation. Intended for both new installations and modernization of existing ones, it provides thermal comfort and optimizes energy consumption. Made of nickel-plated brass, it guarantees durability and corrosion resistance.

The valve is compatible with two-pipe heating and cooling systems, and its versatility allows for installation on both the supply and return of the radiator. Quiet operation in both flow directions is an additional advantage, especially in living spaces. The use of a metal-to-metal seal ensures a tight and reliable connection to the radiator.

Functionality and benefits for installers and users

The V2026ESX15 valve stands out for its ability to precisely regulate flow using an adjustment key. Limiting the maximum flow to 130% of the nominal value helps maintain system balance even with large temperature differences in individual rooms. The ability to replace the insert without emptying the installation significantly simplifies servicing and repairs – saving time and labor costs.

• Wide flow range: easy adjustment tailored to individual heating needs.
• Quiet operation: comfortable use without unwanted noise.
• Durable construction: brass body with nickel plating ensures corrosion resistance and long life.
• Easy insert replacement: minimizes installation downtime during servicing.
• Compatibility: works with various types of thermostatic heads (M30 x 1.5) and Honeywell Home actuators (HR90, HR91/HR92, MT4, M5410, M4410E/K, M7410E5001).
• Overflow protection: maintains hydraulic balance in the installation.
• Versatility: can be installed on the supply or return of the radiator.

Technical specifications and application

The valve has a 3/4 inch external thread and a 1/2 inch connection on both the pipe and radiator sides. Its flow rate ranges from 20 to 170 l/h at a pressure drop of 10 kPa, and the Kvs value is 0.7. It is adapted to work with thermostats of size M30 x 1.5. Thanks to the possibility of pre-setting, the valve characteristics can be precisely adapted to the specifics of a given room and heating system. The valve also has a dust cover to increase durability and is adapted for reverse flow direction, which increases installation flexibility. The manufacturer's warranty is 5 years from the date of manufacture, which confirms the high quality of the product.
