Thermostatic valve, straight, LX insert, with preset, 3/4 inch, internal thread, with radiator connection with metal-to-metal seal V2020DLX20

Thermostatic valve for precise heating control

This thermostatic valve with LX insert and 3/4 inch internal thread is a reliable solution for regulating heat flow in heating systems. Designed for both professional installers and end-users, it provides thermal comfort and energy efficiency. Equipped with a radiator connection with metal-to-metal seal, it guarantees a leak-proof and durable connection.

This valve is particularly recommended for two-pipe heating systems where precise flow control is crucial for the optimal operation of the entire installation. The pre-setting option allows you to adapt the valve characteristics to the specific needs of a room or heating circuit.

Construction and application

The valve is characterized by a simple construction, which facilitates its assembly and servicing. Made of brass with a nickel-plated surface, it is corrosion-resistant and ensures long-term reliability. The LX insert allows cooperation with a wide range of thermostatic heads, giving you full control over the room temperature. The flow rate from 20 to 235 l/h at a pressure drop of 10 kPa makes the valve suitable for both small and large radiators.

• Purpose: two-pipe heating systems
• Material: brass with nickel plating – ensures corrosion resistance and durability
• Thread: 3/4 inch internal – standard connection for easy installation
• Connection: to radiator with metal-to-metal seal – guarantees leak-proofness and durability
• LX insert: compatible with various thermostatic heads
• Pre-setting: allows precise adjustment of the valve characteristics to the needs of the installation

Advantages and design features

This valve stands out with several important features:

• Precise regulation: thanks to the pre-setting option, you can optimize the heat flow in each heating circuit.
• Durability: the brass housing with nickel plating ensures corrosion resistance and long-term reliability.
• Leak-proofness: the connection with a metal-to-metal seal eliminates the risk of leaks.
• Versatility: compatible with various thermostatic heads.
• Dust protection: a dust cover protects the valve mechanism from dirt.
• Kvs value is 1.08 - an important parameter when selecting a valve for a specific heating system.
• Kv value range is from 0.063 to 0.74 - allows precise adjustment of the flow to the needs of the installation.
• Connection length is 37 mm and 74 mm - makes it easier to adapt to the existing installation.

This valve is thermostatically adapted (thermostatic valve size M30 x 1.5), which means its full compatibility with standard thermostatic heads available on the market. Additionally, the independence from pressure means that its operation is stable regardless of the working conditions in the installation.
