Thermostatic valve, straight, SX insert, with preset, 1/2 inch, internal thread, with radiator connection with metal-to-metal seal, long body V2000DSX15

Thermostatic valve V2000DSX15 is a component used to precisely regulate the flow of hot water in heating systems. This is particularly important in systems with a circulation pump, where hydraulic balancing allows for optimal heat distribution to all radiators. Thanks to its design, this valve works well in both standard and reverse flow installations.

Design and application

The V2000DSX15 valve has a 1/2 inch internal thread, which simplifies its installation in existing systems. Made of brass, it ensures durability and corrosion resistance. The included radiator connector with a metal-to-metal seal guarantees a leak-proof and reliable connection. The long valve body makes it easier to install in tight spaces. The ability to pre-set allows you to limit the maximum flow, which is crucial for maintaining hydraulic balance in the system and preventing overheating of some rooms.

Advantages and benefits

• Versatility: Suitable for two-pipe systems, and can also be used on the supply or return of the radiator.
• Precise regulation: Allows accurate adjustment of heat flow, which translates into thermal comfort and energy savings.
• Quiet operation: Ensures comfortable use thanks to quiet operation in both standard and reverse flow directions.
• Durability: Made of brass with a nickel-plated surface, resistant to corrosion and mechanical damage.
• Easy installation: 1/2 inch internal thread and included connector simplify the installation process.
• Replaceable cartridge: In the event of a failure or the need to change the valve characteristics, only the cartridge can be replaced without disassembling the entire installation (service tool required).
• Compatibility: Works with various types of thermostatic heads (M30 x 1.5) and Honeywell Home actuators (HR90, HR91/HR92, MT4, M5410).

The valve is characterized by a Kv value range from 0.063 to 0.54, which allows for flow regulation in the range of 20 to 170 l/h with a pressure drop of 10 kPa. The nickel-plated surface protection further increases its resistance to external factors. It has a dust cover to protect against dirt. Thanks to the possibility of pre-setting, the maximum flow can be limited to 130% of the nominal flow - this is important for maintaining the hydraulic balance of the heating system even with large temperature differences in individual rooms.
