Thermostatic valve TA-THERM ZERO DN20 for DHW with thermometer +55°C 52820020

Thermostatic valve TA-THERM ZERO is a reliable solution for regulating the temperature of domestic hot water in circulating systems. This product, with a nominal diameter of DN20, is designed for energy efficiency and ease of use. Its construction based on an internal gas BSPP-G (ISO 228-1) threaded connection ensures the tightness and durability of connections.

Functionality and application

The TA-Therm ZERO valve is designed to automatically maintain the set water temperature in DHW installations, which translates to user comfort and reduced energy losses. The temperature adjustment range from 35 to 80°C allows for precise adjustment to individual needs. The built-in thermometer makes it easy to read the current temperature and monitor the valve's operation. Thanks to its C characteristic, the valve copes well with current loads occurring when starting devices such as pumps or heaters.

The valve finds application in:

• domestic hot water circulation installations in residential buildings,
• hotel and catering installations,
• underfloor heating systems (in combination with appropriate actuators),
• public buildings.

Construction and special features

TA-Therm ZERO is distinguished by its solid construction and the use of high-quality materials. Made of lead-free brass (<0.1% lead content), it meets stringent environmental standards and ensures safe use. The locking mechanism for settings prevents accidental adjustment of the valve, guaranteeing temperature stability. A Kvs value of 1.1 indicates an appropriate water flow while maintaining optimal pressure in the installation. The use of a thermometer directly on the valve body eliminates the need for additional measuring instruments, simplifying diagnostics and servicing of the installation. The working pressure PN 16 ensures safe operation under standard operating conditions.

This valve is particularly recommended for installers due to:

• easy installation thanks to the standard BSPP-G thread,
• precise temperature control,
• durable construction resistant to corrosion,
• lead-free – compliance with environmental requirements.

For end users, the advantages are:

• comfort of use thanks to stable water temperature,
• energy savings by reducing heat loss,
• durability and reliability of the device,
• easy temperature reading thanks to the built-in thermometer.
