Safety valve, with capillary tube 1.3 m TS131-3/4A

Safety valve with capillary TS131-3/4A is a reliable protection for heating systems, especially solid fuel and mixed fuel boilers. Its operation is based on direct reaction to the temperature of the heating medium, providing effective protection against overheating and damage to the system. The construction of dezincification resistant brass (DZR) guarantees durability and corrosion resistance, and the capillary length of 1.3 meters provides flexibility in choosing the installation location.

This valve is designed for use in closed heating systems compliant with EN12828 standard. When a temperature of 95°C is reached, the valve automatically opens the water outlet, removing excess heat and preventing temperature increase. This solution is particularly important in boilers with a built-in water heater or a cooling coil. Thanks to this, the installation is protected against potential failures caused by excessively high temperature.

Key features and benefits:

• Fast reaction: Direct-acting valve starts immediately after exceeding the set temperature (95°C), minimizing the risk of damage.
• Durable construction: Made of dezincification resistant brass (DZR), ensuring long-lasting and reliable operation even in harsh conditions.
• Installation flexibility: Capillary length of 1.3 meters allows precise placement of the temperature sensor in the optimal location.
• Compliance with standards: Meets the requirements of PN-EN12828 standard, guaranteeing safety and efficiency.
• Versatility of application: Possibility of mounting both on the cold water supply in the heat exchanger and on the hot water outlet from the water heater.
• Efficiency: Maximum efficiency is 2800 l/h, ensuring effective removal of excess heat.

The valve has internal gas tapered BSPP-G (ISO 228-1) threads with a diameter of 3/4 inch on both connection side 1 and 2. The pressure class of the device is PN 10, and the maximum working pressure is 10 bar. The overall length is 62 mm, and the height is 98.5 mm – these dimensions facilitate integration of the valve into the existing installation. The immersion tube with a diameter of 1/2 inch and a length of 152 mm ensures precise measurement of the medium temperature. The maximum medium temperature (continuous) is 95°C, and the maximum ambient temperature is 40°C.
