TS131

Temperature Relief Valve

With test facility and double sensor

Product specification sheet

Application

The TS131 temperature relief valve for heating systems accor­ding to EN 12828 is a self-acting valve which is activated by the
flow temperature of the heat generator. It opens and discharges
water from the heat generator or condensing coil at a flow tempe­rature of 95 °C and thereby prevents a significant temperature
rise in the heat generator.

Special Features

• Construction tested to EN 14597 (TH119507)

• Immersion pocket with double heat sensors

• Test facility

• Capillary tube protected against kinking by steel sheath

• Immersion pocket with external thread

Range of Application

Multi-fuel boilers with integral water heating or condensing coils
in closed solid-fuel fired heating systems to EN 12828.

Construction

The temperature relief valve comprises:

• Housing with internal thread

• Bonnet

• Valve piston with form seal

•Spring

• Remote double temperature sensor with capillary tube

• Immersion pocket G 1/2” (ISO 228)

Materials

• Brass housing, bonnet and immersion pocket

• Copper temperature sensor

• Copper capillary tube

• Brass valve piston

• Hot-water-resistant elastomer seals

Method of Operation

The temperature relief valve is actuated by the flow temperature
of the heat generator. It comprises a spring-loaded valve and a
bellows operated temperature sensor. When a boiler flow tempe­rature of 95ºC is reached the force exerted by the bellows system
becomes greater than the force of the spring and the valve
opens. Heated potable water then flows out and this is replaced
by cold water from the supply network.

This absorbs excess heat from the heat generator and prevents
overheating.
