V2 / V4 / V8 Self-Acting Thermostats

The temperature controller, which consists of a thermostat and a valve, is used to control the temperature in central heating systems, district heating systems, industrial plants or industrial processes, and marine systems. The Clorius V2 / V4 / V8 Self-Acting Thermostats can be used to control cold or hot water, steam or oil in heating and cooling systems.

Thermostat

A thermostat consists of a sensor and a capillary tube, fi filled with liquid, and an adjusting cylinder. The thermostat type designations and technical data are specifi ed in fi g. 2. With temperatures above 170ºC, a cooling unit must be fi fitted between the valve and the thermostat – see fi g. 1. The thermostat is self-acting and works on the principle of liquid expansion, it is sturdy in its design, and works with a large closing force – see fi g. 2
Sensor

The following sensor types are available:

• Rod sensor in copper or stainless steel and spiral sensor in copper with threaded connection according to ISO R7/1.
• Spiral sensor (copper only) with air duct flange.
• Rod/spiral sensor with steel flange DN 50, PN 40 and DN 50, PN 160.
• Sensor without connection. Usually used with capillary pack box for temperature control in tanks.

Capillary Tube
The capillary tube is made of copper, stainless steel, or PVC-coated copper but can also be delivered with flexible iron tube protection.
