Product Description

Self Operated Heating Temperature Regulator Valve


Self operated control valve Product Introduction

Self operated control valve composed of a body, an actuator with temperature sensor. 
ZZWT series works by the energy of the medium heating.
The valve realize automatic adjustment by using the principle of liquid expansion and liquid incompressibility when heated.The liquid expansion in the temperature sensor is uniform, and its control function is proportional regulation.
When the temperature of the controlled medium changes, the volume of the temperature sensing liquid in the sensor expands or contracts.
When the temperature of the controlled medium is higher than the set value, the temperature-sensitive liquid expands and pushes the spool down to close the valve to reduce the flow of the heat medium.
When the temperature of the controlled medium is lower than the set value, the temperature sensing liquid body contracts, and the reset spring pushes the spool to open, increasing the flow of the heat medium.
Temperature control valve is suitable for all kinds of gas, steam, hot water, oil as the medium of a variety of heat exchanger temperature automatic control. It has the advantages of wide temperature setting range, convenient adjustment, continuous temperature setting, over-temperature and over-plant protection, convenient temperature setting, etc.
Widely used in city heating, heating system and electric power, petroleum, metallurgy, pharmaceutical, boiler and other industrial sectors.
