Description
30L01T01Y/R、30L01T02Y/R self-operated flow and temperature control valve
Summary
The30L01T01Y/30L01T0 1R 30L01T02Y /30L01Y02Rself-operated temperature control valve (cooling type) is composed of the control valve and a temperature controller provided with fixed point control. It is suitable for controlling temperature of non-corrosive liquids, gases and steams
in various cooling systems. When the temperature of the controlled medium rises, the control valve is opened.
The main features are as follows:
1.It has the pressure balancing function with high sensitivity.
2.Low noise, reliable performance, free of maintenance
3.The standard modular design is adopted.
4.The flow is adjusted according to the standard figure by the throttle valve, which is convenient and fast.
5.It adopts the imported fixed point controller, which has the over temperature protection function with reliable quality.
6.Various combined controls can be carried out through the assemblies.
