Product Description

 

ZZWP Self-operated temperature control valve Overview:
Self-operated temperature regulating valve is mainly composed of control valve and thermostat, is a kind of energy saving products without external energy and rely on the temperature change of the controlled medium itself to automatically adjust. Has a wide range of temperature setting, clear display, high precision, and is equipped with overload protection device, safe and reliable, so widely used in chemical, petroleum, electric power, metallurgy, food, textile, residential buildings, hotels, restaurants and other heating, water supply, refrigeration, sterilization and other equipment temperature automatic regulation.
The nominal diameter of this series of products is from 20 to 200mm, the nominal pressure is 1.0, 1.6, 4.0, 6.4MPa, the temperature range of Mingke valve is from -20 ° C to 350 ° C, and the signal is 0~10mA.DC or 4~20mA.DC to change the flow rate of the adjusted medium, so that the controlled process parameters are maintained at the given value. The single-seat adjustment type is suitable for small pressure difference, large medium viscosity or slightly granular impurities. Sleeve regulating type is suitable for large pressure difference occasions.
