A,ZZWEP type self operated electronic control temperature control valveProduct overview

Electronically controlled temperature self regulating valve (applies to the larger diameter and thermal oil control), the biggest characteristic of this valve only ordinary 220V power, the media's own energy to be transferred, directly to the steam, heat, oil and gas as the medium temperature automatic regulation and control, can also be used in preventing overheating or heat exchange on occasion the valve has the advantages of simple structure, convenient operation, selection, temperature range, fast response, reliable sealing performance, and can be in operation to adjust, so it is widely used in chemical, petroleum, food, textile, and other departments of the hotel and the hotel hot water supply

Two,ZZWEP type self operated electronic control temperature control valveProduct features

This series of products of nominal diameter from 20 to 200mm, 1, 1.6, nominal pressure 4 6.4MPa, the temperature range of ~350 DEG C by -20, 0~10mA.DC or 4~20mA.DC to accept the signal change by adjusting the media flow, make the controlled parameters to maintain a given value, the single seat control type suitable for low pressure difference, medium high viscosity or slightly granular impurities occasions. Sleeve adjustment type is suitable for occasions with large pressure difference
