Product overview

ZZWEP type temperature regulating valve maximum only ordinary 220V power supply, the use of the medium itself was transferred directly to the energy, 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 of temperature wide 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

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
