Self operated temperature control valve
Self operated electronic temperature control by our factory independent research and development production of valves (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 to prevent overheating or heat exchange occasions, the valve has the advantages of simple structure, convenient operation, selection of 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.
Self operated temperature control valveNominal 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 is applicable to pressure difference is small, medium viscosity or a little impurity occasion. Sleeve adjustment type is suitable for occasions with large pressure difference.
