ZZWT self acting temperature control valve

Self acting temperature control valve is also named as directly acting control valve. It does not need extra outside energy and can make use of energy of adjusted medium itself to realize automatically control. It can regulated parameter including temperature, pressure, differential pressure, flow rate and so on. As to usage of Self-acting temperature control valves, once putting temperature bulb into pipelline, temperature changes accordingly, The scope of temperature setting is wide, which is easy to control. With protection of excess temperature, It is safe and reallzable. It is convenient to set temperature, even during working period setting can be executed.
