Since the vertical temperature control valve does not require any external energy sources, energy use was adjusted to achieve medium itself automatically adjust the actuator products. The biggest advantage, can no electricity, no gas in the workplace, while saving energy, the pressure setting can be adjusted during operation. The fast-opening flow characteristics, is sensitive, good sealing performance, which is widely used in petroleum, chemical, electric power, metallurgy, food, textile, machinery manufacturing and residential construction buildings and other industrial equipment using gas, liquid and steam medium vacuum, voltage regulator (for valve adjustment), or relief, regulator (before adjustment for the valves) and automatically controlled.
