2. Stem, the pressure of the gas valve withdraw from liquid or is temperature values, etc. , according to the numerical debug the valve open/close of the effectiveness of a stem switch. 3. Heating the entrance to the personal understanding of the by-pass pipe as the archway resting heating, check repair or open when pipeline preheat, guarantee for the return water cycle, can ensure reliable network system. Widely used in water, steam, liquefied gas, machinery, power station, smelting metal, steel, pipe, construction, oil field, urban construction system, and other fields. 。 Stem valve is mainly divided into: temperature stem valve, steam ratio stem valves, cylinder type stem valves, semi-automatic stem valves, water mark a magnetic control valve, etc. Main function is to replace people mouth of pipes or vessels to stem, and the growth rate, at the same time to ensure the safety of the positions of the people. Q: the regulator the category of which some are there? A: the regulator temperature control valve, pressure regulator, the 3-way regulating valve, pneumatic diaphragm valve lining fluorine, air volume control valve, etc. Use: widely used in petroleum industry, chemical industry, pharmaceutical industry, water disposal, etc. Sectional type of valve, check valve has a Angle once-through globle valve by valve, plunger type; Commonly used by a gb cut Marine valve check valve, the valve, by the end of valve, jis standard by the end of valve, striped tube by the valve, the valve at low temperature, oxygen gas by the end of valve, stainless steel by the end of Industrial Valves, vacuum by the end of valve, etc. Widely used in chemical industry, fuel, power, metal smelting, textile, paper making, light industry, food, laboratory, etc. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
