Jiangsu Lan valve General Equipment Co., Ltd research and development, production and sales of various types of valve actuators WSD Series two-way valve pressure gas main characteristics and uses: the use of seals valve degeneration compensation mechanism, so that the loss of part of the specific pressure compensated, not only to ensure that the valve hundred percent of the rated pressure capacity, and the valve in the reverse action of the first valve media network, to achieve the medium pressure bearing capacity of at least fifty percent, if the customer can achieve one hundred percent anti-bearing capacity, only one way to solve the ordinary pressure valve, easily reverse leakage defects. Especially for gas drainage system, the need for multiple pipeline interconnection pipeline flow switch or adjust the special conditions. Meanwhile, the special anti-corrosion treatment and sealing materials paired fully meet the high-explosive nature of coal mine gas, and coal dust particles under highly corrosive media, require long-term, safe operation requirements. Jiangsu Lan valve General Equipment Co., Ltd. has sophisticated machining equipment and testing equipment, has a sound and effective quality management system. The company sells its production to meet bi-pressure gas valve of high-explosive mine gas, and coal dust particles under highly corrosive media, require long-term, safe operation requirements. Supporting ZB / QB series of mine electric valve actuators, comes with 4 ~ 20mA valve position feedback signal unit wearable valves, stronger anti-interference signal output; and "KXBC series flameproof electric valve control box" supporting the use of can interface with the DCS series, fully automated production equipment to meet the coal needs. Proof valves, valve Oubei, 江苏兰 valve provided by 江苏兰 valve General Equipment Co.江苏兰 valve General Equipment Co., Ltd. (www.lanfa.cn) strong, credible, in Changzhou, Jiangsu regulating valve industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Jiangsu Lan valve and you hand into the brilliant, for a better future!
