Zhejiang Hongqiu Valve Co., LTD was established in 1998, located in Wuxing Industrial Zone, Oubei town, Yongjia county, Wenzhou city, which is known as the "County of China Valves". The main producing center located in Yangliuhe Industrial Zone, Yunhe County, Lishui City, Zhejiang Province, China. HQV specialized in producing Ball Valves, Gate Valves, Check Valves, Globe Valves, and Butterfly Valves. From size 1/2'' to 48'', pressure rate from 150LB to 2500LB. Material such as A105, F51, SS304,SS316,WCB,WCC,CF8,CF8M,CF3, CF3M,etc.
Our products adopt domestic and international standard certificates in both design and manufacturer, such as ISO9001, CE, API 6D, ANSI, BS, DIN, GOST, TS,JIS, GB, etc..
Ball Valve has met the cracking requirement of anti-sulfur stress under teh sulfuration environment. Inner parts adopt nickel plated stainless steel and shrouding chooses polymer as sealing material that is applicable for a wide range of temperature and pressure. Material selection and test are in strict accordance with NACE (National Association of Corrosion Engineer USA). It has strong ability of corrosion-resistance and anti-sulfuration, stable sealign and good performance of fire resistance and electrostatic prevention, With complete specification, pressure, full bore and reducer diameter, this valve is an ideal one in flow system for chemical oil refining, oil gas exploitation and so on.
