AND NINETY TWO SQUARE METERS), has 112 staff( ONE HUNDRED AND TWELVE PEOPLE) , with focus on
manufacturing industrial valves, including cast and forged steel ball valves,fully welded body ball valve, split ball valve,
pipe welded body ball valve, steel plate welded body ball valve, PE ended ball valve, top entry ball valve, orbit valve,
pig valve, gate valves, globe valves, check valves, and butterfly valves. Valve sizing 1/2” to 56”, rating ANSI 150
through ANSI 2500, industries served covering oil & gas, refining & petrochemical, power & paper, LNG and
Cryogenies. After development of 6 years, today the company supplies products to more than 15 countries and regions in
the world and becomes one of the leading suppliers of industrial valves in China.
ZIGAO VALVE launched its quality management and safety system as ISO 9001, ISO14001, OHSAS18001 and
awarded API 6D, API 607, API 6FA, CE/PED approvals for the products.
ZIGAO established a multi-functional phys-chemical lab to further supervise the quality time to time, and fit out
spectrum analyzer, portable spectrograph (PMI), mass spectrometer, induction furnace infrared carbon, sulfur analysis
gauge, material tester, impact tester, spring tester, hardness meter, thickness meter, magnetic particle tester and NDE
testing equipment, and also other testing facilities for valve torque, service life, flowing capability, low temperature
application, low leakage and pressure test.
On innovation side, besides 2 patented valve designs, Which is the pipe welded ball valve (patent No.:
ZL200520113462.0) and the steel plate welded ball valve (Patent No.: ZL200520119076.2) there are around 10 new
products that developed by ZIGAO dedicated research team by 15 professional engineers in each year.
Upon the continues increase on customers demand, ZIGAO invested a more effective control line with machining center,
CNC lathe, CNC miller, CNC driller, plasma spray welder, auto painting & drying machine and ultrasonic cleaner.
ZIGAO is dedicated to supplying high quality valve solutions for global industries since its inception in 2008. In the new
century, ZIGAO is facing a historical development opportunity and furious competition. By holding the persistence
improving in management and product quality, ZIGAO will provide higher and better service to you.
