Zhejiang MingTai Valve Co., Ltd locates at Oubei Town, which is the Chinese hometown of Pump & Valves. Set up in 2000, we now have almost 300 employees.
We are a professional company which intergrades with scientific researching, manufacturing, and selling of fully welded ball valves and forged steel valves (gate / globe / check /ball valves).
The size of our fully welded ball valves vary from DN 15 TO DN 1400 (1/2 to 56”), body material can be pipe material ST37.8 and forged steel material A105 /LF2 /F304 /F316 .etc. With all welded structure, our ball valves make a great improvement of sealing quality both inside and outside, as well as lower weight, so they are especially applicable for district heating and natural gas ,city heating, city gas, petrochemical industry, shipbuilding, steel, offtake station, power plants and other pipeline equipments.
The size of our forged steel valves varies from DN15 to DN50 (1/2 to 2”), body material can be forged steel material A105 / LF2 / F5 / F11 / F22 / F304 / F304L / F316/ F316L .etc. The connection ends can be socket welding, butt welding, threaded and combines ends in ANSI Class 800, 1500, 2500. Available also for welded flanges or integral flanges in 150LB, 300LB, 600LB, 900LB, 1500LB and 2500LB either with raised face or ring type joint ends. The design standard can be API, ANSI, DIN, BS, JIS, JB, HG, and GB. Etc. Our forged steel valves are available in three bonnet designs, bolted bonnet, welded bonnet and pressure seal bonnet. We can also manufacture as per customers’ requirements. These high quality forged steel valves are widely used in oil, gas, chemical, petrochemical, power generation and marine industries.
We also provide other valves like cast steel gate valve / globe valve / check valve / strainer / butterfly valve. etc.
All our products are qualified with valid international certificates of CE ( PED97/23/EC Annex Ⅲ Module H ) / ISO9001 / P-MARK.
80% of our valves are exported to other countries , such as Russia , America , Germany , Sweden , Kazakhstan , Korean , Thailand , Brazil , Austria , Spain , Iran , Croatia and other countries .
We believe with our continuous research and innovation, we’d be trustworthy and our products would win the world markets for good quality, best service, competitive price and fast delivery. And we'd surely believe to achieve win-win cooperation with you on the basis of equality and mutual benefits.
