Design the characteristic:
DF series butterfly 's valve gives play to the superior function in preventiong forming revealing. Technology and unique multi-level more and more close contact -type valve flatthat experience develop that utilize for many years accumulating. Synthesize other multiple DF series butterfly valve of technology more and more field substitute other valves, have characteristic with simple construction and having long performance life
Outstanding lasting sealing property:
Unique multi-level advances gradually the contact TPE valve seat design, causes the valve board gradually to contact the valve seat in the closure process. During guarantee good sealing property, reduces the nonessential torque, thus lengthens the valve seat the service life.
1. The ultra light aluminum alloy valve body. The torque is small
2. The use installment is convenient, ceases the rust eclipse
3. The torque reduced realizes the drive weight to be light and the minaturization
4. Is in sole possession of the valve lever packing ring prevented the fluid divulges
5. The different material quality valve seat, the adaption different operating mode, has the good anticorrosion harmoniouly to seal the performance
The ball -and -socket valve board path causes the valve rotation to be fl-exible freely
The valve disc is formed according to a complete sphere processing, the packing surface each part all is a packing surface when seal, although has the contact, actually is quite smooth, therefore the moment of force reduced, the sealing property improved, specially the axial seal place friction reduced, used this technical the valve seat life to increase three times.
The vavle disc and the valve ring by the identical spherical surface processing, the valve disc friction steadily have not revolved.
Tianjin OTS Valve Manufacturing Co., Ltd. Established during the period of China's reform specializes in all kinds of industrial butterfly valves with 13340 square meters including 8600 square meters work-shop. Fixed assets of RMB20 million as well as some advanced processing equipments, among all 120 staffs (including 15 technicians). We can provide strong ability of design, processing, assembling and testing for all Butterfly Valves.
Further, we are rich in the experience of producing butterfly valves over 10 years, all of the butterfly valves we produced keep up to the advanced standard home and aboard. With perfect manufacturing innovation, we export all specifications of Butterfly Valve, Gate Valve, Check Valve and Filters, which size from DN40~DN2400, with different materials for Body, Disc, Stem, Pin, and Sealing. Working pressure 0.25MPa~2.5MPa.
To innovate more perfect products, we insist on the aim: High Quality, carrying on the ISO9001 Quality Standard and in line with EU Standard shown in CE certificate. All the staffs in the company are aware of the Importance of Quality and Safety, and any error occurring in design, producing and purchasing of materials, quality inspection must be controlled in our factory.
All our butterfly valves have got high quality reputation from all customers in the world. We have sold different types of valves to 29 provinces and regions in China, suitable to water works, electric power plant, metallurgy, petrifaction, irrigation and drainage, etc. And we also set-up long-time friendly business relationships with some customers from Asia, Europe and American.
On the basis of mutual benefits, friendly cooperation, fairly business, we offer perfect quality, sincerely service and reasonable prices to meet all the customers' requirement in the International market.
