valve

Ball valve in the pipeline is mainly used for cutting, distribution, and change the flow direction of medium, It’s more used for the optimum switch, cut-off valve. It has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as in People's Daily life.

Welded ball valve features:

1 The valve weight is light and easy to keep warm.

2 The ball and stem material is stainless steel

3 The valve stem leakage structure has two "O" type sealing ring, The upside sealing ring can be replacement online.

4 With the spring load of PTFE valve ball seal ensures that the rigor of application scope.

5 There are welding, thread and flange multiple connection methods for selection.

6 Follow EN488 standards for testing.

7 Passed the ISO 9001 certification.

Applicable specifications:

1 scope: standard size, general size.

2 size: 15mm≤DN≤1400mm

3 pressure: 1.6 Mpa≤PN≤4.0 Mpa

All welded ball valve technology to solve the bottleneck:

1 It can be directly buried underground without building tall valve well and welded with the pipe, save screw, flange, gaskets, reduce the project cost.

2 When ball valve is opened, the valve ball seat completely surrounded with the ball, Although there is impurities, it can not scour seat and medium sphere seal face. Because of this special structure to make valve closure and has a long life with pipeline, So it can be used normally for 20 years.

3 When ball valve is closed, The static medium can not cause damage to spheres and the sealing sea;When open the ball valve, sphere can scrape the deposited stationary medium. There are spring under the seat made up for the changing of pressure and temperature. It ensure that won't produce any flaws.

4 It can prefabricated heat preservation, reduce a lot of heat loss.
