All welded ball valve USES:

1) : the city gas: gas output pipeline, trunk and feeder supply, etc.

2) : the central heating: large heating equipment output pipeline, trunk and feeder.

3) : heat exchangers, piping and the opening and closing of each circuit.

4) : steel mills: all kinds of fluid pipes, exhaust pipes, gas and heat supply pipeline, the fuel supply line.

5) : all kinds of industrial equipment, all kinds of pipes, all kinds of industrial gas and heat pipe heat treatment.

All welded ball valve material:

1) : body: carbon steel ST37.0, A106 - B; 20 # steel

2) : sphere: stainless steel 304 or 304

3) : stem: 2 cr13

4) : stem seal: perfluorinated like glue

(5) : ball seal: RTFE PTFE + C)

All welded ball valve performance:

1) : I don't need to maintain, adjust and lubrication, easy to install, low in operating cost under long-term reliable operation. Surface using pensu processing, gloss and beautiful, are brought in the country

The first level. There won't be the phenomenon such as external leakage. The body is welded structure, so the valve light weight and easy for insulation. Install regulator, very simple, the operation can handle

To be removed, reversing the installation.

2) : because the seat is made of carbon fibre reinforced teflon seal ring and disc spring, so the ability to adapt to the change of pressure and temperature, the pressure and temperature range

Any leakage of slide.

3) : the sphere have advanced computer processing detector tracking detection, so the sphere of high machining accuracy.

4) : as the body material as pipe material, won't appear uneven stress, also won't because of the earthquake and the vehicle through the ground deformation, occurs when pipe ageing resistance.

5) : integral whole welding, such as diameter and variable diameter channel, the fixed and floating ball, double piston effect sealing system, automatically

Injecting sealant bearing.

6) : in order to prevent electrostatic, stem and sphere and valve stem and packing box with a ball and spring respectively, between conductive can keep all parts of valve and valve body, let electricity pass through

District, the release of static electricity. Not only prevent fire, and to prevent corrosion, the realization of a temporary cut, in order to timely maintenance.

7) : stem resistance function is because a pressure in the valve stem, always so the force generated from stem designed to prevent to take off the structure.

8) : the thrust washer with low friction material support will be pressure to the valve stem, the stem just have the effect of torque.

All welded ball valve standard features:

1) : size: DN15-1000

2) : stress: PN 16 ~ 40

3) : working temperature: - 29 ℃ ~ + 200 ℃

4) : pipeline welding ball valve to adapt to the medium: oil/gas, liquefied natural gas (LNG)/liquefied petroleum gas, petrochemical, steel mills, heating pipes, etc

5) : pipeline welding ball valve operating mode: handles, gear (vertical/horizontal), electric, gas turbine
