China High Quality Stainless Ball Valve Suppliers – Flange Fully Welded Ball Valve – UNIQUE
China High Quality Stainless Ball Valve Suppliers – Flange Fully Welded Ball Valve – UNIQUE Detail:
Standard features of flange fully welded ball valves
1) diameter: DN15 ~1000.
2) pressure: PN 16 ~ 40.
3) working temperature: – 29 ℃ ~ + 200 ℃
4) gas pipeline welding ball valve adaption medium: petroleum/gasoline, liquefied natural gas/liquefied petroleum gas, petrochemical, steel plant, heating pipeline, etc.
5) gas pipeline welding ball valve operation mode: handle, gear (vertical/horizontal), electric, turbine.
Flange fully welded ball valve material
1) valve body: carbon steel ST37.0, a106-b;20 # steel
2) sphere: stainless steel 304 or 316.
3) stem: 2Cr13.
4) valve stem seal: all fluorine like glue.
5) ball seal: RTFE (PTFE+C)
Flange full welding ball valve performance
1) : no maintenance, adjustment and lubrication, easy to install and reliable operation under low operating expenses.The surface adopts the spray – plastic treatment technology, the luster is beautiful, in the country already at the leading level.There will be no external leakage.The valve body is welded, so the valve is light and easy to insulate.Installation adjustment mechanism, very simple, the handle can be removed, reversing 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 annotation of pressure and temperature range will not produce any drainage and smooth.
3) : the machining process of the ball has advanced computer detector to track and detect, so the machining accuracy of the ball is high.
4) : as the body material is the same as the pipe material, there will be no uneven stress and no deformation due to the earthquake and the vehicle passing through the ground. The pipeline is resistant to aging.
5) : integral whole welding, equal diameter and variable diameter channel, with fixed ball and floating ball, double piston effect sealing system, automatic injection of sealant type 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 are area, release of static electricity.Not only prevent fire, but also prevent corrosion, realize temporary cut off, in order to timely repair.
7) : the stem function of the stem is because the valve stem is affected by the pressure inside the valve, and it always produces a disconnection force, so the stem is designed to prevent the structure.
8) : press the thrust washer with low friction material to push the pressure to the stem, so that the stem only ACTS as a transmission torque.
