Product Description:

Gas ball valves can be used exclusively for gas and non-corrosive gas piping control such as natural gas, gas, liquefied gas, etc.  flow control. Suitable for long- distance pipeline for natural gas, artificial coalfired gas and liquefied gas, and urban gas transmission and distribution pipes Net, with floating ball two-piece typical structure, full-diameter design, stainless steel ball, simple structurer and safe operation Easy installation, labor-saving operation, easy maintenance, safe performance, reliable, high corrosion resistance, etc.

Working Principle:

Gas ball valve cartridge-piston guide device, i.e. between ball and valve stem, valve stem and valve body conductive spring is installed to form static passage between ball and valve stem and between valve stem and valve body to remove static electricity purpose. Avoid electrostatic ignition to ignite the medium and ensure the safety of the system. Tetra ethylene and result of a fire Ball valve can still be operated reliably and have good sealing properties to prevent fire when soft seals are burn out, etc. Expansion of disasters.

Product Characteristics:

1.      Gas ball valves is a special ball valve specially design for gas and liquefied gas pipeline, which is sealed during opening and closing. Small friction between surface, easy maintenance, long life.

2.      Colored PTFE (Polytetrafluoroethylene) and other material are use as seals, which have good lubricity and electricity and are compatible with balls. Small body friction system, long service life.

3.      Quick opening and closing, when opening and closing, only the hydrogen sphere needs to rotate 90 degrees, which convenient and fast.

4.      Ball valves have small fluid resistance and equal cross-sectional areas of ball passages, body passage and connecting pipe when fully open. And think straight, the medium flows through the ball valve, which is equivalent to flowing through a straight pipe, in all kinds of valves, the ball valve has minimum fluid resistance.

5.      Manual, worm wheel drive, pneumatic and electric (explosion proof) may be configured to realize remote automatic control. To meet the requirements of uses under various operating conditions, ball valves larger then DN150 are driven by worm wheels.
