Flanged ball valve for gas

Product Description

Gas ball valve can be specially used for natural gas, coal gas, liquefied gas and other gas and non-corrosive gas pipeline control and

flow control. Applicable to long-distance pipelines of natural gas, artificial coal-to-gas, liquefied gas, and urban gas pipelines

The net adopts the typical structure of two-piece floating ball, full diameter design, stainless steel sphere, with simple structure, safety

It has the characteristics of convenient installation, labor-saving opening and closing operation, convenient maintenance, safe and reliable performance, and high corrosion resistance.

working principle

Gas ball valve spring-column plug type electrostatic lead-out device, that is, between the ball and the valve stem, the valve stem and the valve body.

Set the conductive spring to form an electrostatic channel between the ball and the valve tip and between the valve tip and the valve body, so as to eliminate static electricity.

Purpose. Avoid electrostatic ignition to ignite the medium to ensure system safety. teflon as a fire

When the soft sealing ring is burned out, the ball valve can still operate reliably and has good sealing performance to prevent fire.

the expansion of the disaster.


1. The gas ball valve is a special ball valve specially designed for gas and liquefied gas pipelines. It is sealed during the opening and closing process.

The friction between the surfaces is small, the maintenance is easy, and the service life is long.

2. The color uses PTFE (polytetrafluoroethylene) and other materials as the seal, which has good lubricity and elasticity, and is compatible with the ball.

The body friction system is small and the service life is long.

3. Quick opening and closing, only the hydrogen sphere needs to be rotated 90° when opening and closing, which is convenient and fast

4. The fluid resistance of the ball valve is small, and the cross-sectional area of ​​the ball channel, the valve body channel and the connecting pipe is equal when it is fully opened.

And figured it out in a straight line, the medium flows through the ball valve, which is equivalent to flowing through a straight pipe.
