The advantages of the pneumatic valve used in gas welding ball

the fuel gas in welding pneumatic ball valve of pneumatic valve adopts the structure of the whole welding, so won't appear the phenomenon of leakage, pneumatic valve is of compact structure, convenient for construction. Use self-lubricating sleeve, can in the case of low torque operation. It in closed position, both sides will be under pressure at the same time, some gas or liquid can be released from the discharge pneumatic valve. Pneumatic valve seat, with the design of the double sealed if upstream of the pneumatic valve seat is broken, downstream of the pneumatic valve seat can seal. And emergency sealing system, when the soft sealing surface damage, a small leak, auxiliary seal system by a temporary auxiliary seal. When the medium containing trace amounts of solid particles, through the injection system of injection cleaner or lubricant, do some necessary cleaning or lubrication. Under the greasing of the pneumatic valve is a one-way pneumatic valve, to ensure the media does not leak from this place.
