Ball valve application

Ball valves are usually made of rubber, nylon and Teflon as the seating ring material, so its temperature limited by seating ring material. Metal sphere the due role of the ball valve in the presence of the media, in between plastic seat pressing done (floating ball valve). Seating in a certain amount of contact pressure under the action of local elastic-plastic deformation occurs. This distortion can be compensated the sphere of manufacturing accuracy and surface roughness to ensure valve sealing performance.

Ball valve seat rings are usually made of plastic, so the choice of ball valve structure and performance, ball valve fireproof and fire should be considered, in particular in sectors such as petroleum, chemical industry, metallurgy, combustible and explosive media equipment and piping system using a ball valve, should pay more attention to fire resistance and fire protection.

Typically, in a dual-level regulation, sealed tight, mud, wear and tear, necking channel, opening and closing movements quickly (1/4 gate), high-pressure (pressure difference), low noise, gas point and vaporization phenomena, a small amount of leakage into the atmosphere, low operating torque, small resistance for fluid piping systems, recommended the use of ball valves.
