Products Details

Pneumatic three-way flanged ball valve is a three-way rotary ball valve used for medium diverting, merging and flow direction switching. The following is a detailed description of the pneumatic three-way flange ball valve:

Technical parameters:

Nominal diameter: DN15-DN300mm.
Nominal pressure: PN1.6-6.4MPa, PN16-4.0MPa
Connection type: flange connection.
Operating temperature: -30℃ ~ 450℃, -40℃ ~ 425℃.
Body material: WCB, 304, 316, 316L, ZG1Cr18Ni9Ti, ZG0Cr18Ni12Mo2Ti.
Applicable media: water, liquid, gas, oil, powder, steam, acid and alkali corrosive media, water, steam, oil, nitric acid, acetic acid.
Product features:

Low fluid resistance: its resistance coefficient is equal to the same length of the pipe segment.
Simple structure, small size, light weight.
Reliable sealing: ball valve sealing surface material is widely used in plastic, good sealing, has been widely used in vacuum systems.
Easy to operate: Just rotate 90° from full on to full off, easy to remote control.
Easy maintenance: Ball valve structure is simple, the sealing ring is generally movable, disassembly and replacement is more convenient.
Fully open or fully closed: the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause erosion of the sealing surface of the ball valve when passing.
