Internal thread ball valve and welded connection valve, there are three types: monolithic, two-stage and three-stage. Valve casting introduce advanced technology from Taiwan, reasonable structure、beautiful shape. Valve seat using elasticity sealing structure, reliable sealing , open and close conveniently. Valve stem using bottom-mounted structure with down sealing, pressure of valve chamber increase abnormally, valve stem will not be taken out. Connection of two-stage and three-stage ball valve: butt welding(BW) socket welding(SW), also with international ISO stent platform and locking device. Can be set 90° position structure. Drive mode: manual、electric、pneumatic

Uses :

Internal thread ball valve and butt welded ball valve used in nominal pressure PN1.0～4.0MPa, working temperature -29～180℃(sealing ring is PTFE) or -29～300℃(sealing ring is counterpoint polystyrene) pipes, for cutting off or connect media of pipes

Using different materials, respectively suitable in water、steam、oil、nitric acid, acetic acid and other media
