fully welded body ball valves,seal welded ball valve

Fully welded ball valve of RF flange with locking device 1/4"-24"

Fully welded ftanged floating ball valves from series 1/4"-24" utilize flange connecting method to make them compatible with other flange-connected products. The valve replacement process is rather convenient These Kinds of valves are suitable for pipeline branches, underground pipeline, gas delivery equipment, liquid storage device, tunnel construction, etc.

Valve opening:flat steel handle (standard confìguration)/worm wheel (optional confìguration); motor driven/pneumatically driven/hydro driven (optionalconfìguration) 

Medium:water,oil,gas

Mainly include: all-welded ball valve, welded ball valve at flange end, fully welded ball valve with buried extension rod. Materials are WCB (A105), 304, 304L, 316, 316L, etc.;

Fully welded ball valve features:
