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)
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.;
All welded ball valve material:
1): Valve body: carbon steel ST37.0, A106-B; No. 20 steel
2): Sphere: Stainless steel 304 or 316
3): Stem: 2Cr13
4): stem seal: perfluoro-like glue
5): Sphere seal: PTFE (PTFE + C)
Standard features of all welded ball valves:
1): Path: DN15～600
2): Pressure: PN 16～64
3): Working temperature: -29 ° C ~ +200 ° C
4): All welded ball valve adapts to medium: water, oil, natural gas
5): All-welded ball valve operation mode: water, oil, natural gas
Fully welded ball valve features:
1): Since the all-welded ball valve body is welded, the valve is light and easy to insulate.
2): The spring-loaded PTFE sphere seal ensures absolute tightness under all application conditions
3): All welded ball valve ball and stem are made of stainless steel with two o-ring anti-flying valve stem structure to ensure the tightness, the upper container can be replaced, the working life is long
4): All welded ball valves are available in welded, wired and flanged versions
5): Obtained ISO 9001 certification
6): Steel ball valves are suitable for use in local heating and cooling systems, pressure gas lines and oil lines.
