Directly buried fully welded ball valve
Advantage:
Proof and standards;
Specially designed for pipeline applications of gasoline (liquefied natural gas/liquefied petroleum gas);
Can have the same lifespan as the pipeline system;
Lubricating oil, low operating cost;
Bidirectional valve;
Special coatings that can be used for corrosion prevention

Main features:
Connect one end to the valve body and the other end to the pipeline (note: the size standards for connecting ends are ASTM, EN, KS/JIS, etc.);
Mirror polishing requires inspection of the entire stainless steel sphere;
Bubble tight sealing and carbon reinforced PTFE (Teflon) valve seat;
Pre loaded seat cushion spring ensures tight low-temperature leakage and reduces valve operation torsion force;
Oppose bursting valve stem according to standards;
Two O-rings ensure the valve stem is sealed and replaceable;
The valve stem dry bearing and metal with PTEF coating have automatic lubrication capability, without the need for additional lubricants;
The valve stem and port connecting pipeline can be extended according to customer design requirements

Material:
1. Valve body: Carbon steel ST37, A106-B, STPG 370, A105, ASTM A516-60, A216-WCB or equivalent. Stainless steel 304 or 316 (choose according to requirements)
2. Sphere: Stainless steel 304 or 316 grade
3. Valve seat: PTFE, reinforced PTFE, Nylon, Peek, etc
