Benefits
1International Certificates & Standards ;
2.Designed for district heating system , heat transfer piping , oil pipelines and gas industry application ;
3.Same lifetime as the pipeline system ;
4.Maintenance-free , no adjustment or lubrication with no running costs ;
5.Bi-Directional valve.
Main Characteristics
1.One-piece welded body & End piece connection pipe (Connection dimension to ASTM / EN / KS / JIS / GOST Standard .etc will be available.
2.Bubble tight excellent sealing with PTFE+C seats.
3.Preloaded seat springs ensure leak-tight at low pressure and reduce valve operational torque.
4.Anti blow-out stem.
5.Double O-rings ensure the stem sealing and are replaceable.
6.Stem dry bearing, metal with PTFE coating having self-lubricating capabilities. (Additional lubricant unnecessary.
