dimension to ASTM / EN / KS / JIS / GOST Standard .etc will be
available.
Bubble tight excellent sealing with PTFE+C seats.
Pre-loaded seat springs ensure leak-tight at low pressure and
reduce valve operational torque.
Anti blow-out stem.
Double O-rings ensure the stem sealing and are replaceable.
Stem dry bearing, metal with PTFE coating having self-lubricating
capabilities. (Additional lubricant unnecessary.
