Gland Flange :A fully adjustable two-piece gland flange to make sure an even packing load over 360 °
Anti-Blow-Out Stem : Protecting stem blow-out caused by pressure.
Gland Bush : Standing alone with Gland Flange, preventing uneven down-pressure on gland packing.
Gland Packing : Use PTFE or same as Valve Seat. Performance is compliance with API 598’s
Valve Seat : Bi-direction zero leakage design. Use Higa-PTFE, RTFE, or UHMWPE
Taper Pin : Tangentially positioned half in disc and half in stem to
eliminate potential of failure.
Patented Retainer Ring : A no-screw-floating degin to elimate cold flow. This deign
provides positive tight shut-off of seat. Surface roughness is
Thrust Ring : Use 316 as material. Position in bottom of stem for preventing
incorrect stem shift.
Bottom Cover : Use rigid 316 as material to prevent abnormal leakage
Bottom Gasket : Use RTFE or GRAPHITE as material.
Valve Stem : Use stainless-steel with hard chrome plated. A strong and rigid
one-piece-stem design which largely increase overall strength.
Stem and corresponding components size are all compliance
with ISO 5211. Stem material and disc position is marked on the
top of stem.
Self-Lubrificant Bush : Use PTFE+316 as material to lower down stem’s friction factor.
Valve Disc : Use stainless-steel with hard chrome plated. A
streamlined design with great enhancement on
lowering noise and turbulence.
Valve Body :Compliance with API 609 & ASME B16.34. In order to make valve context
intuitive and straightforward, an additional name plate is designed to mark
Lock Pin and Spring :Use PTFE. While Reatiner Ring moves to locking position, spting will
pop-up and push pin locked in Reatiner Ring.
Thrust Plate : Use stainless-steel 316+PTFE to reduce operating friction between
Use RTFE or GRAPHITE as material. stem and bottom cover.
