Features

Offset valve stem and eccentric butterfly plate design-seat and disc do not contact during opening or mid-position, reducing friction and operating torque
Double safety anti-blow-out valve stem structure-independent stem retention mechanisms at both upper and lower ends, compliant with API 609
Two-way sealing flexible lip seat-elastic structure auto-adjusts with temperature and pressure changes; achieves bubble-tight (no-bubble leakage) two-way sealing
Internal travel limiter-reduces probability of seat damage and extends seat service life
Fireproof and anti-static structure (optional)
High-strength one-piece integral valve stem-ensures effective torque transmission and sealing integrity
Standardised valve stem head-allows actuator replacement without modification

Notes

Fireproof and anti-static structure is optional

Description

A triple-offset (eccentric butterfly plate and offset valve stem) high-performance butterfly valve designed for cryogenic service. The seat and disc do not contact each other during opening and mid-position, reducing seat friction and operating torque whilst improving seat durability. Suitable for use as a regulating and isolation valve handling cryogenic liquids including liquid oxygen and liquefied natural gas.
