C91
Product information
Habonim bi-directional cryogenic trunnion ball valves Series C91 with ISO 5211 top flange feature spring-loaded seat construction with piston effect (SPE and DPE) to prevent pressure buildup in the ball.
The minimal fluid layer between bonnet and spindle ensures a leak-free spindle seal. All Habonim cryogenic ball valves feature the patented Total HermetiX™ spindle seal (certified for 500,000 cycles ISO 15848-1) and come standard with double body seals for maximum integrity. The use of short housing bolts minimizes thermal expansion and prevents leakage at the housing seals.
