Forged cryogenic trunnion ball valve manufacturers in India

Speciality Valves is one of the leading Forged cryogenic trunnion ball valve manufacturers in India with excellent rating, which provides highly durable and precision-critical valves capable of working under ultra-low temperatures. The valves are produced in high-grade forged material to provide strength, longevity, and best resistance in cryogenic applications using liquefied natural gas (LNG), liquid oxygen, nitrogen, and hydrogen.

Why Required?

Cryogenic service demands valves capable of withstanding thermal stress and leak-tight sealing under sub-zero temperatures. Forged cryogenic trunnion ball valves are crucial in ensuring efficient control of flow securely under such situations. The forged body provides extra strength, while the trunnion-mounted type provides extra control and stability.

Key Components of Forged Cryogenic Trunnion Ball Valve:

Forged Body: Provides enhanced strength and fatigue life

Trunnion-Mounted Ball: Provides symmetrical seal and low torque operation

Extended Bonnet: Prevents freezing of stem and packing

Seats & Seals: Cryogenic-resistant materials for bubble-tight sealing

Anti-Static Device: Ensures safety in explosive atmospheres

Working of Forged Cryogenic Trunnion Ball Valve:

The valve depends on the fixed (trunnion-supported) ball concept which turns to regulate flow. The pressure from upstream drives the seat rings against the ball and seals it leak-tight. The bonnet extension keeps the stem and gland area above freezing point, thus making it leak-tight for safe running in cryogenic service.
