Product Detail

The Didtek Lip Seal Trunnion Ball Valve is engineered for high-integrity sealing in the most demanding industrial services. Featuring advanced Spring-Energized Lip Seals, this valve provides superior performance compared to standard O-rings, especially in cryogenic, high-pressure, or aggressive chemical media. With integrated Vent and Drain ports, the valve facilitates full Double Block and Bleed (DBB) functionality, allowing operators to safely relieve body cavity pressure and verify seat integrity without interrupting the process flow.

Application & Function

Lip Seal with Vent & Drain Flange Trunnion Ball Valve are widely utilized in demanding environments due to their superior material properties:

LNG (Liquefied Natural Gas): Leveraging the flexibility of lip seals in cryogenic temperatures for reliable sealing in LNG storage and transport.
Oil & Gas Transmission: Enabling pigging operations, periodic drainage, and on-line seat integrity monitoring.
Chemical & Petrochemical: Handling highly corrosive, volatile, or polymerizing hazardous fluids.
Air Separation Units (ASU): High-pressure cryogenic circulation systems for liquid oxygen, nitrogen, and argon.
