High-Performance Cryogenic Side-Entry Ball Valves – Supplier & Stockist

Features & Benefits

As a leading Velan Valve Supplier, Distributor, and Stockist, we provide cryogenic side-entry ball valves engineered for extreme low-temperature and LNG applications. These valves feature an integral bonnet extension, ensuring cryogenic liquids boil into gas before reaching the stem packing—minimizing energy loss and preventing operational failure.

Our high-integrity cryogenic valves are designed to resist thermal deformation, guaranteeing tight shut-off performance in critical LNG, industrial gas, and cryogenic processing systems.

Superior Seat Design

✔ Soft or metal-seated with hard-faced ball & seats for extended durability
✔ Trapped fluid prevention in body cavity for safer operation
✔ Low fugitive emissions (ISO 15848 compliant)

Key Features

  • Secondary seals in pure graphite for enhanced leak prevention
  • Anti-static device & anti-blowout stem for safety
  • Lip seal configuration for superior sealing
  • Extended bonnet optimized for cryogenic service (-196°C / -320°F and below)

Operational Flexibility

  • Manual operation (wrench/gear with padlocking)
  • Actuated options: Pneumatic, Hydraulic, or Electric

Testing & Certifications – Fully Compliant & Reliable

✔ BS 6364, MESC 77/200, ISO 28921 (on request)
