Velan Valve Supplier | High-Performance Ring Valves for Demanding Applications

As a leading Velan Valve Distributor and Stockist, we provide patented Velan ring valves—engineered for intrinsic safety, reliability, and superior throttling performance in critical industries like coking and refining.

Key Features & Benefits

1. Intrinsically Safe Design

  • No seats required – Unlike conventional valves, Velan’s patented ring valve eliminates seat damage risks.

  • Throttling valve – Designed to avoid full closure, preventing drum overpressurization without mechanical stops.

2. Steam Purge System

  • Steam purges to bellows and body areas prevent coke buildup, ensuring uninterrupted operation in harsh environments.

3. Superior Throttling Performance

  • “Maximum obstruction” position delivers a pressure drop equivalent to a 15° open butterfly valve, optimizing flow control.

4. Robust Automation Options

  • Electric, hydraulic, or pneumatic actuators tailored for coker service with high torque safety factors.

  • Built to cycle reliably under extreme conditions, with durability for coker deck environments.
