What’s Inside Matters
Engineered for Performance
Its robust design supports high pressure and temperature service, while full-port construction minimises flow resistance. With anti-blowout stem design and fire-safe capabilities, it’s ideal for demanding industries such as petrochemical, chemical, and refining.

01. Blow-Out Prevention
Integral stem shoulder design prevents blow-out and leakage, ensuring safe and reliable performance.
02. Anti-Static Protection (Dual Anti-Static Device)
Dual anti-static system minimises the risk of safety hazards caused by static electricity.
03. Reliable Stem Sealing
V-ring packing with a primary pyramidal stem seal delivers long-lasting and effective sealing.
04. Misoperation Prevention
Built-in limit device prevents accidental or incorrect valve operation.
05. Adjustable Hidden Gland
Stem packing can be tightened to stop leakage without removing the actuator, reducing downtime.
203 Series
The 203 Series Ball Valve is a high-performance, flanged-end valve engineered for process-critical applications requiring secure connections and consistent sealing.
