Overview
Key Features
• Low Flow Resistance & Energy Efficiency – When fully open, the flow path is straight through, resulting in minimal fluid resistance and reduced pressure loss, which saves energy.
• Bidirectional Sealing – The wedge‑type rigid single‑disc design provides reliable sealing in both flow directions.
• Tight Shut‑off – Ensures positive sealing when closed, effectively stopping fluid flow.
• Designed for Full Open/Full Close Service – Intended for fully open or fully closed positions; not suitable for throttling, as partial opening may cause vibration and accelerated wear.
• Corrosion‑Resistant Construction – Engineered for marine environments; materials and anti‑corrosion treatments withstand seawater, salt spray, and humid conditions.
• Online Maintainability – Some designs (top‑entry types) allow internal maintenance without removing the valve from the pipeline.
