Our Multi-Port Sealed Ball Valves (available in 3-way and 4-way configurations) are engineered for versatile flow control in complex piping systems. These valves allow for fluid diversion, mixing, and multi-directional flow management with a single valve body, reducing the need for multiple units and simplifying system design.
Designed for high reliability and bubble-tight shut-off, these valves are widely used in the chemical, petrochemical, food and beverage, and water treatment industries.
Key Features
Multi-Port Flexibility: Available in T-Port or L-Port configurations to meet various diversion and mixing requirements.
Four-Seat Sealing: Advanced four-seat design ensures a perfect seal in any flow direction, preventing bypass and internal leakage.
Durable Material Options: Available in heavy-duty Carbon Steel (WCB) for general use and Stainless Steel (CF8/CF8M) for corrosive environments.
Low Operating Torque: Precision-ground ball and high-quality PTFE/PPL seats provide smooth operation and extended service life.
Fire-Safe & Anti-Static Design: Built to meet industrial safety standards for hazardous media handling.
