Z43F Flat gate valve with diversion hole
The Flat Gate Valve with Diversion Hole is designed for oil, gas, and pipeline applications requiring pressure equalization and smooth operation. The diversion hole built into the gate balances pressure across the valve, reducing operating force and improving sealing reliability. Its full-port structure ensures unrestricted flow and dependable shut-off performance.
Flat gate valve with diversion hole
The Flat Gate Valve with Diversion Hole is a through-conduit gate valve specifically designed for high-pressure pipeline systems. The diversion hole incorporated into the gate allows pressure balancing between upstream and downstream sides when the valve is in operation, significantly reducing opening and closing torque.
The valve provides a full-bore flow path, minimizing pressure loss and allowing pipeline pigs to pass through easily. This makes it an ideal choice for long-distance oil and gas transmission pipelines, storage facilities, petrochemical plants, and industrial process systems.
As a professional industrial valve manufacturer, we provide comprehensive OEM and ODM services for global industrial projects.
Our Flat Gate Valves with Diversion Hole are manufactured according to international quality and performance standards.
