Basic Concept
- Gate Valve: Also known as a sluice valve or shut-off valve. Its main function is to stop or allow the flow of fluid without affecting the flow rate or velocity.
- Steffenini Gate Valve: Manufactured by Steffenini – Italy, a well-known company specializing in industrial valves, particularly for the oil & gas, chemical, and water treatment sectors.
- Operating principle: The gate (disc) moves up and down perpendicular to the flow. When fully open, the flow passes through unobstructed; when closed, the gate presses tightly against the seat, ensuring high sealing performance.
