Gate Valve serie
a type of valve that uses a flat or curved disc perpendicular to the process flow
The Gate Valve serie
Today’s O&G applications mean process control needs and safety system to limit any wild parameter and danger; the use of high reliable and well designed solutions to generate high efficiency and guarantee process efficacy is nowadays paramount.
Gate valves are a type of slide valve that uses a flat or curved disc perpendicular to the process flow; the disc slides into the flow stream to provide tight shut-off.
The fluid pressure acting on the disc is sufficient to produce a satisfactory seal between metal-to-metal seatings.
