The M&J Valve Model M-303 is an advanced design slab gate valve for high pressure differential applications in the oil & gas sector. It is designed to simplify installation and upgrades, improve safety and reduce environmental impacts.
How it works
The M-303 features a floating slab gate that uses the natural force of line pressure to obtain a reliable, dynamically tight downstream seal. Low pressure sealing is accomplished with coil springs that energize the seat, pushing it firmly against the gate.
