Gate valve M-303

manualelectrichydraulic

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. M-303 highlights Reduction in seal requirements and high packing reliability for minimal fugitive emissions Two-piece stem, common yoke design and bolted packing retainer for simple operator mounting and conversions Transparent PVC stem cover for visual confirmation of valve status Seat lubrication ports as standard for easy assembly of lubrication kits Different materials for wetted areas for improved service life Single seat spring ring for quicker maintenance No packing intervention necessary, reducing downtime Same footprint as previous version, for easy upgrading Specification Available in line sizes 6" - 84", class 150-2500 Choice of manual, electric, hydraulic or cylinder actuators Manufactured and tested to API-6D Certified fire-safe to API6FA / ISO10497 Fully interchangeable with most other slab gate valves
