Why Choose the M303?
Lower Emissions
Simplified Installation
Minimal Lifecycle Maintenance
Description
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

PRIMARY STEM SEALS
• Standard Graphite Spring Loaded Seal (SLS) Stem packing for longer service life.
SECONDARY STEM SEAL/PACKING INJECTOR
• Safety backup using plastic, non flammable stem sealant.
TOP ENTRY
• For efficient in line maintenance.
SPRING/PRESSURE LOADED SEAT RINGS
• With one wave spring, line pressure and nylon/elastomer seals provide a continuous positive seal in low or high pressure differential service.
FLOATING SLAB GATE
• Utilizes line pressure to obtain a dynamically tight seal by pushing the gate against the energized seat.
ADVANCED FABRICATED BODY CONSTRUCTION
• Fabricated body with minimum cavity volume.
• Optimized rib design and position enhances the pressure containment integrity of the valve body.
FULL THRU CONDUIT PORT
• For easy passage of pigs, wipers, and scrapers.
TRIM MATERIALS
• Choice of body and trim materials including regular, low temperature and sour crude services (NACE) designs.
