The M&J Valves Model SG is a cast body design manufactured and tested to API-6D. The floating slab gate uses the natural force of line pressure to obtain a dynamically tight downstream seal in high- pressure differential applications. Low-pressure sealing is accomplished with an o-ring that energizes the seat and minimizes corrosion and debris build up. Common geothermal trims are available.
The M&J Valves Model S303G is an advanced fabricated body design manufactured and tested to API-6D. The fabricated body allows a wide selection of material choices. As with the Model SG, the S303G utilizes line pressure and o-rings to energize the seats and provide a tight downstream seal. Common geothermal trims are available.
