Celeros Flow Technology brand M&J Valve has introduced an improved version of its Model M-303 slab gate valve. The advanced design M-303 offers a host of features that will help the customers in the oil & gas sector to simplify installation and upgrades, improve safety and minimize environmental impacts – reducing total cost of ownership (TCO). Manufactured and tested for API 6D, the improved M-303 is ideally suited for high-pressure differential applications. Its floating slab gate uses the natural force of line pressure to obtain a reliable, dynamically tight downstream seal. Low-pressure sealing is accomplished with a single wave spring that energizes the seat, pushing it firmly against the gate. This reduction in seal requirements, coupled with high packing reliability, dramatically reduces the likelihood of fugitive emissions.
The latest models have the same footprint as previous versions. Components are also forwards and backward compatible. The M-303 is also fully interchangeable with most other slab gate valves on the market.
Available in line sizes 6″ – 84″, class 150-2500, and with a choice of manual, electric, hydraulic, or cylinder actuators, there is an M-303 to suit most any high-pressure differential application. In addition to meeting API 6D / ISO15848-1 specifications, the valve is certified fire-safe to API6FA / ISO10497.
