SPX Flow M&J model M-303 slab gate valve

SPX Flow offers a range of flow control solutions that are suited to liquid terminals and tank storage applications. For precise fluid control, SPX Flow is offering the M&J model M-303 slab gate valve, which is 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 coil springs that energise the seat, pushing it against the gate.

The two-piece stem/common yoke simplifies operator mounting and conversions. The two-piece stem design also allows different materials to be used in wetted areas while standard material is used for stem threads.

Combined with the bolted packing retainer, the two-piece stem allows quick operator and extension changes in the field with the valve under pressure. For valves with ribs, a rib system has been developed to make painting and coating easy.
