Reduce TCO, improve safety with this slab gate valve
This company has introduced an improved version of its Model M-303 slab gate valve (photo). The advanced-design M-303 offers a number of features that will help users in the oil-and-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 suitable 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 valve is available in line sizes 6 to 84 in., class 150–2,500 pressure rating and with a choice of manual, electric, hydraulic or cylinder actuators. — Celeros Flow Technology, Charlotte, N.C.
