Leslie Controls, worldwide manufacturer of valves for the power generation, industrial, marine and oil and gas markets, features K-Max eccentric plug rotary control valve.
K-Max incorporates cam-action, low-friction plug operation that provides tight shutoff over a long service life in a variety of flow control applications, including high and low-pressure steam systems; clean, dirty, and corrosive liquids and gasses; and erosive and abrasive slurries.
Featuring bi-directional flow capability, the K-Max can handle mediums that are normally flowed to open and flowed to close. This design offers the advantage of using one valve style for many applications, allowing for plant standardization and minimal stocking requirements
The K-Max’s eccentric rotary plug action allows the plug to break free of the seat ring upon initial rotation of the shaft, resulting in a longer seat ring service life and improved shutoff integrity. The valve features a rangeability of 100:1, and has a self-aligning orbital seat. The seat ring and plug rigidly mate with every closure of the valve.
