Lee Products has introduced a new range of Chek® Valves for use in purge air, water injection and liquid fuel applications, specifically for industrial gas turbines. The valves are available with or without, a removable, washable Hi-Bar® safety screen and this popular, with-screen version incorporates a one-piece component, which is machined from a solid piece of bar and features laser drilled holes for optimum precision. The screen is capable of handling differential pressures up to 7500psid without collapse. These power generation chek valves, which can operate at temperatures up to 230C, can also be designed according to specific customer requirements and so provide users with optimum application flexibility. They feature a stainless steel poppet design that, in combination with a Vespel® seat, allows for both low leakage and high flow. The Chek Valves are available as a purge air and water injection option measuring 144mm in length x 32mm in width, or as a liquid fuel option which measures 86mm in length x 35mm diameter.
