Lee Products is introducing a new range of Chek Valves for use in purge air, water injection and liquid fuel applications, primarily for industrial gas turbines. One of the important benefits of the design of these valves is their ability to be quickly and simply disassembled to enable servicing to be carried out in the filed, using a rebuild kit.
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, featuring laser-drilled holes for optimum precision. The screen is capable of handling differential pressures up to 7500psid (518Bar) without collapse.
These power generation Chek valves, which can operate at temperatures up to 230degC, 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.
In addition, each valve is 100 per cent tested to ensure reliable, consistent long-term performance. These extremely compact Chek valves are available as a purge air and water injection option measuring just 144mm in length x 32mm in width, or as a liquid fuel option measuring just 86mm in length x 35mm diameter.
