Enertech Cartridge Ball Valves are an innovative design that incorporates the positive features of ball, gate, and high performance valves resulting in a mechanically sealing, tight shut-off valve with a simple operation that provides outstanding performance. The valve design can be installed in a wide variety of nuclear power plant applications to provide safe and reliable operation.
The HCV and BCV do not rely on springs to create the sealing in the closed position. These valves seat by way of a positive mechanical load on the seat at the full closed position. This provides a tight seal at both low and high pressures regardless of differential pressure direction.
The HCV closing member (HEMI) cuts through the media stream similar to a gate valve, reducing turbulence/cavitation normally experienced in ball valve designs, while providing a more uniform/fluid flow of media flow. At full closure, a positive mechanical load is created between the HEMI and the seat. The HCV provides bubble-tight shutoff at both low and high pressures every time.
The BCV uses several of the same design features of mechanical sealing and is suited for standard block valve applications where the end user is in need of a reliable shut-off valve.
