Keckley Company

Benefits & Features

Keckley wafer body double disc check valves offer an inexpensive way to properly protect your pipeline against flow reversal. Keckley cast iron wafer body double disc check valves have pin retainer holes in the body where plugs are inserted to hold the hinge pin and stop pin in place. Keckley offers a retainerless wafer body design in bronze, carbon steel, stainless steel, and other specially cast alloys.

Benefits & Features

Keckley retainerless wafer lug body double disc check valves offer an inexpensive way to properly protect your pipeline against flow reversal.

The Keckley retainerless wafer lug body double disc check valve features a single cast body without pin retainer holes in the body. This design minimizes prospective leak paths through the valve body making it a preferable option for highly toxic, corrosive, or hazardous gas chemical processing applications. Keckley wafer lug body double disc check valves are also suitable for liquid, natural gas, steam service, and vacuum service applications.

Keckley retainerless wafer double flange body double disc check valves offer an inexpensive way to properly protect your pipeline against flow reversal.

The Keckley retainerless wafer double flange body double disc check valve features a single cast body without pin retainer holes in the body. This design minimizes prospective leak paths through the valve body making it a preferable option for highly toxic, corrosive, or hazardous gas chemical processing applications. Keckley wafer double flange body double disc check valves are also suitable for liquid, natural gas, steam service, and even vacuum service applications.

Benefits & Features

Keckley wafer center guided silent check valves are designed to properly protect your pipeline against liquid flow reversal.

Keckley wafer center guided silent check valves are suited for liquid applications only. For applications requiring natural gas, steam, or vacuum service please refer to Keckley's wafer double disc check valve.

Wafer silent check valves are relatively short in design and provide a low cracking pressure. The spring automatically closes the disc at zero flow, which prevents flow reversal and water hammer. he disc is fully guided at the top and bottom to prevent binding and cocking.

Benefits & Features

Keckley globe center guided silent check valves are designed to properly protect your pipeline against liquid flow reversal.

Keckley globe center guided silent check valves are suited for liquid applications only. For applications requiring natural gas, steam, or vacuum service please refer to Keckley's wafer double disc check valve.

Globe style check valves are constructed from rugged castings that are machined to exacting specifications. The bodies have drilled flanges that are in accordance with ASME. The spring automatically closes the disc at zero flow, which prevents flow reversal and water hammer. The disc is fully guided at the top and bottom to prevent binding and cocking.

Benefits & Features

Keckley Style SP (Short Pattern) and Style LP (Long Pattern) reduced port wafer check valves are designed for limited space applications where a full-bodied check valve w ill not fit.

The Style SP and Style LP are designed for low flow applications. If needed, the Style LP can be machined to meet a specific face-to-face requirement.
