Keckley is the premier manufacturer of high-quality pipeline strainers, check valves and knife gate valves. Keckley has been an industry leader for nearly a century by providing customers with innovative and reliable solutions. In addition to manufacturing and supplying pipeline strainers, check valves and knife gate valves, we're also a premier manufacturer and supplier of fabricated pipeline strainers, float & lever valves, control valves, suction diffusers and triple duty valves. The Keckley Company is an ASME Certified Code Shop. ASME “U” Code Stamp available upon request.


Liquid & Gas Pipeline Check Valves

Keckley liquid and gas pipeline check valves are designed for liquid or gas applications where protection from flow reversal in a pipeline is required.

Keckley offers three different types of check valves: Wafer Body Double Disc, Wafer Center Guided Silent, and Globe Center Guided Silent. Each check valve has advantages and disadvantages over the other, but all three outperform and outlast conventional swing check valves when installed properly. Read more.


Knife Gate Valves Manufacturer

The Keckley Style KGV knife gate valve has a large port which provides a low pressure drop across the valve and is better suited to handle slurries, solids, and other fluid/solid mixtures than average plug valves, butterfly valves, or ball valves. Read more.

Float & Lever Valves

Keckley float and lever valves are designed to control the level of liquids through mechanical actuation. Float valves are actuated through the attached float ball, float rod, and lever assembly, and do not require any external power source. Keckley lever valves are actuated through the use of some external power source such as manual operation, float boxes/mechanisms, electric motors, or other actuators through external linkage to the lever of the valve.

Keckley has been providing float and lever valves since 1962 and remains one of the largest domestic suppliers of float and lever valves. Typical applications include: open or closed storage tanks, process tanks, basins, receivers, condensate tanks, cooling towers, standpipes, feed water heaters, reservoirs, and swimming pools.

Industrial & Commercial Flow Control Valves

Keckley offers a complete line of industrial and commercial flow control valves to suit a wide variety of applications: air, water, hydraulic, steam, or gas.

Keckley control valves include: internally piloted, pressure regulating, pressure reducing, diaphragm regulating in both single and double seated, back pressure valves, safety & relief valves, and drip pan elbows.

Since 1914, Keckley engineering and manufacturing has been working for industry and commercial building installations worldwide. Keckley products excel in their construction and performance. With the purchase of Klipfel Valves in 1962, there was a combing of engineering talents and features of both valve companies resulting today in this complete line. Read more.


Suction Diffuser & Triple Duty Valves

Keckley manufactures suction diffusers and triple duty valves (TDV) as pipeline and pump accessories. Suction diffusers and triple duty valves provide specialized and unique functions different from other Keckley products.

Suction Diffusers

Keckley Style PSD suction diffusers mount to the suction side of a pump in either a horizontal or vertical position. It is designed to remove any foreign matter that may be hazardous to the pump or other system components, while providing the proper flow conditions to the pump. Where space is limited, the Keckley Style PSD can be used as an elbow (in some cases a reducing elbow) with a built in strainer for easy maintenance and system performance.

Triple Duty Valves

Keckley Style TDV triple duty valves are primarily required on the discharge side of a centrifugal pump in a hydronic heating or cooling system. The Style TDV functions as a shut-off valve, spring loaded silent check valve, and balancing valve. Read more.
