- 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.
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.
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.
