Automatic Recirculation Valves protect centrifugal pumps from damage that may occur during low-flow operations.  Minimum flow protection is accomplished with an automatic, modulating bypass that assures smooth pump operation between the minimum and maximum flow point on the pump curve.

 

No external power source is required.  These valves are self-contained and simplify the system design and installation.  Sizes range from 1 inch to 24 inches, including ANSI Class 150 through 2500 lb.  Valve internals are stainless steel with housings in carbon steel, stainless steel, or special machinable alloys.

The Backpressure Regulator (BPR)  is a self-contained, medium driven, modulating automatic pressure control device designed to maintain sufficient pressure in the upstream piping to minimize/prevent cavitation and/or flashing in a piping system with varying flow rates. The fluid must be maintained above vapor pressure from zero flow to maximum flow allowed by the BPR at velocity not to exceed 20 feet/second.

 

The BPR is custom designed to meet each specific application to protect the control device upstream that is varying the flow and pressure to the BPR.

FOR CONSISTENT PRESSURE REDUCTION

 

Multiport Throttles are used to reduce the pressure and flow volume of liquid media.

DESIGNS


Multiport Throttles are used in nominal widths ranging from 1” to 20”, in pressure steps up to ANSI 2500 and up to a temperature of 700°F. The throttle housings are normally made of Carbon Steel (C22.8) steel suitable for pressurized vessels, but can also be made of various types of stainless steel, depending on the medium.
