Automatic Recirculation Valve

Automatic Recirculation Valve (ARV) is a multifunctional valve that primary purpose is to ensure a pre-determined minimum flow is assured through a centrifugal pump at all times. This in turn has created a need for centrifugal pumps with high heads and low specific speeds.

Description

Flow Sensing Capability
Low pressure loss
Operational safety, reliability, and low maintenance.
Non-return Valve: Prevent reverse flow through the centrifugal pumps via the main line and bypass line.
By-Pass Control Valve: Protecting the pump from overheating by regulating the passage of fluid through the pump during start up, shut down and when the pump is run against a closed outlet.
Pressure Reduction Nozzles: Dissipate the pressure energy and allows the line fluid to be delivered to the by-pass system efficiently, safely and quietly.
Angle patterns valve has the additional feature of not requiring removal from the pipeline during maintenance ‘Shutdowns.’
Manual bypass operations are available
