<p>A valve system ( 200 ) for pressure exchanger tubes of an energy recovery system ( 100 ) is provided, The valve system includes a valve housing ( 304 ), a flow distributor ( 310 ), a hollow spool ( 302 ) and a sealing system, The valve housing may comprise a set of high-pressure ports ( 306 ) and a set of low-pressure ports ( 308 ). The flow distributor allows the flow to and from the set of high- pressure ports and the set of low-pressure ports within the valve housing, The hollow spool may be configured to reciprocate axially in a radial clearance between the valve housing and the flow distributor. The hollow spool may connect the pressure exchanger tube in fluid communication with the high-pressure ports or the low-pressure ports. The sealing system may be provided within the valve housing for imparting substantial hydraulic balance to the hollow spool.</p> |
