The application graph illustrates the range of use forthree valve configurations: 1) base valve, 2) bottommounted oil dashpot, and 3) top mounted oil dashpot.For example, on a 2,500 ft. (762m) long watertransmission main operating at 150 ft. (4.5 Bar) of head,a Tilted Disc® Check Valve with a top mounted oil dashpotwould be selected. If a surge relief system is provided,then the bottom mounted oil dashpot configuration maybe used.

Applications
Energy Cost SavingsThe Tilted Disc® possesses the lowest headloss of any check valve available today, allowing the least amount of energyduring system operation to be consumed. The continuous electrical energy savings that result from using the Val-MaticTilted Disc® can be seen in the table below for 30 in. valves. This information was calculated using Val-Matic’s EnergyCost Calculator.
Top Mounted Oil Dashpot
Versatility ofOperation
Top Mounted Oil Dashpots aredirectly connected to the discand provide full open and closecontrol of the valve disc to fur-ther reduce the potential forsurges and water hammer.
Bottom Mounted Oil Dashpot
Bottom Mounted Oil Dashpotscontrol final stage of closing toreduce slamming associatedwith systems having rapid flowreversal characteristics.
