| Siphon Breakers | Dynamic Air Valve | Electronically Actuated Surge Anticipation Valve | Horizontal Cylinders |
| Uses the concept that a submerged discharge located at a lower elevation than the required discharge creates a siphon which lowers the total head required by a pump. A siphon breaker valve is placed at the top of the siphoning section of pipe. This valve is open when the pump is not operating or is beginning to close, breaking the siphon. It allows air to discharge during pump start-up. When the pipeline is full, the valve closes and maintains the siphon. (Surge Only) Learn more…. | After activation, Dynamic Air Valves continue to allow water (not just air) to flow out after all air is vented. The valve is gradually closed to reduce water column velocity in a highly controlled manner eliminating the air slam pressures. (Surge Only) Learn more…. | This is a combination of a Surge Anticipation Valve and an Hydraulically Actuated Surge Anticipation Valve. Opens at a specified pressure at a separate source. (Surge Only) | For Closed Surge Tanks & Bladder Tanks. When specified in the Surge Tank data, the horizontal tank is automatically handled as a variable area tank accounting for the volume/depth relationship for this tank alignment. (Surge Only) |
| Holding Tank | File/Table Pumps | Check Valve Element (independent of Active Valves and Pumps) | |
| Represents a tank with sump-type pump inside. Pump is controlled based on liquid level in the holding tank. Area of the tank, inflow into the tank and pump characteristic data is specified. (Surge & KYPipe) | Suter diagram pump for which multiple characteristic data points may be specified rather than specifying just a single operating point. (Surge & KYPipe) | The check valve closure characteristics may be based on the closure characteristics of standard valves (stem position vs. area ratio for Ball, Butterfly, Globe etc). Accelerated closure, differential pressure and flow may also be applied. | |
