Control Valve Applications. • Pressure Reducing. • Pressure Relief/Sustaining. • Pump Control. • Rate-of-Flow Control. • Level Control. • Cavitation Control . station. • Electronic pressure reducing valves provide a wider range of pressure control as compared to actuated ball valves. • Electronic control valves were equipped
1 Oct 1997 6.2.1 Pressure Tank as Surge Chamber. 6-6. 6.2.2 Minimize Frequency of Pump Cycle. 6-7. Flow Control Valve. 6-9. Flow Controlled Pressure Switch. 6-9. Pump Cycle Where pressure exceeds 80 psi, it should be reduced before flow is turned into the valve. reducing station in the pipeline. This allows
Pressure Reducing, Back Pressure Sustaining and Flow Control stations are configured to facilitate pressure and flow control in a portion of a distribution system; such stations are used to create individual pressure zones while allow- ing movement of water between zones under special demand circumstances. Multiple func
A pump station is composed of four sets of components: • The building. • The hydraulic system: the pump and related piping. • The electrical system: the motor and its related components. • The control system: pressure, flow, and level switches. Pump Station Buildings. Introduction. In medium-to-large facilities, pumping
Unlike check valves, the pump control valve's speed of operation is not affected by line flow or pressure conditions. Stable operating times are essential in as a lift station application, the control valve can be supplied with a motor actuator. The operating times are adjustable in the field with special actuator motor controls.
? A minimum pressure of 30 psi in the water distribution system. ? A minimum pressure of 20 psi during fire flow conditions. ? Adequate water levels in storage tanks and pressure vessels. ? Adequate free chlorine levels in systems that require chlorination. ? Adequate protection of pumps and electrical equipment

of check, air, and control valves and their inherent flow and surge characteristics. Successful pressure. The causes and effects of these surges in pumping systems will be discussed along with equipment designed to prevent and dissipate surges. Only with . Every pump station designer has been faced with check valve.
To achieve a required flow through a pumping system, we need to calculate what the operating pressure of the system will be to select a suitable pump. .. speed we can control the flow to the receiving tank to 2500 m 3 /hr over the entire head range. PUMP SELECTION. By repeating the calculation for D. H for a range of.
pumping station is offered. Specific attention is paid to the consumed power estimates in solo and multi-pump stations. After that, a PLC pump control system is described.. II. MATHEMATICAL MODEL OF PUMPING PROCESS. Among the variables described the pumping process the most important are the flow rate Q, head
