HWE Automatic Control Valve
HWE automatic control valves are specifically designed to meet the requirements of water utility systems, greatly improving supply and distribution system efficiency. Our valves have been tested and shown to be in compliance with industry lead content requirements.
HWE electronic control valves combine the efficiency of hydraulic control with advanced technology electronics to provide the optimum SCADA remote control solution.
Our retrofittable electronic accessories further enhance the functionality of your Automatic Control Valves, providing you with unparalleled control and superior performance.
Typical Application
|
Pressure Reducing Valve:
|
Pressure Reducing/Pressure Regulating Valve (PRV) automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. |
|
Pressure Relief Valve
|
Pressure Relief Valve is designed to maintain constant upstream pressure within close limits. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. |
|
Surge Anticipating Valve
|
Surge Anticipator Valve is indispensable for protecting pumps, pumping equipment and all applicable pipelines from dangerous pressure surges caused by rapid changes of flow velocity within a pipeline.
When using this valve, pumping systems are started and stopped gradually preventing harmful surges from occurring.

Electronic Control Valve
|
Surge Anticipator Valve is indispensable for protecting pumps, pumping equipment and all applicable pipelines from dangerous pressure surges caused by rapid changes of flow velocity within a pipeline.
When using this valve, pumping systems are started and stopped gradually preventing harmful surges Electronic Control Valves are designed for applications where remote control of the valve is preferred, making it the best choice for isolated locations; underground vaults, tanks and reservoirs; and pump control installations. Our Electronic Control Valves can be configured to perform a wide range of functions such as pressure reducing, pressure sustaining, flow control or level control. The valves can be easily interfaced with SCADA systems to add visibility of system performance.

|
Flow Control Valve
|
Flow Control/Rate of Flow Control Valves prevent excessive flow by limiting flow to a preselected minimum rate, regardless of changing line pressure. The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve. Accurate control is achieved as very small changes in the controlling differential pressure produce immediate corrective action of the main valve. |
|
Pressure Management Valve
|
Pressure Management Valves are the ideal solution to effectively manage water distribution pipeline pressure. These pressure control valves do this with an innovative two-stage hydraulic pilot system that allows for two downstream set points: a high pressure set point for high flow demand and a low pressure set point for low flow demand. In times of high demand, the Pressure Management Valve automatically adjusts pressure through the valve to meet the current conditions. When demand increases, the pilot senses the change and adjusts to the high pressure setting. This “pressure on demand” capability keeps the system from being over-pressurized while ensuring adequate fire flow. |
