4" PRESSURE SUSTAINING VALVES WITH SOLENOID CONTROL
Item No.: BIV100PS-
This valve is a hydraulically operated, diaphragm actuated control valve that sustains mini-mum preset upstream (back) pressure and opens fully when line pressure is in excess of setting.It either opens or shuts in response to an electric signal.
Description
PRESSURE SUSTAINING VALVES WITH SOLENOID CONTROL This valve is a hydraulically operated, diaphragm actuated control valve that sustains mini-mum preset upstream (back) pressure and opens fully when line pressure is in excess of setting.It either opens or shuts in response to an electric signal.
TYPICAL APPLICATIONS Computerize irrigation system; Line fill-up control solution;Line emptying prevention; remote and/or elevated plots; infield filters backwash pressure sustaining;energy saving irrigation systems; FEATURES 1.Line Pressure Driven, Electrically Controlled On/Off *Prioritizes pressure zones & controls system fill-up *Sustains upstream line pressure *Opens fully upon line pressure rise 2.Engineered Plastic Valve with Industrial Grade Design *Highly durable, chemical and cavitation resistant *No internal bolts and nuts 3.‘Y’ shape Valve Body with "Look Through" Design *Ultra-high flow capacity – Low pressure loss 4.Unitized Flexible Super Travel (FST) Diaphragm and Guided Plug *Accurate and stable regulation with smooth closing *Requires low actuation pressure *Prevents diaphragm erosion and distortion 5.Simple In-Line Inspection and Service
HOW IT WORKS The shuttle valve [1] connects the solenoid valve [2] or the pressure sustaining pilot valve [3] to the valve control chamber [4]. When the solenoid valve is closed, the pressure sustaining pilot valve causes the valve to be slowly closed when the upstream pressure [P1] is lower than the setting, and fully opens when [P1] rises above the setting. The solenoid valve is switched under the control of the electric signal, and the pipeline pressure is guided into the control chamber through the shuttle valve, and the pressure in the control chamber is increased to cause the valve to close. The solenoid valve also enables local manual shut-off of the valve.
