Conducting surge analysis and supplying & fixing 150 mm dia of Electrically operated surge anticipating valve With Double Relief System. The work involves conducting detailed surge analysis of the water pumping main contemplated under this scope and to provide advanced and compact surge anticipating valve at appropriate location. The technical data available with authority m respect of the Raw water pumping main and scheme will be handed over to the contractor/firm in due course of time. All other details needed for providing appropriate surge anticipating valve have to be collected by the contract firm at his scope and risk. The work involves supply, erection and commissioning of suitable Electrically operated surge anticipating valve With Double Relief System with appropriate fittings and accessories such as DI Air valve, Tee, pipings, isolation valves (Gate valve made of DI), MS fabricated pipes etc complete for the satisfactory functioning of the devise. The surge anticipating valve should comply the following requirements. Automatic, solenoid control valves activated upon pressure in the pipe line. The valve to be fixed as per standards as identified on the basis of surge analysis work by the firm. The valve should open within less than a second after power fails with support of battery power. The opened valve should allow the release of the returning flow, thus preventing from developing surge in lines. The valve should close when a preset time is elapsed, adjusted by a time relay and needle valve, which disconnects the battery power. Closure time of the main possibility of any material trapped by them. The valve need to have simple possible structure, enabling fast and easy maintenance by unskilled local operators. The control system shall consist of 50mm hydraulic relief valve that drains the control chamber of the main valve within 0.5secs 12 VDC or appropriate solenoid valve. High pressure opening pilot that controls the main valve and this pilot will be diaphragm- activated, spring loaded. Needle valve will be used as closure speed regulators of the main valve and 12mm or appropriate ball valve, used to isolate the control circuit. Strainer filter for the activation water.
