Abstract

Pumping applications with high head, surge tanks, or multiple pumps, have long proved a challenge to system operators trying to minimize line surges resulting from slamming non-return valves. Traditional non-return valves use outside levers with weights or springs in an attempt to reduce slam. By doing so, they pull the disc down into the flow and reduce the length of the disc stroke so that it closes faster. Unfortunately, while outside levers and weights help solve one problem, they create two others. Increased pressure loss and maintenance are inevitable with traditional non-return valves. Pulling the disc down into the flow creates a blockage in the line and causes tremendous pressure loss and turbulence. The valve comprises bonnet, internal disc, drain pipe and inlet/exit duct for connection to upstream and downstream component and works at above or atmospheric pressure conditions depending upon process equipment configuration. In order to evaluate flow characteristics and pressure drop valves through measurement, investment for development test rig and associated instrumentation is required. Added to this, supply of working fluid at desired pressure to the valve is also needed to evaluate its performance. This is a slow process and requires the support of several agencies like skilled man power, space, procurement action of required instruments etc.
