ESI supplied ‘V’ port control ball valve to the UK’s largest gas network supplier, who was installing a novel technology to balance the richness of nitrogen in the gas supplied to the grid.
The issue arose because the gas was imported as LNG, there was a requirement to have its richness adjusted and this required a valve that could deliver very low flow on start up, but yet ramp up to almost full flow under normal conditions. However, the valve was also required to offer very fine control and to adapt to nitrogen measurement levels during the process. This valve was the critical part of the entire system. ESI provided a Habonim control valve, which is designed to meet industrial demands for flow control systems – accurate, flexible, cost efficient and maintenance friendly. The valve is compact, lightweight with long life solution and performs well in the harshest environments. The wide rangeability, step-less characterized pressure and flow control as well as bubble-tight shutoff makes it desirable for critical applications. Other critical features include high pressure-drop capacity with straight-through flow, high CV and large exhaust capacity.
