The flow test loop is the centrepiece of the company’s unwavering commitment to quality control and customer satisfaction. It is one of the most advanced valve test facilities in the world with a number of impressive statistics. The water storage tank has a capacity of 80 m³ and a total of seven pumps with an individual capacity ranging from 120 up to 2200 m³/h. The pumps are all electric motor driven with power ratings ranging from 30 to 500 kW. Different combinations of pumps can be used together, and the maximum flow capacity of the test loop is 4000 m³/h. The flow test facility has five separate stations for testing valves with nominal sizes from DN 25 up to DN 750 and two independent flow tests can be carried out simultaneously.
This test facility has a state-of-the-art PLC system that allows the flow test to be run fully automated, semi automated or manually. All of the critical performance parameters of the AR valve are measured and recorded. These include:
* Bypass flow capacity (Kv value).
* The closing point of the bypass on increasing main flow, and opening point of the bypass on decreasing main flow (switch point).
* The pressure drop in the main flow direction measured over the full operating range of the valve.
A flow test curve is supplied as part of the quality control documentation, which verifies that the valve performs to the specified requirements. The flow test medium is water, and the test curve is automatically corrected for actual service liquid if the specific gravity differs from that of water. The test data is permanently stored and can be referred to at any time following the flow test.
