The Auld Double Control Reducing Valve is ideal for applications requiring substantial pressure reductions, provided that the inlet pressure does not exceed 51 barG. This valve features a self-contained balance pipe, ensuring optimal performance with a closing pressure of +7% relative to the reduced pressure. Its balanced design remains unaffected by fluctuations in inlet pressure and responds instantly to changes in demand. The valve offers impressive reduced pressure accuracy of ±5% across a flow range from full flow down to 10% (with a turndown ratio of 10 to 1). Furthermore, its soft valve faces are well-suited for dead end conditions, and the single seat design facilitates precise control at low flow rates.
