Constant Downstream Pressure Flow Control Valve
MODEL NO.: GL400X
Δ The KARFAR model GL400X is popularly mounted in water distribution pipeline which needs flow control. This valve functions to maintain a stable flow rate preset by the pilot and reduce high flow rate to a preset data.
It turns the high upper-stream pressure into low pressure, so that the downstream flow will not be affected by the upper-stream changing pressure.
