Diaghragm / Piston Constant Downstream Pressure Flow Control Regulating Control Valve (GL400X)

Constant Downstream Pressure  Flow Control ValveMODEL NO.: GL400XΔ 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.  Body & BonnetCast iron, Ductile iron, Cast steel, Stainless steel etcStemStainless steelDiscBrass, Carbon steel, Ductile iron etcSeatBrass, Stainless steel, Carbon steel etcSealingNBR etcDiaphragmNBR, EPDMPistonBrass, Carbon steel, Ductile iron etcPressure GradePN10, PN16, PN25, PN40, CL150, CL300SizeDN50-DN800Flange DimensionASME B16.42, BS4504, ISO2531, ISO7005 etc.Face to Face LengthANSI B16.11, API594,BS5155, ISO5752, DIN3352 etc.  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
