PN16 DOUBLE REGULATING
BUTTERFLY VALVEDATA SHEET
PN16 Double Regulating Butterfly Valve
DescriptionFully lugged ductile iron Butterfly Valve with bonded EPDM linerand stainless steel trim, fitted with gear operator for infinitelyvariable settings and stainless steel memory stop feature (DRV) toprecisely set and retain the desired maximum opening positiondifferential pressure. Once set, the valve can be closed and re-opened accurately to the pre-set differential pressure.
Features and Benefits • Available in larger sizes up to and including 600mm diameter• Robust ductile iron Butterfly Valve for long service life• Easy to install and operate fully lugged gear operated Butterfly
Valve• Easy to set, positive position and reset memory stop feature• Accurate flow measurement and precise setting• Light weight and low cost
ApplicationThe Double Regulating Butterfly Valve is a commercially attractiveoption compared to traditional Globe-style Double RegulatingValves.The Butterfly Valve concept is space saving and easier to supportwhen weight is a concern.The Double Regulating Butterfly Valve is also available in large sizesup-to and including 600mm diameter.Pressure/Temperature plugs are provided to measure ΔP, which areto be installed in the pipework on either side of the valve.
