Valve for drinking water and high to very high flow rates
Back pressure regulators XLC 320/420 (RP 116)
The back pressure regulator XLC 320/420 (RP 116)
is a pilot-controlled control valve consisting of main valve with position indicator, control unit, pilot valve, pressure gauge, stop valves and connecting pipes.
The main valve cone is fitted with a soft seal.
This valve which has been specially developed for drinking water applications, features an electrostatically deposited coating on internal and external surfaces and meets the KTW recommendation of the German Ministry for Health.
The control unit contains adjustable restrictors which allow the control characteristics of the pressure reducer to be matched to the system (closing, opening and response speeds).
The valve is completely piped. It does not require any additional pilot lines.
