ASV Pressure maintenance valves type DHV

Valve designed for pipework systems where a constant pressure must be maintained "upstream" of the valve. It also functions as a check valve, as it is depressurised on the inlet side. The overflow function protects the system against overpressure. The valve is set with the adjusting screw and locked with the lock nut. Can also be equipped with a manometer outlet.
