Automatic control valves H-FLUX 500 and 600 series

The Pietro Fiorentini H-FLUX range consist of a globe pattern hydraulically operated automatic control valves, namely 600 for the full bore and 500 for the reduced bore series, entirely produced in ductile cast iron and steel with internal components in stainless steel.
 

Piston actuated PN 40 class, the valve is designed to perform mainly pressure reduction and sustain. Each function is obtained simply by changing the circuitry and pilots, that can be combined together if needed.
 

All information herewith contained referring to operating principle, case studies and installation, are applicable to the H-FLUX 500 and 600 series unless otherwise stated.

• Body in ductile cast iron, PN 40 bar rated, globe pattern design in compliance with EN 1074 standards and available from DN 50 mm up to DN 200 mm.
• Designed to reduced head loss and minimize turbulence under a wide flow range.
• Throttling plug to ensure stability at low flow.
• Silent operation and absence of vibrations, suitable for buildings and urban applications.
• Excellent resistance to cavitation, thanks to the large expansion chamber and to PF solutions for flow regulation either AC, designed for stability also in case of low flow conditions, and the CP for extreme pressure ratio thanks to a double step through customised cages sliding one into the other.
• In-line serviceable from the top without having to remove the valve from the pipe.
• High quality materials which guarantee reliability for long lasting performances with internals all made in stainless steel.
