The direct acting spring loaded valve Mod. VSM FF automatically maintains and sustains a minimum
pre-set upstream pressure, discharging any excess downstream, regardless of variations in demand and
downstream pressure fluctuations. The piston actuated VSM FF will operate in derivation from the line, as
a protection from unwanted pressure rises and/or on the line as pressure sustaining valve.
Technical features and benefits
Entirely manufactured in stainless steel machined from a solid bar, without any welding.
Upstream pressure balanced piston technology.
Different spring ranges available.
Mobile block composed of stainless steel internals obtained by CNC to ensure the maximum accuracy
and sliding precision, this is to ensure the best reliability and to avoid friction.
Excellent resistance to cavitation and aggressive environments thanks to the design and the use of a
wide selection of gaskets made in special materials.

Applications
Water distribution systems.
Fire fighting systems.
Irrigation systems.
Buildings and civil installations whenever stainless steel is required or advised for project requirements.
Demineralized water and bottling plants.
Industry and cooling system
