• Springbonnet with adjustment screw
• Adjustment spring
• Valve system completewith diaphragm
• Pressure gauge
Materials
• Spherolitic cast iron housing
• Cast iron springbonnet
• Brass valve seat
• Brass pistonguide
• Cone up toDN150: brass, DN200: steal
• Spring steel adjustment spring
• EPDMdiaphragm

• EPDM sealingwashers
• Stainless steel screws and nuts
Application
Pressure reducingvalvesof this typeprotect installationsagainst
excessive pressure from the supply. They can be used for
household, industrial or commercial applicationswithin the range
of their specification.
By installingapressure reducing valve, pressurisationdamage is
avoided andwater consumption is reduced.
Theset pressure isalsomaintainedconstant, evenwhen there is
wide inlet pressure fluctuation.
Reduction of the operatingpressure andmaintaining it at a
constant level minimizes flow noise in the installation.
Special Features
• Non-rising stem for setting outlet pressure andposition indi-
cator on springbonnet (except for DN200)
• Theadjustment spring isnot incontactwith thepotablewater
• With outlet pressure gauge
• Inlet pressurebalancing - fluctuating inlet pressuredoes not
influence outlet pressure
• Powder coated inside and outside - Powder used is physio-
logically and toxicologically safe
• Reliable andproven
