Diaphragm Control Valve
M3000
Automatic control valves, as described by EN 1074-5, “have the integral capability to control the function using energy from the conveyed water by adjusting the position of the obturator.
They can be directly operated, i.e. the force is applied (via a spring or diaphragm) directly to the obturator. They can be pilot operated, i.e. the force is applied through an adjustable pilot valve”.
This type of conveyed flow valves is the result of years of study, design and research carried out by T.I.S Nuoval over the years, both internally and directly on the plants.
These valves are available in sizes from DN50 to DN1000, flanges to EN 1092-2, with nominal pressures PN10 - PN16 - PN25.
These valves can be built as :
• Pressure reducing valves
• Pressure sustaining valves
• Altimetric valves
• Float controlled valves
DESIGN FEATURES
• Hydraulic testing according to EN1074-5;
• Compliance with EN 1074-5 and EN 1074-1;
• Parts in contact with the water comply with DM 174 of 6/04/2004 and KTW, DVGW W270, WRAS standards;
• Face to face according to EN 558 Series 1;
• Flanges dimensioned and drilled according to EN 1092-2;
• Internal/external FBE coating protection (Fusion Bonded Epoxy), blue RAL5015, 250 μm thickness.
OPERATIVE LIMITS
Valves are designed and manufactured to operate with drinking or industrial water without suspended solids. For any other use,
please contact the manufacturer.
