Automatic control valve
diaphragm actuated
Automatic control valves, as described by EN 1074-5 norm:
“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”.
M2000/M3000-Type automatic control valves are part of TIS Nuoval products range for water supplies, irrigation and fire protection. This type of T-pattern flow valve is the result of years of study, design, and development by T.I.S.
These valves are available in sizes from DN50 to DN1200 flanged according to EN 1092-2, with nominal pressures of PN10 - PN16 - PN25. The valves are hydraulically actuated, with a metal shutter released by the action of pressure on a diaphragm. The use of a particularly highperformance sealing gasket developed by T.I.S. ensures an excellent seal and extended duration even under very demanding operating conditions.
The M3000 series valves are standard passage (seat size smaller than the nominal diameter of the valve). This offers intrinsically superior regulation and dissipation capacity.
The M2000 series valves are full passage (seat size equal to the nominal diameter of the valve). This generates a very limited pressure drop with the shutter fully open.
