Future Technology Already Proven C-Valves Piston Actuated Control Valves Control Valve Types for Water Supply Linear Motion Rotary Motion Globe Gate Diaphragm 1950 Pinch / Clamp Ball Valve Butterfly 1930 Plug Globe Angle Three-Way Multi-Level Knife Segmented Bore Full Bore Cylindrical Tapered Eccentric sphere Dark Blue represents the most common valves in water works and supply systems and their date of invention / modification Globe Diaphragm Butterfly Why Install a Control Valve? Prevent water hammer reduce pipe-bursts Prevent over-pressure reduce leakage Minimize network maintenance Prolong network life Supply accurate & stable pressure Maintain level prevent over-flow or running dry Limit flow Dynamic pressure management Why Replace a Control Valve? Past experience and maintenance direct us when choosing the valve type (Baumann) Cavitation Erosion Instability Corrosion Leakage and lack of sealing Vibration Reaction speed C-Valves - M1 Principles of Design Actuator is positioned parallel to the flow, and closes against the flow direction Wide range of pressures and flow rates Double chamber provides additional closing force N.C. and N.O. options Construction materials are highly resistant to cavitation, erosion and corrosion Full sealing Quick response Opening characteristic enables stable regulation even at low flow rates and high pressures.
