    Hydraulic Control Valve is the most efficient valve for automatic operationof industrial and municipal distribution systems or any other system that requiresadjustable working conditions.

    The valve operates by pipeline water pressure and does not require any otherexternal energy source. The valve is a completely independent device and canbe installed at any location in the pipeline, provided there is just a minimumwater pressure allowing its operation. An operating piston surface double thesize of the sealing surface enables the control chamber movement towardsopening or closing with no external force or energy required.

    The G type is a piston actuated valve, which varies from 2 to 32 in a pressureranging from PN-16 to PN-64.Raphael G type, globe pattern, piston actuated control valves are a heavy

    duty, high pressure and large diameters throttling valves.As a piston actuated valve it is specially designed to withstand high restrictionlevels at a wide range of flow and diameters.

    The metal construction of the piston enables a smooth operation, with novibrations. Bronze and Stainless steel internal parts provide a cavitation resistancat very low flows keeping metal and iron parts of valves from being damage

    Low corrosion rates are obtainable due to high quality bronze and stainlessteel internal parts and high quality epoxy or enamel coating (Potable waterapproved).Regulation in high restriction rates is obtainable by a half restricted plug thatcombine a cost effective protection to seat and seal, keeping sensitive parts inthe valve from high velocity water passage.Globe pattern body construction gives equal wear for the control unit, thusprolonging its lifespan.

    RAPHAELS UCV - Universal Control Valve, is the perfect solution for today's and tomorrow's needs for variable, quick response,

    multi task applications of system management in waterworks infrastructure.RAPHAEL's UCV (Universal Control Valve) is specially designed to perform all control duties. The UCV's parameters can be easily changed by a simple controller access. Just by pushbotton one can set different values transmitted as Analog inputs (Pressure, Flow, Level, Temp., humidity,etc.), digital inputs (Maximum level, temp., overflow, saturation, etc.) or time related.

    T o avoid tamper and unauthorized changes in system's variants a password entry can be activated for different levels of interference (Operator's,Technician's or Programmer's level).

    Universal Control Valve

    A local display keeps operating team up-to-date with system's condition and performance. Local keypad allows instant changes in set points and parameters providing dynamic and adjustable on-line operating and system management.

    V alve programming can be made by any computer regardless of its physical location, and uploaded into the local control unit (installed on the Universal Control Valve) through the Controller's Network Ports. By pressing a botton the Universal Control Valve can perform a complete different set of control features.
