Maximum Pressure. MAX'MATOf, General Description This proportional valve in combination with the electronic control system allow for easy, swift and continuous regulation of the variables flow and pressure in gases and fluids with a high level of repeating accuracy. The valve is manufactured in sizes 10mm and 4mm which allows the application in a variety of control tasks in process engineering. The 3/3-Way-proportional valve is pilot operated and can be supplied with or without integrated pilot control hydraulic supply.

The MAXIMATOR proportional valve consists of the following main elements: The valve is a metallic seal 3/3 way - seat valve. The opening and closing of the valve takes place by means of a hydraulically actuated set piston. Valve box Attached control valve for actuation of the main valve Main valve unit with seals, piston and reset spring Pressure-resistant distance sensor to check main valve stroke • Pressure transducer (external) optional • Control electronics (external) optional An electrical signal is set by the control electronics as a reference. This target value may be the analog output...

Options Servo valve with control card Mounting versions The electronic control system with PID controller, actual value and setpoint input is supplied as a 19“card, tailored to the respective valve. The 3/3-Way Proportional valve is available as a tube connection or a plate connection version. The 19“ control card belonging to the valve contains the pressure and position controller for the valve and the amplifier for the pilot valve. The following figure shows the plate connection version of the 3/3-Way proportional valve mounted in a standard control block with pilot control hydraulic supply....

Connection plate Depending on the type (NG10 or NG4) and pressure range Maximator offers the right connection plate. The following table lists the order codes of the connecting plates. Hydraulic Units As an auxiliary power, hydraulic actuating power is required. There should be a minimum pressure of 120 bar used. To control the valve large quantities of hydraulic oil may be required for a short time. The flow rate depends on the task of regulation. Flow rates of up to 40 l/min may be required from the servo valve for a short time, but for each control cycle a maximum oil volume of approx. 56...
