        • BP1

        • Description:
          General_operational_description:

          The volume booster and proportional valve are fed by the supply
          pressure. When no command signal is applied the outlet pressure
          behind the booster is zero. When the command signal is increased the outlet pressure rises in proportion to it.

          Since the transmission ratio is not exactly 1 to 1, a slight
          pressure difference occurs between the outlet pressure of the
          proportional valve and the booster’s outlet on single loop systems.

          This can be balanced by a feedback signal (double loop), though.
          At single loop combinations the pressure difference between command signal and outlet pressure is being ignored because the proportional valve only refers to its own outlet pressure within the pilot chamber.
          The outlet pressure performance is dependent of the volume booster’s accuracy.

        • BP2

        • Description:
          General_operational-description:

          The volume booster and proportional valve are fed by the supply pressure. When no command signal is applied the outlet pressure behind the booster is zero. When the command signal is increased the outlet pressure rises in proportion to it. Since the transmission ratio is not exactly 1:1, a slight pressure difference occurs between the outlet pressure of the proportional valve and the booster’s outlet on single loop systems. This can be balanced by a feedback signal (double loop), though. Combinations with a second feedback have the possibility to balance pressure differences. For this a pressure transducer is installed in the outlet line of the booster. The electrical signal of the transducer is applied as a feedback signal onto the proportional valve. The valve detects any pressure differences and compensates them automatically. In high flow applications a pressure drop at the outlet of the pilot regulator is thus minimised.

      • Proportional Regulators

          • PQ1

          • Description:
            The pneumatic proportional valve produces outlet pressure in
            proportion to an electrical command input signal. It comprises
            a complete closed loop servo system consisting of valves,
            manifold, housing and electronic controls.

            Single_loop:
            Pressure is controlled by two solenoid valves. One valve
            functions as inlet control, the other as exhaust. The pressure
            outlet is measured by an internal pressure transducer which
            provides a feedback signal to the electronic controls. This
            feedback signal is compared with the command input signal.

            Any difference between the two signals causes one of the two
            solenoid valves to open, allowing flow into or out of the system.
            Accurate pressure is maintained by these two valves.

            Accuracy:
            Linearity / Hysteresis = ± 0.15 % FS
            Response sensitivity = < 0.1% FS
            Repeatability = ± 0.02% v.E
            Total accuracy = ± 0.2 % V.E.

            Supply_voltage: 15...24 V DC, residual ripple < 10%, with reverse voltage protection
            Command signal: 0-10V, 4-20mA as an option

          • PQ2

          • Description:
            The pneumatic proportional valve produces outlet pressure in
            proportion to an electrical command input signal. It comprises
            a complete closed loop servo system consisting of valves,
            manifold, housing and electronic controls.

            Double_loop:
            The servo valve expands in single loop operation by combining
            an additional feedback from an external sensing device with the
            internal transducer. The external sensor provides information
            on the control status.

            The PQ2 then compares the command signal with the second loop feedback signal. Should there be a difference in the signal
            comparisons, the servo valve will make adjustments to the
            internal loop to bring the system into balance. This provides
            accurate final outlet. The acceptance of electrical feedback from
            an external sensor enables precise control of conditions such as
            pressure, force, torque, position or flow.

            External_pressure_transducer:
            Any pressure transducer for 0-10 V and 4-20 mA output signal and
            suitable for 15-24V DC supply voltage can be applied.

            booster. The pressure is controlled by activating the
            solenoid valves, which apply pressure to the pilot side of
            the volume booster.

            Single_loop:
            Pressure is controlled by two solenoid valves. One valve
            functions as inlet control, the other as exhaust. The pressure
            outlet is measured by an internal pressure transducer which
            provides a feedback signal to the electronic controls.
            This feedback signal is compared with the command input signal.
            Any difference between the two signals causes one of the two
            solenoid valves to open, allowing flow into or out of the system.

            • PV21-PV40

            • Description:
              2-way proportional flow valve controls the volume flow of
              maximum 1185 l/min for air in proportion to the input signal
              of 0 to 10 V or 0/4 to 20 mA. The proportional valve and the
              electronic control unit are ordered separately.

              Product_selection:
              To achieve the best linear flow characteristics, it is advisable
              not to reduce the flow too much and to have enough pressure drop
              at the valve for good control.
              Reference_value: ∆p at the valve > 30% of the total pressure drop.

              Installation_hint:
              The nominal width of the orifice following the proportional valve
              should not be smaller than the nominal width of the valve.
              A constriction of the cross-section after the valve should be
              categorically avoided!

              Design:
              2-way proportional flow valve, normally closed during absence of
              current, with additional control module PVY in cable plug or
              - PVX in housing for DIN rail mounting

                          • Description:
                            The pressure booster doubles the system pressure of e.g. 5 bar
                            to an outlet pressure of 10 bar. The pumping force of two
                            cylindrical chambers compresses the air down to the set outlet
                            pressure within the third chamber while the fourth chamber is
                            vented. Upon reaching the outlet pressure it is turned off, when
                            falling below it is turned on automatically. Pressure boosters
                            are used for occasional demand of compressed air.

                            Media: lubricated and 50 µm filtered compressed air

                            Reversing, check and swichting valves provide for automatic control.
                            Life time approx. 20 million switching cycles.

                            Air tanks are recommended. They compensate pressure fluctuations and allow short-term high volume flows. See circuit.

                            Tank filling time is a measure of booster performance. To reduce
                            the filling time of the tank, it has to be prefilled with input
                            pressure P1. See circuit.

                              is ensured. Pressure drop amounts to 0.05 to 0.3 bar. In the
                              case of failure, the hose rupture valve blows off through a small
                              nozzle. After repairing the hose break, the hose rupture valve can
                              be set to zero again.

                              EN_ISO_4414-11.2010: According to EN ISO 4414-11.2010 the hose rupture valve protects individuals, systems and machines from injuries or damages caused by lashing hose lines in the event of hose breaks.

                              Function: The air passes the piston and continues through the seat.
                              The air stream is slowed down by means of lengthwise grooves on the piston surface. When the volume flow is too high, the air cannot pass the piston quickly enough, thus the piston will be pressed against the  spring. If the maximum admissible flow is exceeded, e.g. when the hose suddenly breaks, the air supply will automatically be shut off.
