| Flow Control Posiflow - 202 |
| Asco POSIFLOW proportional valves can be used in practically all applications in which the flow of a liquid or gas needs to be controlled. Since a single proportional valve replaces two or three conventional valves connected in parallel (NO / NC) to obtain low, medium or high flow rates, it is extremely cost and space saving. The core is guided by two rider rings so that the valve has low friction and high dynamic properties. An electronic control unit which is directly fitted onto the POSIFLOW increases its range of application even further. The integrated potentiometer is used to adjust minimum current, maximum current and frequency. A current ramp which can be altered by a potentiometer can also be connected. Thus slow changes in flow can be obtained in spite of sudden changes in the set-point. In case of set-points < 200 mV (<0.4 / 4.4 mA), the piloting current is completely switched off, so that the valve is without current (tightly closed function). |

| Flow Control Piezotronic - 630 |
| The Asco PIEZOTRONIC valve with proportional control is a high-tech solution designed in particular for those applications with an extremely low power consumption. It is suited for use with battery-operated equipment or in potentially explosive areas. Due to its long service life of 1 billion cycles it is also integrated in measuring systems such as medical equipment and gas analysers. It can even be powered by solar cells. Moreover, the PIEZOTRONIC valve is particularly suited for portable equipment because of its low weight. |

| Pressure Control Sentronic - 601 |
| The SENTRONIC valve with its internal control loop combines innovative pneumatic technology with the integrated analog electronics. This valve series allows for accurate adjustment of pressure, flow, force, speed, and linear or angular positions. All orifices have the same diameter for short response times when applying or exhausting pressure. The combined effect of all components assures a control behaviour at an extremely low hysteresis.. |

| Flow Control Pulstronic - 605 |
Unlike SENTRONIC valves, Asco PULSTRONIC valves operate with pulsed pilot valves which change the pressure in a control chamber. A pressure booster converts the pilot pressure into an outlet pressure with increased flow. The outlet pressure is measured with a pressure sensor and fed into the internal control loop. The set-point is established over the electrical plug-in connector as a standard signal [0 to10 V, 0(4) to 20 mA]..
The PULSTRONIC is particularly suited for pressure control applications with a constant flow, e.g. flow control over nozzles, turbine speed control, glue and lacquer dosing, pressure control of welding equipment. |

| Pressure and Flow Control Servotronic - 607 |
| Greater versatility in automated production processes: due to electronics, the new generation of Asco SERVOTRONIC products increases the range of application and performance of pneumatic components. The two SERVOTRONIC versions directly respond to all pressure and flow control needs and indirectly meet the performance in the control of physical variables, such as position, velocity, acceleration, force, mass etc..The combination of innovative pneumatic technology, high-precision mechanics and modern electronics allows for quick control of flow or pressure in a pneumatic actuating system in relation to a signal received from the controlling electronics. The SERVOTRONIC valve is used for flow control (proportional flow) and is provided with a precision-lapped spool and sleeve with hardened and tempered surface allowing for very high pulse frequencies at extremely short response times. The SERVOTRONIC valve has a constant air consumption |

| Flow Control Posimatic Compact Positioner - 290/390 |
| Asco Pressure operated 2 or 3-way proportional valves equipped with Posimatic or Compact Positioner offer a compact solution and are simple to install and easy to adjust. These valves can be used in many processes: sequential control systems, regulation in open and closed loop, flow or pressure control by servo-adjustment of the disc stroke. In installations where it is necessary to adapt process parameters directly on site, the Posimatic positioner mounted on a series 290 - 390, 2 or 3-way valve allows for a large range of flow characteristics. The system is easily programmable by 4 data entry keys, a pop up menu and an alphanumeric LCD screen. For machinery where space is at a premium, the Compact positioner, mounted directly on the valve, represents a simple and economic solution. Each valve equipped with a positioner is accompanied by a test certificate showing its calibration curve, guaranteeing the linearity of the characteristic "setpoint/ opening". |

| Sentronic D - 608 / 609 |
A new generation of Asco DIGITAL electronic pressure regulators:
DIRECT OPERATED : precise control and quick response times
DYNAMIC : short stabilising periods and low oscillation frequency
Gives you full control over the parameters used inside the valve: Manual control: the incorporated DISPLAY and the two push-buttons enable pressure readout, pressure manual set-point and LED diagnosis.
Computer control : Parameters features: this flexibility allows you to adapt the valve to your application and optimise its response time, accuracy and pressure control.
Valve diagnosis: read valve information such as serial number andvalve temperature, and watch the operation time using the operation counter. Read valve status and perform test functions for installation and service.
Storage of parameters: once the optimal parameters are determined, you can store them in a project file for your personal use, or you may forward the file to our Product Support Department for future serial production.. |
