Proportional valves - Import export

Proportional regulation and control of high flow rates • Frictionless movement; • High flow rates; • Small footprint and size; • Low power consumption; • Pressure-balanced; • High dynamics; This valve combines the advantages of the Spider-μProp technology with the benefits of a pressurebalanced valve. Due to its large orifice, high flow rates are possible. Furthermore, the valve is distinguished by a high reproducibility of the lift-off point. The electrical power consumption lies thereby in the lowest range of the Plate Armature Technology. The compact design of the valve provides a variety of assembly options for different areas of application.

• Seat principle, direct actuated; • Frictionless movement Spider µProp-valves are real proportional valves, in which the armature stroke is proportionally defined by the infinitely-variable current applied. The constant ratio between armature stroke and flow rate thus allows variation of the flow rate by way of the applied current. Spider µProp-valves are like Spider on/off valves microvalves The anchors installed in the micro valves have the shape of a disk. In energized status, this so-called flat armature is pulled against the magnetic yoke component group. If the coil is deactivated, the leaf spring joined to the flat armature presses the seal positioned on the spring-armature assembly unit against the valve seat. These quick-acting valves owing to the small mass of the installed armature achieve switching phases in the millisecond range. These valves have a capacity of up to 4 billion actuations, depending upon operation mode.

Our assortment contains a range of pressure controllers for regulating the water pressure required for your application. In addition you will find filters for water treatments here. Water treatment is generally considered the targeted change of water quality. Here it is differentiated as to whether substances are removed from the water or added to the water. Water treatment represents an important process step in the production of drinking water for human use. Furthermore we have proportional control valves especially for use with water. There are various accessories and spare parts available for the mentioned products.

Simplicity without having to abandon the proved Herrmann Ultraschall standards – that are the characteristics of this machine type. Proportional valve technology and digital high-performance generators are basic equipment. A solid machine design with precision guiding rails and proved drive components are the foundation for quality and repeatable welds.

Robustness, accuracy, and simplicity are attributes characterizing this ultrasonic welding machine. The entry-level models already include a position measuring system and proportional valve technology as basic equipment. Moreover, password protection and part counter are standard. Precision guiding rails and reliable drive components ensure repeatable welds.

The name delivers what it promises. The ultrasonic welding machine HiQ VARIO can be configured to completely suit the customer’s needs. A large number of pneumatic drive modules with different strokes and cylinder diameters are available, always including the reliable proportional valve technology by Herrmann Ultraschall.
