Innovative valve technology

WELCOME TO THE WORLD OF VALVE TECHNOLOGY Your partner for valve technology With a product range of several thousand valve types, we can offer you the perfect valve solution for almost every application. Our program of standard valves comprises over 900 valve combinations with four different types of control. In addition we offer a wide range of special valves which have been developed for specific usage in close coordination with our customers. In this, we can rely on extensive engineering competence and a proven modular system of components and options. We cater for customers in mechanical...

PILOT OPERATED SOLENOID VALVES Pilot operated valves are characterized by their simple, solid design. As sealing elements, the options are a diaphragm for pressure up to 20 bar or a piston for pressure up to 450 bar. Valves of this type need a pressure differential of the operating pressure for opening and closing. The minimum required pressure is specified as minimum pressure in the technical data sheet. The solenoid system only has a pilot function which relieves the main sealing element, i.e. the diaphragm or the piston. The medium pressure or the present pressure differential lifts the...

FORCE PILOT OPERATED SOLENOID VALVES Force pilot operated valves operate from 0 bar and can be installed where directly acting valves are used. However, beyond the range of the latter, they are supplied with smaller solenoids for higher pressures and larger nominal sizes. The actuator of a force pilot operated valve opens a pilot orifice and then lifts the sealing element from its seat directly or supported by the delta p of the operating pressure. The special feature of force pilot operated valves is that the actuator in the pressure range can open and close the valve without using the...

DIRECT ACTING SOLENOID VALVES Direct acting valves switch the sealing element directly via the magnetic system. In this case the seal usually needs to be lifted against the effective operating pressure from the seat simply by the actuator. A closing spring keeps the valve closed, supported by the medium pressure. The function depends on the size of the seat, the effective operating pressure and magnetic force. Application fields • low pressure gas supply for industrial and domestic applications in accordance with DIN-EN 161 • normally open • increased pressure range • position indicator •...

EXTERNALLY CONTROLLED VALVES (Externally) Pressure controlled valves are suitable for the control of gaseous, highly viscose, polluted and aggressive media. The actuator is separated from the medium. Neutral or liquid medium of 4-10 bar is necessary for the actuation. The pilot valve is available in standard supply voltages and can be delivered, by request. With compressed air being widely available, this type of valve control is preferable for problematic media. On average, only 0.4 liter of air are consumed for each switching. A return line for the control medium air is not necessary...
