General Information

In process plants for maintenance of working- or system-induced counter pressures as well as for reduction of pressure pulsation. The special diaphragm design and the interaction of diaphragm surface, valve piston and valve seat keep the working pressure at occurring counter pressure almost constant.

As pressurizing valve in metering pumps for guarantee of metering accuracy. In case of counter pressure at the secondary side the preliminary pressure and thus the metering quantity remain constant.

In all working areas where constant pressure is required.

Operating principle:

Does the working pressure or inlet pressure rise above a certain preset pressure value, the pressurized valve piston is lifted against the spring force. The valve opens and a pressure relief on the outlet side takes place. It closes as soon as the working pressure at the valve piston drops below preset spring force. If a system determined counter pressure arises at the secondary side this pressure has an impact on both simultaneously, namely under the diaphram and on the valve piston, i.e. the forces cancel out each other because the diaphragm and the valve mating surface / effective surface are the same size. The valve force and thus the working pressure remain nearly constant.
