Description

Overpressure inverters are especially useful equipment in double greasing lines to have the alternate operation of both lines automated. The equipment automatically pressurizes or relieves the flow of lubricant from one line to another depending on the predetermined pressure.

Design and principle of operation

This mechanically operated overpressure inverter is specially designed for installations of double lines with a medium pipe extension. The operation of this automatic overpressure reverser is similar to that of a two-way, two-position valve. When the predetermined pressure is reached, the inversion begins and opens an overpressure valve that controls a servo-controlled plunger, which in turn controls two others, one of them reversing the line.
