pressure relay
DG3 type electro-hydraulic pressure relay
1. Overview
An electrical pressure relay is a product that closes or opens electrical contacts when subjected to a pressure load (DINISO 1219). It is typically used to issue electrical control commands or signals for the following working cycle (controlling the solenoid directional valve) or to terminate a cycle (cutting off the pump motor and placing the solenoid directional valve in zero position) when the set pressure value is reached or exceeded
