Electropneumatic valve for power cylinder drive - has spring loaded closure elements in each branch channel

摘要

An electropneumatic valve comprising a body with branching off channels for the delivery of compressed gas to the actuating mechanisms and its discharge into the atmosphere. Each branch of the channel for the delivery of compressed gas is provided with a spring-loaded closing element. To ensure successive opening of the closing elements and for the delivery of compressed gas to, and its discharge from, the actuating mechanisms, the stiffness of the springs of the closing elements is different. This allows a single valve to be used to control the operation of two actuating mechanisms.
