Quick Exhaust Valve KKP-8
Introduction
It is used for the rapid exhaust of the air circuit, so that the cylinder can be quickly returned. When the air supply is cut off, a reverse pressure difference is generated, and the exhaust port of the quick exhaust valve is pushed open to achieve rapid exhaust.
