How does the mechanical valve control the cylinder?

Generally, a solenoid valve is used to control the cylinder, and a relay circuit or controller is used to control the action of the cylinder. Usually, you can use Programmable controller PLC or timing program controller TPC to control. PLC is suitable for use by professional and technical personnel who can program. TPC timing program controller adopts table settings and does not require programming. It is suitable for use by personnel who are not familiar with programming. The main models of TPC timing program controller include TPC4-4TD, TPC8-8TD, TPC8-16TD, etc., which can realize automatic control of 4-way, 8-way, and 16-way cylinders.
