Working Principle 

1. 5900200 Push Button

Press the EVAC button to send electrical trigger signal to vacuum control unit; system activates vacuum pump and water supply to complete toilet flushing. The molded logo cap ensures stable pressing feedback for long-term marine frequent use.

2. 5959902 Mini Check Valve

One-way internal diaphragm structure: Air & sewage can only flow toward vacuum tank, automatically close the channel when pressure reverses. Effectively stop sewage backflow, vacuum loss, and pipeline blockage caused by reflux.

3. 6542998 Solenoid Valve

Cooperate with vacuum control circuit: Open valve to supply flushing water when receiving flushing signal; cut off water flow automatically after flushing cycle ends. The built-in blue silicone gasket eliminates water seepage under ship sway & vibration.
