HZT-6542997 / HZT-5774002 Pneumatic Water Valves – Marine Vacuum Toilet Spare Parts
En HZT-6542997 y HZT-5774002 water valves are pneumatic rinse water control valves used in marine vacuum toilet systems.
Both models perform the same core function: regulating the admission of rinse water during the flushing cycle to ensure stable, repeatable flushing performance.
These water valves are widely used as marine vacuum toilet spare parts in shipboard and offshore sanitary systems where air-operated flushing control is preferred.
Product Overview
In a marine vacuum toilet system, correct water admission is critical to achieving an effective flush while maintaining system stability.
En HZT-6542997 / HZT-5774002 pneumatic water valves are designed to open and close in response to pneumatic signals generated by the control mechanism.
By delivering a controlled amount of rinse water at the correct moment in the flushing sequence, these valves support consistent performance and reduced water consumption.
Function Description – Rinse Water Control
During the flushing process, the pneumatic control mechanism sends an air signal to the water valve.
Upon receiving this signal, the HZT-6542997 or HZT-5774002 water valve opens to allow rinse water to flow into the toilet bowl.
Their primary functions include:
- Controlling rinse water admission timing
- Supporting stable and repeatable flushing cycles
- Operating fully pneumatically without electrical power
- Ensuring consistent water delivery in marine environments
Key Features
- Fully pneumatic water valve design
- Designed specifically for marine vacuum toilet systems
- Stable operation under continuous shipboard use
- Corrosion-resistant construction suitable for marine environments
- Maintenance-friendly design for onboard servicing and replacement
Whether selecting HZT-6542997 or HZT-5774002, both valves provide reliable rinse water control for marine sanitary installations.
