HZT-5775500 Pneumatic Control Mechanism – Marine Vacuum Toilet Spare Part
Le HZT-5775500 pneumatic control mechanism (commonly searched as 5775500 mécanisme de contrôle) is a critical pneumatic control component used in marine vacuum toilet systems.
It functions as the central control unit for the flushing process, coordinating pneumatic signals to operate the water valve et discharge valve in a controlled and repeatable sequence.
Designed specifically for marine and offshore environments, HZT-5775500 provides reliable performance in installations where electrical components are not preferred and long-term operational stability is required.
Product Overview
In a marine vacuum toilet system, the flushing process relies on precise pneumatic timing.
Le HZT-5775500 pneumatic control mechanism manages this process by converting the flush activation signal into a controlled air sequence that governs both rinse water admission and waste discharge.
As a core marine vacuum toilet spare part, HZT-5775500 is widely used in new installations, retrofit projects, and onboard maintenance programs where consistent flushing performance is essential.
Function Description – Pneumatic Flush Control
During operation, HZT-5775500 performs the following control functions:
- Controls water admission timing through the water valve
- Triggers discharge valve operation to release waste into the vacuum pipeline
- Maintains correct pneumatic sequencing between water rinse and discharge phases
- Supports adjustable flushing duration via pneumatic flow regulation components
This air-operated control logic ensures stable flushing performance while minimizing water consumption and system stress.
Key Features of HZT-5775500
- Fully pneumatic operation (no electrical components required)
- Reliable flush sequence control for marine vacuum toilet systems
- Designed for continuous shipboard and offshore service
- Compact construction for easy installation and replacement
- Maintenance-friendly design suitable for onboard servicing
If you are searching for marine vacuum toilet spare parts, unité de commande pneumatique, ou 5775500 mécanisme de commande pneumatique, HZT-5775500 represents the correct component category for flush control applications.
Compatible Components and System Reference (HZT Codes)
HZT-5775500 is designed to operate as part of a complete pneumatic flushing control system.
It is commonly installed together with the following components:
- Water valve: HZT-6542997 – Controls rinse water admission
- Discharge valve: HZT-6543002 – Controls waste discharge into the vacuum line
In many marine vacuum toilet configurations, the flushing system consists of:
HZT-5775500 (control mechanism)
- HZT-6542997 (water valve)
- HZT-6543002 (discharge valve)
This modular structure simplifies spare parts identification, ordering, and maintenance planning for ship operators and marine service companies.
Flush Duration Adjustment (Jet Carrier Reference)
Flushing duration in marine vacuum toilet systems may vary depending on vessel operating conditions and water supply characteristics.
HZT-5775500 supports flush duration control through pneumatic jet carrier selection.
Typical jet carrier references include:
- HZT-5778004 – Extra long flushing period
- HZT-5778000 – Long flushing period
- HZT-5778001 – Normal flushing period
- HZT-5778002 – Short flushing period
Selecting the appropriate jet carrier allows optimization of flushing performance while maintaining system stability.
