HZT037302100 Flap Valve | Key Component for the 25MBA Series Vacuum Sewage Pumps. EPDM One-Way Seal. Compatible with Mainstream Vacuum Systems (Marine, Yacht, and Land Vacuum Toilet).
1. Présentation du produit
The HZT037302100 flap valve is a key one-way opening and closing component in the 25MBA series vacuum sewage pumps. Installed between the suction chamber (HZT023280040) and the flap valve base (HZT023280061), it controls the one-way flow of black or gray water within the vacuum system. The valve automatically opens and closes based on pressure differentials, preventing wastewater backflow and gas re-injection, ensuring long-term stable system operation.
It is widely used in marine, yacht, passenger ship, and land-based vacuum toilets, serving as a key component for achieving high vacuum sealing and water-saving discharge.
2. Matériaux et savoir-faire
This component is compression-molded from high-performance EPDM (ethylene propylene diene monomer) elastomer, offering excellent resistance to seawater, blackwater, ozone, and aging, making it suitable for high-humidity, saline, and acidic/alkaline environments. After molding, it undergoes trimming and surface inspection to ensure uniform thickness and a smooth sealing surface, ensuring flexible opening and closing and reliable sealing. The EPDM material has a shore hardness of 60±5A, balancing flexible conformability with mechanical fatigue resistance, and can withstand frequent opening and closing conditions.
This component is precisely matched to the HZT023280061 valve seat, using a CNC-machined mold to ensure precise sealing contact. Together with the pump body (HZT023280010), suction chamber (HZT023280040), and pressure chamber (HZT023219100), it forms a complete sealed fluid channel.
3. Structure et caractéristiques techniques
The HZT037302100 flap valve features a curved sealing edge structure, enabling rapid opening at extremely low pressure differentials and rapid closing during vacuum recovery. Its unique geometry, optimized through fluid dynamics, reduces energy consumption and noise during opening and closing, improving system flow efficiency.
Technical Features:
a) One-way opening and closing structure, automatically controlled in response to vacuum pressure differential.
b) EPDM elastomer material is corrosion-resistant and aging-resistant, suitable for black water media.
c) High-precision fit with the HZT023280061 valve seat and HZT023280040 suction chamber.
d) Supports high-frequency opening and closing and long-term continuous operation, with a long maintenance interval.
e) Maintains sealing synchronization even when the pump body is dynamically balanced to G2.5.
4. Applications
This valve disc is not only suitable for 25MBA marine vacuum sewage systems, but can also be widely used in the following:
a) Vacuum sewage discharge systems for ships, yachts, passenger ships, and merchant/cruise/passenger vessels.
b) Vacuum wastewater transfer for offshore platforms, drillships, and FPSOs.
c) Recreational vehicles (RVs), portable toilets, and land-based vacuum toilet systems.
d) Blackwater/greywater vacuum collection and treatment systems.
e) Water-saving public health facilities, eco-friendly campsites, and urban underground sewage vacuum pipe networks.
This product features high water-saving efficiency, stable flow, and easy maintenance. It is compatible with major marine vacuum systems, including the interfaces and mounting structures used by common international brands.
