As a dedicated manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Manual Marine Sewage Ball Valve. Engineered specifically for the demanding environments of maritime applications, this valve is designed to provide dependable shut-off control in shipboard sewage systems. With our ISO9001-certified production processes and years of industry experience since 2016, we ensure each valve meets rigorous standards for performance and durability, offering a robust solution for shipbuilders and marine engineers worldwide.
This valve is constructed to handle the challenging conditions of marine sewage, which often contains solids, debris, and corrosive elements. Its primary function is to isolate sections of the pipeline for maintenance or to control the flow of waste. The design prioritizes ease of operation, long service life, and minimal maintenance requirements, making it a cost-effective and reliable component for any vessel's sanitation system.
Key Features and Technical Advantages:
- Rugged Cast Iron Construction: The body is made from high-quality cast iron, providing excellent strength and corrosion resistance, which is crucial for withstanding the harsh, saline marine atmosphere and the abrasive nature of sewage.
- Full-Port Ball Design: Features a full-bore ball that minimizes pressure drop and allows for the smooth passage of solids and viscous fluids, reducing the risk of clogging in sewage lines.
- Robust Flanged Connection: The flanged ends (DN150) ensure a secure, leak-proof connection to the pipeline, facilitating easy installation and removal. The flanges are machined to precise standards for a perfect fit.
- Manual Lever Operation: Equipped with a sturdy manual lever for quick and easy 90-degree operation. The lever provides clear visual indication of the valve position (open or closed).
- Durable Sealing System: Utilizes high-performance seat seals (options like PTFE or NBR are available) that ensure a tight shut-off even after prolonged use and exposure to sewage.
- Standard Pressure Rating: Rated for PN1.6MPa, making it suitable for the typical pressure ranges found in marine sewage systems.

Frequently Asked Questions (FAQ):
Q1: Is this valve suitable for handling raw sewage with solids?
A1: Yes, the full-port ball design is specifically intended to allow the passage of solids and viscous materials commonly found in marine sewage, minimizing clogging risks.
Q2: What are the flange standards for this DN150 valve?
A2: The valve is typically manufactured with standard flange dimensions (like ANSI B16.5 or JIS/ISO). Please specify your required flange standard (e.g., PN16, ANSI 150) when inquiring, as it can be customized.
Q3: Can the valve be operated frequently?
A3: While designed for reliable operation, it is a manual valve best suited for isolation purposes rather than frequent throttling. For applications requiring regular cycling, please inquire about specific seat material options for enhanced cycle life.
Q4: What maintenance does this valve require?
A4: Maintenance requirements are minimal. Periodic inspection of the external condition and occasional lubrication of the stem (if applicable) are recommended. The robust seat design typically offers long life without adjustment.
Q5: Is the cast iron body resistant to seawater corrosion?
A5: The cast iron body offers good general corrosion resistance. For extended life in highly corrosive splash zones, external protective coatings or alternative materials like ductile iron can be discussed as options.
Q6: Do you offer actuators for this valve?
A6: This specific model is configured for manual operation. However, as a manufacturer, we can provide information on compatible pneumatic or electric actuators as an optional upgrade upon request.
Q7: What is the lead time for an order?
A7: Lead time depends on order quantity and specific customization. Standard specifications typically have shorter lead times. We provide accurate timelines upon receipt of your detailed inquiry.
Q8: What certifications accompany the valve?
A8: Our manufacturing facility is ISO9001 certified, ensuring a quality management system. Specific product certifications for marine applications (like from classification societies) can be discussed and provided based on project requirements.
