As a professional manufacturer with ISO9001 certified processes, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable and durable fluid control solutions for demanding marine environments. Our Marine Sewage System Ball Valve DN200 PN1.0MPa with EPDM Rubber Seal is engineered to meet the rigorous challenges of shipboard wastewater management. With a proven track record of exporting to key markets across the globe, including North America, Europe, and Southeast Asia, we understand the critical need for valves that offer robust performance, long service life, and minimal maintenance. This valve represents our commitment to quality, designed to ensure secure shut-off and smooth operation in marine sewage lines, protecting your vessel's systems and the environment.
This DN200 ball valve is a cornerstone for efficient and safe marine sewage handling. Its design focuses on durability and reliable sealing under the specific conditions found onboard ships and offshore platforms.
Key Features & Technical Advantages:
- Superior Seal Integrity: The valve features an EPDM (Ethylene Propylene Diene Monomer) rubber seat, chosen for its excellent resistance to abrasion, aging, and a wide range of chemicals commonly found in sewage and wastewater. This ensures a bubble-tight seal, preventing leaks and backflow.
- Robust Construction: The valve body is manufactured from high-grade carbon steel, providing the necessary strength and corrosion resistance for marine applications. The full-port design minimizes pressure drop and allows for efficient flow of fluids with suspended solids.
- Precise Operation: Equipped with a manual lever actuator, the valve offers quick and easy 90-degree operation for open/close control. The design ensures clear visual indication of the valve position.
- Designed for Marine Service: Every component is selected and tested for performance in saline, humid, and variable temperature environments typical of marine operations.
- Easy Integration: The flanged connection (DN200) conforms to standard dimensions, facilitating straightforward installation into existing pipeline systems.

Frequently Asked Questions (FAQ)
-
Why is EPDM rubber specified for the seal in this marine sewage valve?
EPDM rubber offers outstanding resistance to water, steam, mild chemicals, and weathering. It performs well across a broad temperature range and is highly resistant to the abrasive and sometimes corrosive nature of marine sewage, ensuring long-lasting seal integrity. -
Is this valve suitable for use with seawater directly?
Yes. While designed for sewage systems, the materials (carbon steel body with appropriate coating/finish and EPDM seal) are selected to withstand exposure to seawater. However, for continuous seawater service, confirming specific material grades is recommended. -
Can this valve be supplied with different end connections, like threaded ends?
Our standard offering for DN200 size is flanged connections for robust, leak-proof joining in pressurized pipelines. Other connection types may be available as a customization option; please inquire for specific requirements. -
What is the expected service life of the EPDM seal under normal operating conditions?
The service life depends on operating frequency, fluid composition, and pressure/temperature cycles. Under standard marine sewage conditions and with proper operation, the EPDM seal is designed for extended service, often lasting several years before maintenance is needed. -
Do you provide certifications or test reports for this valve?
As an ISO9001 certified manufacturer, we conduct rigorous quality checks. Standard material certifications and factory test reports (such as shell test, seat test) can be provided upon request to support your procurement and classification society requirements. -
Is the valve suitable for both above-deck and below-deck installation?
Yes, its construction is suitable for various marine environments. However, for exterior, exposed locations, additional weather protection for the operating mechanism might be advisable depending on specific conditions. -
What is the lead time for an order of this DN200 ball valve?
Lead times vary based on order quantity and current production schedule. We maintain efficient production and inventory practices to ensure timely delivery. Specific lead times will be confirmed with your order quotation. -
Do you offer other pressure ratings or sizes for marine sewage ball valves?
Absolutely. As a manufacturer, we produce a wide range of sizes (DN15 to DN500) and pressure classes (PN6 to PN25) with various seal materials. We can discuss the optimal valve for your specific application needs.
