As a professional manufacturer with ISO9001 certification since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable marine fluid control solutions. Our CBM1065-81 Marine Sounding Valve with Manual Override is engineered for critical applications where safety and operational continuity are paramount. This valve is designed to offer dependable liquid level measurement while incorporating a crucial manual override mechanism for emergency scenarios, ensuring vessel safety and compliance with marine operational standards. We have successfully exported our products to markets worldwide, including North America, Southeast Asia, and Europe, building a reputation for durability and performance in demanding maritime environments.
Core Design & Technical Specifications:
The CBM1065-81 is a robust sounding valve specifically built for marine service. Its primary function is to allow for the manual checking of liquid levels (like bilge water, ballast, or fuel) in tanks. The integrated manual override feature is its defining characteristic, enabling crew to operate the valve directly in case of power failure or control system malfunction—a critical safety backup.
- Dual-Operation Design: Functions as a standard sounding valve for routine checks and transforms into an emergency manual valve when needed.
- Corrosion-Resistant Construction: Available in marine-grade materials like stainless steel, bronze, or brass to withstand saltwater, humidity, and harsh offshore conditions.
- Positive Seal Mechanism: Ensures leak-proof operation when closed, preventing unwanted discharge or contamination.
- Ergonomic & Clear Operation: The manual override is designed for intuitive use under stressful conditions, with clear open/close indicators.
- Versatile Installation: Compatible with various tank configurations and piping layouts common in shipbuilding.

Frequently Asked Questions (FAQ):
-
Q: What is the primary use of a "sounding valve" on a ship?
A: A sounding valve is used to manually check or measure the liquid level inside a tank (e.g., ballast, bilge, freshwater, fuel) by allowing a small sample to flow out, indicating the level. It's a fundamental tool for tank management. -
Q: When would the manual override on this valve be used?
A: The manual override is an emergency feature. It is used if the primary automated or remotely controlled valve system fails, loses power, or malfunctions, allowing the crew to manually open or close the valve to control tank drainage or filling. -
Q: Can this valve be made from materials other than stainless steel?
A: Yes. While stainless steel 316 is standard for excellent corrosion resistance, we also offer it in marine-grade bronze or brass. The material can be selected based on the fluid media and specific environmental conditions. -
Q: Is the CBM1065-81 suitable for high-pressure applications?
A: The standard pressure rating is PN16/Class 150. For higher pressure requirements, we can provide customized versions with different body designs and seal materials. Please specify your operating pressure during inquiry. -
Q: How do I specify the connection type I need?
A> You need to provide the pipe size (e.g., DN65, 2.5") and the connection standard (e.g., flange PN16, NPT thread). We support common marine piping standards, and technical drawings can be exchanged for confirmation. -
Q: Does this valve require special maintenance at sea?
A: It is designed for low maintenance. Periodic visual inspection for leaks and occasional exercise (opening/closing) of the manual mechanism to ensure free movement is recommended as part of routine ship maintenance schedules. -
Q: Can you provide certifications for the materials used?
A: As an ISO9001 certified manufacturer, we maintain material traceability. Material test certificates (MTC) for the valve body and critical components are available upon request. -
Q: What is the typical lead time for an order?
A: Lead time depends on order quantity and customization. For standard models, it is generally shorter. We ship from Shanghai, Guangzhou, Hong Kong, or Beijing ports to facilitate timely delivery to your location.
