Shanghai Zhibang Valve Manufacture Co., Ltd., a professional manufacturer established in 2016, proudly presents the CB/T3265-94 Marine Level Gauge Self-Closing Valve DN25 PN0.1 Bronze Flanged Cock. This valve is specifically designed for reliable and safe operation in marine level gauge systems, offering a self-closing mechanism that enhances safety and prevents leakage. With our ISO9001-certified production and years of export experience, we ensure every valve meets the highest standards of quality and durability.
The CB/T3265-94 valve is built from high-quality bronze, providing excellent corrosion resistance in marine environments. Its flanged connection (DN25) and pressure rating of PN0.1 make it suitable for low-pressure liquid level measurement and control applications. The self-closing feature automatically shuts off the flow when the valve is released, minimizing the risk of accidents during maintenance or operation.

Q: Can this valve be used with other media besides water?
A: Yes, it is suitable for non-corrosive liquids such as fuel oil, lubricating oil, and hydraulic fluids, as long as the pressure and temperature are within the specified ranges. -
Q: What is the maximum working pressure?
A: The nominal pressure rating is PN0.1, which corresponds to 0.1 MPa (approximately 1 bar or 14.5 psi). For higher pressure applications, please consult our sales team for customized options. -
Q: Is the valve made of brass or bronze?
A: The valve is made of marine-grade bronze, which offers superior corrosion resistance compared to brass, especially in saltwater environments. -
Q: How do I install the valve?
A: The valve has flanged ends that bolt directly to matching flanges on the tank or piping. Ensure the gasket is properly placed and tighten bolts evenly. Refer to the installation manual provided with the product. -
Q: Does the valve require regular maintenance?
