As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our CB/T3591 DN300 Gate Valve with Handwheel Actuation. Engineered for reliability and durability in demanding industrial environments, this valve is a cornerstone for flow control in pipelines transporting water, oil, and gas. We combine rigorous manufacturing standards, backed by our ISO9001 certification, with a deep understanding of global market needs, exporting to over a dozen regions worldwide. Our commitment is to deliver valves that offer not just functionality but long-term operational stability and cost-effectiveness for your projects.
This DN300 Gate Valve is designed for precise on/off control in large-diameter piping systems. Its robust construction ensures minimal pressure drop when fully open and a tight seal when closed, making it suitable for a wide range of industrial applications. The handwheel actuation provides a reliable, manual operation method, ideal for situations where power sources are unavailable or for routine isolation purposes.
Key Features & Technical Advantages:
- Standard-Compliant Design: Manufactured in strict accordance with the CB/T3591 standard, ensuring dimensional accuracy, material integrity, and performance consistency expected in professional industrial settings.
- Robust Construction: The valve body, typically crafted from high-grade cast steel or ductile iron, offers excellent resistance to mechanical stress and corrosion, contributing to an extended service life.
- Efficient Flow Path: Features a full-bore design that minimizes flow resistance and pressure loss, allowing for efficient fluid transport and reducing energy costs over time.
- Reliable Sealing Mechanism: Utilizes a wedge or parallel slide gate disc paired with resilient or metal seats (options available) to achieve bubble-tight shut-off, preventing leaks and ensuring system safety.
- User-Friendly Handwheel: The ergonomically designed handwheel allows for smooth operation, even under higher differential pressures. It provides clear visual indication of the valve position (open/closed).
- Versatile Application Scope: Suitable for a broad spectrum of media including clean water, wastewater, oil, gas, and other non-aggressive fluids across industries like power generation, water treatment, petrochemical, and general plant utilities.
- Customizable Configurations: While the standard design complies with CB/T3591, we offer customization options such as specific material grades (e.g., WCB, CF8M), different pressure classes (PN10, PN16, PN25), and alternative face-to-face dimensions to meet specific project specifications.

Frequently Asked Questions (FAQ)
-
Q: What does "CB/T3591" signify for this gate valve?
A: CB/T3591 is a Chinese national standard for marine and industrial valves. It specifies requirements for design, materials, dimensions, testing, and marking. Compliance ensures the valve meets recognized technical criteria for performance and safety. -
Q: Is this valve suitable for throttling flow control?
A: Gate valves are primarily designed for fully open or fully closed service (on/off). Using them for frequent throttling can cause vibration, seat, and disc wear, leading to premature failure. For flow regulation, we recommend using control valves or globe valves. -
Q: Can you provide valves with different end connections besides flanged?
A: Yes. While flanged ends are standard for DN300 size per the CB/T3591 standard, we can manufacture valves with other connection types like butt-weld ends upon request for specific project needs. -
Q: What are the available material combinations for the body and trim?
A: Common combinations include a WCB (carbon steel) body with stainless steel trim for general service, or full stainless steel (CF8/CF8M) for corrosive applications. We offer various material grades; please provide your service conditions for a precise recommendation. -
Q: What is the lead time for an order of these DN300 valves?
A: Lead time depends on order quantity, specific configuration (standard vs. customized), and current production schedule. Generally, for standard configurations, we can offer competitive lead times. Please inquire with your required quantity for an accurate estimate. -
Q: Do you offer any warranty on your gate valves?
A: Yes, we provide a standard warranty against manufacturing defects. The specific warranty period and terms are provided with our commercial quotation and are based on the application and agreed specifications. -
Q: Are your valves tested before shipment?
A> Absolutely. Each valve undergoes rigorous pressure testing, including shell tests and seat leakage tests, in accordance with relevant standards to ensure integrity and leak-tight performance before it leaves our factory. -
Q: Can the handwheel be replaced with a gear operator or actuator?
A> Yes. While this model is specified with a handwheel, we can design it to be adaptable for future actuation. Some designs allow for easy retrofitting with gear operators or pneumatic/electric actuators. Please discuss this requirement during the inquiry stage.
