As a professional valve manufacturer with a solid foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance CB/T465-1995 Cast Iron Gate Valve. Engineered for demanding industrial applications, this valve is designed to provide reliable shut-off and flow control in pipeline systems handling water, oil, and gas. Our commitment to quality, backed by ISO9001 certification, ensures every valve delivers durability and consistent performance under pressures of PN16 and PN25, making it a trusted component for infrastructure projects worldwide.
This flanged gate valve is constructed to meet the precise specifications of the Chinese national standard CB/T465-1995, guaranteeing interchangeability and compliance for a wide range of industrial installations. Its robust design is tailored for long service life with minimal maintenance, offering exceptional value for engineers and procurement managers seeking dependable fluid control solutions.
Key Product Features & Technical Advantages:
- Superior Material & Construction: The valve body and bonnet are manufactured from high-grade cast iron, providing excellent corrosion resistance and mechanical strength to withstand harsh operational environments and pressure surges.
- Dual Pressure Rating Flexibility: Designed to be suitable for both PN16 and PN25 pressure classes, offering versatile application across different system pressure requirements without needing multiple valve types.
- Reliable Sealing Performance: Features a precision-machined gate and seat arrangement. Options include resilient seated designs for bubble-tight shut-off or metal-to-metal seated designs for higher temperature applications.
- Robust Flange Connection: Standard flanged ends facilitate easy and secure installation into existing piping networks, ensuring a leak-free connection that is compliant with common flange standards.
- Efficient Flow Design: The full-bore design minimizes pressure drop across the valve when fully open, allowing for efficient fluid transfer and reducing pumping energy costs.
- User-Friendly Operation: Equipped with a handwheel for manual operation, designed for smooth opening and closing. Stem design prevents blow-out and ensures operational safety.

Frequently Asked Questions (FAQ)
Q1: What does the "CB/T465-1995" standard refer to?
A1: CB/T465-1995 is a Chinese national technical standard for iron gate valves. It specifies the design, dimensions, materials, testing, and marking requirements for these valves, ensuring product quality and interchangeability.
Q2: Is this valve suitable for steam applications?
A2: The standard cast iron construction with a resilient seat is typically for water, oil, and gas up to 120°C. For steam or higher temperature services, a valve with a metal seated design and confirmation of suitability for the specific temperature is recommended. Please inquire for high-temperature options.
Q3: What flange standards are the valves compatible with?
A3: The valves are manufactured with flanges compliant with common standards such as GB, ANSI, or DIN. The specific standard and facing (e.g., RF, FF) can be specified at the time of order to match your pipeline flanges.
Q4: Can you provide valves with different end connections, like threaded ends?
A4: The product described is specifically a flanged gate valve. For threaded or other connection types, we offer other valve models. Please contact us with your specific connection requirement.
Q5: What is the lead time for an order?
A5: Lead time depends on order quantity and specific specifications. For standard PN16/PN25 flanged valves, we often have stock or short production cycles. We provide accurate lead time estimates with every quotation.
Q6: Do you offer actuated versions of this gate valve?
A6: Yes, this cast iron gate valve can be fitted with electric or pneumatic actuators for automated control. Actuator selection depends on required torque, power supply, and control signals. This is a customizable option.
Q7: What quality certifications do your products have?
A7: Our manufacturing process is certified under the ISO9001 Quality Management System, which governs our production, inspection, and testing procedures to ensure consistent product quality.
Q8: What are the main packaging and shipping terms?
