As a professional manufacturer with ISO9001:2015 certified quality management systems, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents the CBT4303 Wafer Butterfly Check Valve. Engineered for reliability and durability in demanding industrial applications, this valve is designed to prevent backflow and protect critical system components. With a robust bronze body and a rated working pressure of 150 PSI, it offers a cost-effective and high-performance solution for fluid control systems worldwide. Our decade of manufacturing expertise ensures that each valve meets stringent standards for performance and longevity.
The CBT4303 stands out due to its intelligent design and superior construction. Its core advantages and technical specifications are detailed below:
- Compact Wafer Design: The valve installs conveniently between two pipeline flanges, saving significant space and weight compared to lug-style or flanged-end check valves. This design simplifies installation and reduces overall system bulk.
- Efficient Flow Characteristics: The butterfly-style disc provides a streamlined flow path when open, minimizing pressure drop across the valve. This ensures efficient system operation and reduces energy consumption associated with pump work.
- Rapid Response & Tight Sealing: The disc is hinged and utilizes spring-assisted or weight-assisted closure (depending on configuration) to ensure swift shut-off upon flow reversal, preventing water hammer and protecting upstream equipment. The resilient seat ensures bubble-tight sealing in the closed position.
- Durable Construction: The main body is crafted from high-grade bronze (e.g., C83600 or equivalent), offering excellent corrosion resistance against water, oils, and many chemicals. Critical components like the disc stem are often made from stainless steel for enhanced strength and corrosion resistance.
- Versatile Application: This valve is suitable for a wide range of services including water supply, HVAC systems, irrigation, industrial processing, fire protection lines, and general service applications involving water, oil, gas, and other compatible fluids.

Frequently Asked Questions (FAQ)
-
What is the main advantage of a wafer-style check valve over other types?
The wafer design is significantly lighter and more compact. It installs directly between two flanges, eliminating the need for separate flange connections on the valve itself, which saves space, reduces weight, and often lowers installation cost. -
Can this valve be installed in any orientation?
For optimal performance and to ensure proper disc closure under gravity or spring force, it is recommended to install the valve in a horizontal pipeline with the flow direction upward. Installation in vertical lines or other orientations may be possible depending on the specific spring configuration; please consult our technical team for guidance. -
Is the 150 PSI rating a maximum or working pressure?
The 150 PSI refers to the working pressure rating. This is the continuous pressure the valve is designed to handle safely in normal operation. There is typically a higher test pressure and a safety margin above the working pressure. -
What fluids is the bronze body compatible with?
Bronze offers good resistance to corrosion from water, seawater, oils, fuels, and many non-aggressive chemicals. However, compatibility with specific aggressive chemicals, acids, or high-chloride solutions should be verified. Alternative body materials like stainless steel may be available upon request for more demanding services. -
How do I select the right seat material (EPDM, NBR, Viton)?
Seat material selection depends on the fluid media and temperature:
- EPDM: Excellent for hot water, steam (low pressure), and various chemicals. Good weathering resistance.
- NBR (Nitrile): Ideal for oils, fuels, and petroleum-based fluids.
- Viton (FKM): Suitable for high-temperature fluids, acids, and aggressive chemicals. Offers a wider temperature range.
-
Does the valve require regular maintenance?
Under normal operating conditions, butterfly check valves are designed for minimal maintenance. Periodic inspection of the external condition and listening for unusual noises during operation is advised. The internal components are not typically designed for in-line servicing; if failure occurs, valve replacement is standard. -
Are certifications or test reports available for this product?
As an ISO9001:2015 certified manufacturer, our production processes are rigorously controlled. Standard material certificates and factory test reports (e.g., shell test, seat test) can be provided upon request to meet your project or procurement requirements. -
What is the typical lead time for orders?
Lead times vary based on order quantity, size, and customization requirements. For standard sizes and configurations, we often maintain inventory for prompt shipment. We provide accurate lead time estimates with every quotation.
