As a dedicated manufacturer with a foundation in quality since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents its precision-engineered CB/T4303 Butterfly Check Valve DN150 PN4.0MPa. This valve is crafted for industrial professionals seeking reliable, efficient, and durable flow control solutions. Our ISO9001-certified production processes ensure every valve meets stringent performance standards, offering a robust barrier against backflow in critical piping systems. With an annual export value reflecting our global reach across markets from North America to Southeast Asia, we combine technical expertise with practical design to deliver a product that enhances system safety and operational continuity.
Core Product Features & Technical Specifications:
- Wafer Design Advantage: The compact wafer-style body allows for installation between two pipeline flanges without requiring additional nuts or bolts on the valve itself. This design saves space, reduces weight, and simplifies installation and maintenance procedures.
- EPDM Seal Reliability: The valve utilizes an Ethylene Propylene Diene Monomer (EPDM) sealing element. EPDM is known for its excellent resistance to water, steam, many chemicals, and weathering, providing a durable and tight seal over a wide temperature range.
- Automatic Check Function: The butterfly disc design automatically closes upon flow reversal, preventing backflow. This non-return feature is crucial for protecting pumps, equipment, and maintaining desired flow direction without needing external power or control.
- High Pressure Handling: Rated at PN4.0MPa, this valve is engineered to withstand significant pressure in demanding industrial applications, ensuring system integrity under high-load conditions.
Detailed Technical Parameters:

Frequently Asked Questions (FAQ):
-
What is the main function of this butterfly check valve?
This valve primarily functions as a non-return or check valve. It allows fluid flow in one direction and automatically closes its butterfly disc to prevent reverse flow (backflow), protecting system components. -
How does the wafer design differ from a flanged valve?
A wafer valve is designed to be sandwiched between two pipeline flanges using the flanges' bolts. It does not have its own flange lips or require separate bolting, making it lighter, more compact, and easier to install than a traditional flanged valve. -
Is the EPDM seal suitable for hot water or steam?
EPDM rubber has good resistance to hot water and steam within typical temperature ranges for such applications. Specific temperature limits can be provided upon request based on your media conditions. -
Can this valve be used with aggressive chemicals?
EPDM offers resistance to many chemicals, but its compatibility depends on the specific chemical, concentration, and temperature. For aggressive media, alternative seal materials like FKM (Viton) may be available as a customization option. -
What does the pressure rating PN4.0MPa mean?
PN4.0MPa indicates the valve's nominal pressure rating is 4.0 Megapascals. This is the maximum pressure the valve is designed to withstand under normal operating conditions, ensuring safe performance in high-pressure systems. -
Are other sizes or pressure ratings available?
Yes, as a manufacturer, we typically produce a range of sizes (DN) and pressure ratings (PN). The DN150 PN4.0MPa is one standard model. Other specifications can be inquired for availability or custom manufacturing. -
What is the significance of the CB/T4303 standard?
CB/T4303 is a Chinese technical standard pertaining to butterfly valves. Manufacturing according to this standard ensures the valve meets defined dimensions, material, and performance criteria, providing a benchmark for quality and interoperability. -
How is the valve shipped and what are the delivery terms?
We ship from major Chinese ports including Shanghai, Guangzhou, Hongkong, and Beijing. Delivery terms (e.g., FOB, CIF) and lead times depend on order volume and destination, and can be confirmed during the quotation process.
