As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance JIS F7481 5K/10K Pressure Rated Pneumatic Actuated Wafer Butterfly Valve. Established in 2016 and certified under the stringent ISO9001 quality management system, we combine advanced engineering with rigorous production controls to deliver valves that meet the demanding needs of global industrial applications. This valve is engineered for precise and reliable flow control in critical systems handling water, air, oil, gas, and mild chemical media, offering a robust solution for automated process lines.

Core Features & Technical Advantages:

JIS F7481 Compliance: Manufactured in strict adherence to the Japanese Industrial Standards (JIS F7481), ensuring dimensional interchangeability, reliable performance, and compatibility with piping systems following this widely recognized standard, particularly in Asian and international markets.
Dual Pressure Rating Options: Available in both 5K (approx. PN10) and 10K (approx. PN16) pressure classes, providing flexibility to match specific system pressure requirements, from moderate to higher-pressure applications.
Efficient Pneumatic Actuation: Equipped with a high-quality double-acting or spring-return (fail-safe) pneumatic actuator. This enables rapid, quarter-turn operation for open/close or modulating control, ideal for integration with PLCs and automated systems, ensuring remote operability and enhanced safety.
Robust Construction & Material Selection: The valve body is typically constructed from ductile iron (FCD450) with epoxy coating or cast steel (WCB) for higher strength. The disc is made from stainless steel (CF8/CF8M) or coated ductile iron, providing excellent corrosion resistance and durability. A variety of seat materials like EPDM, NBR, or PTFE are available to suit different media and temperature ranges.
Wafer Style Design: The compact wafer-type design allows for easy installation between two pipeline flanges using through-bolts, saving space and weight compared to lug-type valves, making it a cost-effective and space-saving solution.
Bubble-Tight Shut-Off: The precision-engineered disc and resilient seat combination ensures reliable, bubble-tight shut-off (when specified with appropriate seat material), minimizing leakage and ensuring process integrity.
Low Torque Operation: The streamlined disc design and low-friction seat contribute to low operating torque, allowing for the use of smaller, more economical actuators and reducing overall system energy requirements.
Versatile Applications: Designed for a broad spectrum of industries including water treatment, HVAC, power generation, chemical processing, food and beverage, pharmaceuticals, and general industrial air and liquid handling systems.

Frequently Asked Questions (FAQ):

Q: What is the main difference between the 5K and 10K pressure ratings?
A: The "K" rating denotes pressure class in JIS standards. 5K corresponds to a nominal pressure of approximately PN10 (10 bar), while 10K corresponds to approximately PN16 (16 bar). The valve body, disc, and seat are designed and tested to withstand the respective pressure levels.
Q: Can this valve be used for throttling or flow control, or is it only for on/off service?
A: While primarily designed for on/off service, when paired with a pneumatic actuator featuring a positioner (available as an accessory), it can be used for precise modulating or throttling control of flow rates.
Q: What are the available seat material options and how do I choose?
A: Common options include EPDM for water and general purposes, NBR for oil applications, Viton for higher temperatures and certain chemicals, and PTFE for aggressive chemicals. Selection depends on the fluid media, temperature, and required chemical resistance.
Q: Is the pneumatic actuator included, and what are the fail-safe options?
A: Yes, the valve is typically supplied as a complete package with the pneumatic actuator mounted. Fail-safe options (spring return) are available, which will automatically drive the valve to a pre-defined open or closed position upon loss of air supply, enhancing system safety.
Q: Are these valves suitable for food-grade or sanitary applications?
A: The standard valve is designed for industrial use. For food-grade or sanitary applications, specific modifications such as polished stainless steel internals, specific seat certifications (e.g., FDA-approved), and special cleaning procedures would be required. Please inquire for customizable sanitary versions.
Q: What is the lead time for standard sizes and configurations?
A: For standard sizes and common material combinations, lead times are generally competitive. Exact lead times depend on order quantity and current production schedule. We strive to provide accurate timelines upon receipt of your detailed inquiry.
Q: Do you provide technical support for actuator sizing and accessory selection?
A> Absolutely. Our technical team can assist with actuator sizing based on your operating pressure, required torque, and fail-safe needs. We also help select appropriate accessories like limit switches, solenoid valves, and positioners to ensure optimal system integration.
Q: How does the wafer-style installation work, and are gaskets required?
A> The valve is installed between two pipeline flanges. Through-bolts are passed through the bolt holes in the valve body and the flanges to clamp the assembly together. Separate gaskets are typically required for the flange faces; they are not integral to the valve.
