As a leading manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in engineering high-performance industrial valves for demanding global applications. Our Wafer Butterfly Valve PN10 is meticulously designed for the rigorous environments of bulk material handling and slurry pipeline systems. With an annual export value between US$1-1.5 million and a presence across continents from North America to Southeast Asia, we understand the critical need for reliable, low-maintenance flow control. This valve represents our commitment to providing cost-effective, durable solutions that enhance operational efficiency and minimize downtime in abrasive and corrosive media handling.
The PN10 Wafer Butterfly Valve is engineered to deliver superior shut-off and regulation in challenging applications. Its robust construction and thoughtful design translate into several key advantages for your operations.
- Optimized for Abrasive & Corrosive Media: The valve is specifically configured to handle powders, granules, and slurry mixtures with suspended solids, resisting wear and corrosion for extended service life.
- Compact & Lightweight Wafer Design: The wafer-style body fits between pipeline flanges, significantly reducing weight and space requirements compared to lug or flanged valves. This simplifies installation and lowers structural support costs.
- Bubble-Tight Shut-off Capability: Featuring a resilient seat (available in EPDM, NBR, or PTFE) that provides excellent sealing against the disc, ensuring minimal leakage in shut-off position, crucial for process control and environmental safety.
- Low Torque Operation & High Flow Efficiency: The streamlined disc design creates minimal flow turbulence and pressure drop, while the low-friction seat enables easy operation with manual levers, gear operators, or automated actuators.
- Versatile Actuation Options: The valve can be equipped with manual handles, gearboxes for larger sizes, or automated electric/pneumatic actuators, allowing seamless integration into both manual and fully automated control systems.
- Durable Construction: The body is typically cast from ductile iron for strength, while the disc is often stainless steel or coated carbon steel to withstand harsh media. This material combination ensures longevity.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a wafer design over a lug-style butterfly valve for my application?
A: The wafer design is lighter and more compact, fitting directly between two pipeline flanges with through-bolts. It's generally more cost-effective and ideal for systems where the valve is not required to be an end-of-line isolation point or support downstream piping weight, which is common in many bulk material and slurry lines.
Q2: Can this PN10 valve handle abrasive slurries effectively?
A: Yes, it is specifically recommended for such services. The selection of appropriate disc materials (like hardened stainless steel or coated options) and resilient seat materials helps resist abrasion. The streamlined disc also minimizes areas where solids can accumulate and cause wear.
Q3: Is the valve suitable for food-grade or potable water applications?
A: While the standard model is geared towards industrial bulk/slurry handling, it can be configured for such uses. This would involve specifying FDA-compliant seat materials (like specific EPDM grades) and ensuring all wetted parts meet relevant sanitary standards. Please inquire for these specific requirements.
Q4: What types of actuators are compatible with this valve?
A: The valve is designed with a standardized mounting pad compatible with a wide range of quarter-turn electric or pneumatic actuators from various manufacturers. We can supply the valve alone or as a complete actuated package based on your control needs.
Q5: What is the typical delivery lead time for standard sizes?
A: For standard sizes and materials within our DN50-DN600 range, lead times are generally competitive. Exact timelines depend on current order volume and specific configuration. We provide reliable estimates upon quotation to help with your project planning.
Q6: Do you offer any testing or certification with the valves?
A: As an ISO9001 certified manufacturer, our production follows strict quality control protocols. Standard valves undergo routine tests like shell tests and seat leakage tests. Additional certifications or third-party inspections (like API or CE) can be arranged upon request.
Q7: How do I select the right seat material (EPDM, NBR, PTFE) for my service?
A: The choice depends on the fluid's chemical composition, temperature, and presence of solids. EPDM is excellent for water, mild chemicals, and higher temperatures. NBR is suitable for oils and fuels at lower temperatures. PTFE offers superior chemical resistance and a wider temperature range but at a higher cost. Our technical team can assist you based on your media details.
Q8: Can the valve be repaired or maintained on-site, and are spare parts available?
A: Yes, the design allows for relatively easy maintenance. The seat can often be replaced without removing the valve body from the line by taking out the disc. Common wear parts like seats and seals are kept in stock for prompt supply, minimizing downtime.
