TheXITA PVDF Manual Butterfly Valve is the fundamental solution for achieving direct and reliable flow control in demanding industrial environments. Unlike valves requiring an external power source, this series provides inherently safe, on-site control for hazardous acid/alkali pipelines through manual lever or gear operation, eliminating the need for electrical power.
By combining a corrosion-resistant Virgin PVDF body with an ergonomic, heavy-duty manual operator, it ensures precise flow on/off switching and modulation with zero risk of leakage. It is the ideal choice for chemical plants, semiconductor facilities, and water treatment systems that require a cost-effective, long-life fundamental control valve.
| Key Features & Technical Advantages ✔Exceptional Chemical Resistance: The PVDF Manual Butterfly Valve construction provides top-tier resistance to strong acids, alkalis, oxidizers, and solvents, ensuring longevity and reliability in the most aggressive chemical processes. ✔High Purity & Non-Contaminating: The inert, virgin PVDF material guarantees zero contamination of sensitive media, making it an essential and safe choice for semiconductor, pharmaceutical, and high-purity chemical applications. ✔Simple & Direct Control: Featuring a robust manual lever or gear operator, it provides immediate, fail-safe flow switching and modulation without the need for external power, offering ultimate control simplicity and reliability. ✔Reliable for Basic & Safe Operation: Designed for durability and leak-proof performance, it offers consistent and dependable operation in applications where manual control is preferred or required for safety and cost reasons. ✔Cost-Effective Foundation for Corrosive Service: With no need for actuators or complex control systems, it presents the most economical initial and long-term solution for flow control in corrosive environments compared to both automated valves and failing metal alternatives. |

FAQ
Q: How do you protect the actuator from acid fumes?
A: We utilize a double-sealing structure (O-rings + PTFE seat) to strictly isolate the medium, preventing corrosive vapors from entering the actuator housing.
Q: Can I integrate this valve with my PLC system?
A: Yes. Our valves come with standard wiring diagrams and support feedback signals, making integration into automated PLC systems seamless.
Q: What is the cycle life of the electric actuator?
A: The actuator is designed for high-frequency use, tested for over 50,000 cycles under rated load conditions.
