304 Body-304 Disc-PTFE Seat Pneumatic Triple Unit Wafer Butterfly Valve
Product Introduction
The 304 Body-304 Disc-PTFE Seat Pneumatic Triple Unit Wafer Butterfly Valve is designed for high-precision industrial fluid control. Constructed with full 304 stainless steel body/disc and PTFE seat, it integrates a pneumatic actuator and triple unit (air filter, limit switch, solenoid valve) for rapid cycling and flow regulation. Ideal for pharmaceutical, food processing, and electronic chemical applications requiring frequent operation, it operates from -30℃ to 120℃ (PTFE seat rated for 120℃) with pressure up to PN16/ANSI 150.
Product Advantages
- Rapid Response: Solenoid valve actuation <0.2 seconds; limit switch provides real-time status for efficient control.
- Easy Maintenance: Wafer design allows quick disassembly without pipe removal; PTFE seat service life extends to 3-5 years.
- Energy Efficiency: Stable pneumatic operation with triple-unit synergy reduces energy consumption by 25%.
- Media Adaptability: Ensures reliable performance in ultra-pure water, chemical solutions, and more.
Product Features
Corrosion-Resistant Build
304 stainless steel body/disc without polishing, suitable for non-sanitary environments.
01
Precision Pneumatic Control
Air filter (clean air supply), limit switch (position signal), and solenoid valve (instant response) enable seamless automation integration.
02
Space-Saving Wafer Design
Lightweight body reduces pipe load; double-offset structure minimizes torque while maintaining sealing integrity.
03
Chemical-Resistant PTFE Seat
Withstands aggressive acids, alkalis, and solvents, ensuring elasticity at 120℃.
04
Stem Customization
Standard options include galvanized steel stem (basic corrosion resistance), 2Cr13 stem (wear resistance), or 304 stainless steel stem (versatile durability).
