π‘ Three Highlights Solving Three Pain Points
- Highlight 1: Compact & Direct Piping, Saves Spaceβ Pain Point:β Traditional solenoid valves are bulky and difficult to install in space-constrained equipment. Solution:β Flat, box-shaped design with a body width of only 10mm. Direct piping installation requires no manifold, saving significant space. Ideal for automated equipment with space limitations.
- Highlight 2: Low Power + Power-Saving Circuit, Energy Efficientβ Pain Point:β High power consumption of traditional valves leads to significant long-term electricity costs. Solution:β Power-saving circuit design consumes only 0.1W, saving about 75% power compared to standard types (0.4W), significantly reducing long-term operating costs.
- Highlight 3: High Flow + Fast Response, Excellent Performanceβ Pain Point:β Small flow capacity and slow response of standard valves affect equipment cycle times. Solution:β Flow coefficient Cv = 0.33 (PβA/B), Conductance C = 1.5 dmΒ³/(sΒ·bar), response time ~26 ms. Provides excellent flow control capability and fast response for high-flow, high-speed applications.
π― Five Application Scenarios, Perfectly Matched
- Directional Control for Automated Production Lines:β Controls reciprocating motion of cylinders and actuators in automotive, electronics manufacturing, etc., for gripping, handling, and positioning workpieces.
- Pneumatic Control for Packaging Machinery:β Controls actions like material conveying, sorting, and marking in packaging machines, ensuring precision and stability.
