1. Basic Parameters
Series: 551 Series (i.e., Model 8551). This series features compact solenoid valves with 1/4-inch NPT and BSP connections.
Voltage: Common 24V DC (refer to the 24V marking on models in the same series, such as VCEFCMG551H401MO).
Construction: Three-way, in-line, single-control pneumatic directional control valve. This design incorporates a rigid T-ring seal and flexible O-ring for bubble-tightness and dirt resistance.
2. Core Features
Environmental Adaptability: Suitable for harsh environments such as chemical, refining, food and beverage, and life science processing. Global Ex certifications (such as ATEX, IECEX, and UL) ensure explosion-proof safety.
Mounting Options: Supports two mounting options: direct mounting to an actuator with a NAMUR interface according to VDI/VDE3845 standards, or threaded mounting on a pipeline. The exhaust port can be piped for enhanced environmental resistance. III. Application Scenarios and Purchasing Recommendations
1. Typical Applications
Industrial Automation Control: Used for on/off control of media (air or inert gas) in pneumatic systems, such as valve opening and closing, cylinder actuation, etc.
4. Pneumatic Control Valve
Harsh Environment Operation: Its dirt resistance and explosion-proof properties ensure stable operation in environments with corrosive gases, dust, or moisture.
