π‘ Three Highlights, Solving Three Pain Points
Highlight 1: Multi-Media Compatibility + Direct-Acting Structure
- Pain Point:β Traditional solenoid valves are typically suitable for only a single medium and require pilot pressure to operate.
- Solution:β Suitable for four media: air, water, oil, and steam (warm water). Direct-acting structure requires no pilot pressure and can operate at zero pressure differential, offering wide application scope.
Highlight 2: Compact Design + DIN Socket Wiring
- Pain Point:β Traditional solenoid valves are bulky, have complex wiring, and occupy more space.
- Solution:β Compact design with a narrow valve width. DIN socket connector wiring with overvoltage protection and indicator light ensures easy wiring and saves space.
Highlight 3: Aluminum Body + High Protection Rating
- Pain Point:β Ordinary valve bodies are prone to corrosion, and low protection ratings affect service life.
- Solution:β Aluminum body is lightweight and corrosion-resistant. Protection rating IP65 (dust-tight, protected against water jets) makes it suitable for damp and dusty environments.
π― Five Application Scenarios, Precise Matching
- “Industrial Automation Pneumatic Systems”: Controls air supply/exhaust for cylinders and pneumatic actuators, enabling automatic start/stop, direction change, etc., for equipment like production lines, packaging machines, and machine tools.
- “Water Treatment & Supply Systems”: Controls pump start/stop, pipeline on/off, such as for solar water heater filling control, water tank replenishment control, and irrigation systems.
- “Oil Circuits & Lubrication Systems”: Controls on/off for hydraulic and lubrication system oil lines, such as for machine tool lubrication, hydraulic station oil circuit switching, and fuel control systems.
- “Steam & Warm Water Control”: Controls on/off for low-pressure steam or warm water pipelines, such as in steam heating systems, warm water circulation systems, and sterilization equipment.
- “Vacuum System Control”: Controls on/off for medium-vacuum system pipelines, such as air supply/exhaust for vacuum suction cups or chucks, and in semiconductor equipment.

π οΈ Installation & Wiring: “Three Do’s and Three Don’ts”
β Three Do’s:
- Doβ install according to the arrow direction on the valve body, ensuring the IN port connects to upstream and OUT port to downstream. Horizontal installation is recommended with the coil vertical and facing upwards.
- Doβ install a filter upstream of the valve (add a regulator and lubricator if necessary) to ensure clean media. Thoroughly blow out pipelines before installation.
- Doβ tighten threaded connections with standard torque. For DIN socket wiring: connect power (+) to the + terminal, (-) to the – terminal, and ensure reliable grounding for the PE terminal.
β Three Don’ts:
- Do notβ exceed the maximum operating pressure of 1.0 MPa to prevent valve damage. Do not use media outside the specified range (e.g., corrosive liquids).
- Do notβ use in locations with water hammer, pressure surges, or excessive vibration. Install shock absorbers or pressure buffers if necessary.
- Do notβ use in high temperature (>60Β°C), highly corrosive, flammable/explosive, or excessively humid environments to prevent coil burnout or seal aging.
π Selection & Replacement Guide
- Need different body material?β β Choose VX223EGAXB (C37700 brass body) or VX223SGAXB (stainless steel body).
- Need different voltage rating?β β Choose VX223AGZXB (AC220V) or other voltage models (AC110V/DC12V, etc.).
- Need different port size?β β Choose VX213AGAXB (Size 1, 1/8β³) or VX233AGAXB (Size 3, 1/4β³, 5mm orifice).
- Need normally open (N.O.) valve?β β Choose the corresponding VX2 series N.O. model (check catalog for specifics).
- Need explosion-proof specification?β β Choose the VX2 series explosion-proof (Ex) model.
π ROI Analysis: Small Investment, Big Returns
Direct Economic Benefits:
- Multi-purpose Valve:β A single valve can handle four media (air, water, oil, steam), reducing spare part variety and inventory costs.
