Circuit Definition & Working Logic (3-port / 2-port)

  1. 3-port Model (VM23x, Most Widely Used)

     -- Port 1(P): Main air supply inlet

     -- Port 2(A): Control signal output

     -- Port 3(R): Exhaust port

     -- NC Normally Closed Logic: Unactuated → P cut off from A, A connected to R; After actuation → P connects to A, A cuts off exhaust R

  2. 2-port Model (VM22x)

     -- Port 1(P): Fluid input

     -- Port 2(A): Control output

     -- Normally Closed: Air channel opens when pressed, cuts off immediately after release

Full Interchangeable Actuator Head Portfolio

  1. Roller Lever Type (For Stroke Limit Detection, Most Popular)

     -- VM231/221: Standard POM plastic roller lever

     -- VM231S/221S: Hardened steel roller for heavy-duty abrasion-resistant working conditions

     -- VM233/223: One-way anti-rebound roller lever

  2. Straight Plunger Type

     VM230/220: Standard straight push plunger

3. Pushbutton Type (For Manual Jog Operation)

     -- VM232/222: Flat standard pushbutton

     -- VM232Y/222Y: High-visibility yellow mushroom head for emergency stop

     -- VM232G/222G: Green indicator pushbutton

  4. Optional Special Actuators

     Hinge lever, toggle lever, lockable rotary knob, bidirectional lever and other customized trigger heads

 Model Code Explanation

   1. (Example: VM231-02-01S)

     -- VM231: 3-port circuit + roller lever actuator

     -- 02: Port thread size (Rc1/4=02; N02=NPT1/4; F02=G1/4)

     -- 01: Side port layout (00 = bottom port layout)

     -- S: Hardened steel roller (no suffix = standard POM roller)

     -- Color suffix: A=standard black; Y=yellow mushroom; G=green button

  2. Common Standard Models

     -- VM231-02-01A: 3-port, POM roller, Rc1/4, side port (universal general-purpose model)

     -- VM231S-02-01A: 3-port, hardened steel roller, Rc1/4, side port (heavy abrasion-resistant working conditions)

     -- VM230-02-00A: 3-port, straight plunger, bottom port

     -- VM232Y-02-01A: 3-port, yellow mushroom emergency stop button, side port

Core Product Advantages

     -- Medium high flow performance: Cv=0.87, nearly 8 times higher flow capacity than mini VM1 (Cv=0.11), perfectly matching medium-flow pneumatic circuits

     -- Universal Rc1/4 port: Standard mainstream thread size for automation equipment with excellent cross-model compatibility

     -- Reliable poppet sealing: Good air tightness, dust contamination resistance, fast response and extended service life

     -- Dual piping layout support: Side & bottom port options for flexible dense panel installation layout

     -- Complete actuator coverage: Roller lever, plunger, flat button and mushroom head available to cover mechanical limit, manual jog and emergency stop all scenarios

     -- Heavy-duty robust construction: Metal valve body; S suffix hardened steel roller optional for harsh industrial continuous operation

     -- Lubrication-free design: Low maintenance workload, clean and eco-friendly air circuit operation

Typical Application Scenarios

     -- Equipment stroke limit sensing: Cylinder / slide table full position detection with roller lever actuator

     -- Manual jog control: On-site machine commissioning and panel operation via pushbutton

     -- Safety emergency interlock: Yellow mushroom head for rapid air circuit cut-off

     -- Jig & fixture switching: Clamp / unclamp pneumatic loop control

     -- Automated production lines: Workstation position signal and mechanical safety interlock circuits

     -- Packaging, textile and printing machinery: High-frequency mechanical trigger control loops
