Category buying guide
Start valve selection from function, port size, and response.
Pneumatic valve selection starts with circuit function.
Before RFQ
Keep the selection grounded in working details.
- Valve function
- Port thread and tube size
- Voltage and coil type
- Pressure range and medium
Series comparison
Choose the valve by circuit job, not by appearance.
Fluid solenoid valves handle utility media, air-control valves shape exhaust, startup, vacuum, or air-logic behavior, operator valves handle manual input, and regulation valves tune speed, check flow, drains, and boosters.

Choose by valve task
Start with the control job the valve must do.
Pick the closest use case, then confirm valve function, port size, coil voltage, pressure, medium, mounting, and connector details before RFQ.
Control cylinder motion from an electrical signal.
Solenoid valves are the common path when a PLC, relay, or controller needs to switch air to an actuator.
Recommended option
Directional solenoid valve with confirmed function, coil voltage, and port thread.
- Valve function
- Coil voltage
- Port size
- Manifold or individual mount
Smooth or slow cylinder movement.
Flow controls can stabilize motion, but the direction of controlled flow should be chosen with the actuator behavior in mind.
Recommended option
One-way flow control valve or precision speed controller.
- Tube OD
- Thread standard
- Meter-in or meter-out
- Adjustment access
Give an operator direct pneumatic control.
Manual, foot, and mechanical valves are useful when the machine function is intentionally human-triggered.
Recommended option
Manual lever, foot pedal, or mechanical button valve with correct porting.
- Actuation style
- Return style
- Number of positions
- Panel or inline mount
Common valve uses
Where pneumatic control components are installed.
Valve use 01
PLC-controlled actuator circuits
Use solenoid valves and manifolds when a PLC output must switch a cylinder, gripper, clamp, or rotary actuator between defined positions.
- Choose 3/2, 5/2, or 5/3 function
- Match coil voltage and connector
- Confirm port size and manifold pitch
Valve use 02
Cylinder speed and stop tuning
Use one-way flow controls, speed controllers, and quick-exhaust valves when a cylinder moves too fast, stalls, or needs smoother end-of-stroke behavior.
- Choose meter-in or meter-out control
- Match tube OD and thread
- Keep adjustment access outside guards
Valve use 03
operator and maintenance controls
Use manual, foot, mechanical, check, and shut-off valves when a circuit needs local actuation, isolation, holding, or replacement without rewiring the machine.
- Confirm handle or pedal return style
- Check normal state and flow direction
- Send label, port plate, and installed photo
Valve and flow tools
Check flow, Cv, velocity, and unit conversion before choosing valves.
Use these calculations when a pneumatic valve decision depends on flow capacity, pressure loss, port size, or catalog unit conversion.
