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.

Scenario 01

Trigger an air signal from machine movement.

Roller or plunger valves can detect a moving machine element without electrical wiring.

Recommended option

Cam and roller limit signals

Mechanical valves generate an air signal when a slide, cam, fixture plate, or moving machine part reaches a defined position.

  • Review function, size, pressure, mounting, and inquiry data for Mechanical Button Control Valves.
  • Confirm contact direction
  • Check return style

Fixture presence checks

Plunger and roller valves can confirm a part, nest, or slide position before allowing the next pneumatic motion in a simple air-logic sequence.

  • Review contact force
  • Protect the actuator head
  • Keep tubing clear of movement

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.

Category FAQ

Common questions before sending an inquiry.

01Mechanical Button Control ValvesWhat is the difference between a mechanical valve and a manual valve?

A manual valve is operated intentionally by a person. A mechanical valve is usually triggered by machine contact, a cam, roller, plunger, or push mechanism.

02Mechanical Button Control ValvesWhat photos help identify a mechanical valve?

Send the label, actuator head, port side, mounting face, and full installed position so Bepto Pneumatic can compare the correct style.
