About the Airtac PHV Hand Valve Connector PHV12BD
The PHV12BD is a manual quarter-turn shut-off valve, not a speed controller: turn the cap with a finger and the air path through the Dia 12 tube closes completely, turn it back and it opens fully. This is the B version, a 2-port layout, so closing the valve traps air downstream instead of venting it to atmosphere - the line stays charged until you deliberately bleed it. The D suffix on the code means the body is supplied in black rather than the standard grey.
Every wetted part in the PHV family is specified without brass, which makes this valve a natural pick where copper or zinc contamination matters - plating lines, electronics assembly and similar processes. It is rated at 0-1.0 MPa working pressure and tolerates -750 mmHg vacuum, and because it is already copper-free as standard, AirTAC publishes no separate stainless variant for it.

Fitting & Sealing Notes
- check Cut the tube square and clean before pushing it home, or the seal will leak.
- check Push until it stops, then pull back to check the chuck has gripped.
- check To release, press the collet ring fully in and pull the tube out.
- check Threaded parts arrive with sealant on the thread; M5 sizes use a sealing gasket.
- check Match the tube OD exactly - a 6 mm fitting will not hold 1/4" tube.
Where the Airtac PHV Hand Valve Connector PHV12BD Is Used
Packaging machine jaw maintenance
Fit the PHV12BD in a 12mm air drop feeding the sealing jaws of a vertical form-fill-seal machine so a technician can isolate the drop during film or heater changes without shutting down the whole machine.
Plating line actuator isolation
The brass-free PHV12BD isolates the air feed to a lift or tilt cylinder above an electroplating bath, keeping copper and zinc out of a process chemistry where both metals cause contamination.
Test rig bench shut-off
On a pneumatic leak-test or fixture-proving bench with 12mm trunking, the 2-port black finger valve gives the operator a one-touch supply cut-off before swapping tooling plates or fittings.
Is the Airtac PHV Hand Valve Connector PHV12BD the Right Part?
Dia 12 is the largest bore in the PHV ladder, which runs Dia 6, 8, 10 and 12 only. If you are at the top of this size step there is no bigger finger valve to step up to; the next size down, the PHV10B, suits smaller tube runs where a little more flow restriction is acceptable. Choose the 12mm bore for main air drops feeding several actuators, where you want the shut-off itself to add as little resistance as possible. Pick the A version instead if you want the downstream side vented when the valve is closed - that is the safer choice where an operator will work on the actuator itself.
Remember this valve is for isolation only. It does not throttle, so stroke-speed control on the same circuit still needs a speed controller such as a PSL or PTL fitted at the cylinder port.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
Airtac PHV Hand Valve Connector PHV12BD FAQ
The PHV12BD is a 2-port finger shut-off valve for Dia 12mm soft nylon or polyurethane tubing, finished in black. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it withstands vacuum down to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The PHV family contains no brass, so the valve is copper-free as standard.
The A version is 3-port: when you close it, the downstream outlet vents to atmosphere, so trapped pressure cannot reach anyone working on the actuator. The B version (this SKU) is 2-port and simply blocks the flow, leaving air trapped downstream. Use the B type where you want to isolate a branch without dumping the rest of the circuit, and the A type wherever an operator services the downstream hardware.
