PHV inline finger valves provide A three-way shutoff with outlet venting or B two-way shutoff for6/8/10/12 mm tube. Match the body flow arrow, A/B knob marking and downstream pressure-release requirement; send code or circuit photo for quotation.
Know your model? Send it with the quantity for a quote. Not sure? Start with a photo, label or description. We help identify the model and clarify availability and lead time. Mixed parts lists are welcome too.
Choose a type; send a model or photo if unsure.
PHV-A
Three-way: downstream outlet vents when closed
PHV-B
Two-way: flow shutoff without published automatic outlet vent
Send the model, quantity and destination. For multiple items, attach a parts list or BOM.
Match a PHV Finger Valve Code
AirTAC PHV specification
Helpful for Model Matching:
| Valve identity | PHV manually operated inline finger valve with tube push-in ends. A is three-way, B two-way. It is not an electric solenoid, speed controller, pressure regulator or certified safety valve. |
| A versus B air circuit | A three-way connects supply to outlet when open and releases outlet pressure through exhaust when closed. B two-way shuts off flow without a published automatic outlet-exhaust function. Downstream trapped pressure, check valves and stored energy require actual circuit confirmation; no universal complete depressurization guarantee. |
| Flow direction and knob state | Match inlet/outlet with arrow on body. Open: knob arrow aligned with body arrow. Closed: knob arrow at90° to body arrow. Source states uni-direction character; do not assume reverse installation, bidirectional venting or interchangeable P/A ends. |
| Tube and code matrix | Tube OD6/8/10/12 mm, A three-way or B two-way, blank grey or D black. Both release collar and body follow color. Knob has A/B identifier. No pipe-thread, G/NPT, coil voltage or throttling-setting code field. |
| Pressure and temperature | Operating0–1.0 MPa; proof1.5 MPa; ambient/fluid−20 to+70°C; vacuum−750 mmHg. Soft nylon or polyurethane tube. Proof pressure is not continuous working pressure; confirm actual tube condition and exhaust duty. |
| Materials and application boundary | Catalogue says no brass/copper body; published components include POM, PBT plastic body, aluminium alloy, stainless pin/spring and NBR seals. Copper-free claim is not food/medical/oxygen/chemical compatibility certification. No flow coefficient, lifetime cycles or certified isolation rating supplied. |
| Mounting dimensions | A overall dimension for6/8/10/12 =51.5/58.5/66/71 mm; B17/18/21/22 mm; C40.5/42.5/42/46 mm; weight14.3/17.5/25.1/31.4 g. A/B valve functions share published external dimensions. Use actual collar access, knob swing and mounting-hole drawing; dimensional match alone does not prove circuit compatibility. |
| Inquiry inputs | Send full code or valve photo, tube OD/material, A/B knob mark, body flow arrow, inlet/outlet circuit and downstream venting requirement, color, pressure/temperature, clearance, quantity and destination. |

PHV inline finger valves provide A three-way shutoff with outlet venting or B two-way shutoff for6/8/10/12 mm tube. Match the body flow arrow, A/B knob marking and downstream pressure-release requirement; send code or circuit photo for quotation.
The source explicitly publishes outlet pressure release for A three-way, not B two-way. Correct flow direction and the real downstream circuit must be confirmed; trapped pressure behind other valves may remain. This source gives no certified safety-isolation guarantee.
