Quick answer: These are Philips Respironics exhalation valves for active dual limb ventilator circuits, supplied as a 10-pack (SKU 1139436). In an active circuit, the exhalation valve is what controls the release of exhaled gas — the ventilator opens and closes it in time with the breath cycle. These are single-patient, disposable consumables, replaced per the manufacturer's instructions and your clinical protocol.
What's included
- 10 × active dual limb exhalation valves (SKU 1139436)
Breathing circuit, ventilator, and patient interface not included. Confirm compatible ventilator models against your packaging.
About these valves
Ventilator circuits fall into two broad types. In a passive circuit, exhaled gas escapes continuously through a fixed leak port. In an active circuit, a valve does the job instead — the ventilator actively opens it to let the patient exhale and closes it during inspiration, which gives more precise control of delivered volume and pressure.
In an active dual limb setup, exhaled gas returns to the device through a separate expiratory limb, and this valve sits in that path. Because it's a moving component exposed to warm, humidified exhaled gas, it's a wear item — the diaphragm can stiffen, deform, or accumulate moisture and secretions over time, which affects how cleanly it seals and cycles.
A 10-pack is the practical fulfilment size for clinics, home-care agencies, and anyone changing valves on a routine schedule.

Use & safety notes
Fit the valve exactly as specified in your circuit setup and the ventilator's clinical documentation, and confirm correct orientation — a valve fitted the wrong way round will not cycle correctly. Many ventilators require a circuit test or calibration after a circuit or valve change; run it before returning the patient to therapy. Replace the valve per the manufacturer's instructions, and sooner if it becomes soiled, wet, deformed, or if you observe changes in exhalation or unexpected alarms. Follow your clinical team's protocol at all times.
Frequently asked questions
How many valves are in the pack? Ten.
What does an exhalation valve do? In an active circuit, the ventilator opens and closes the valve in time with the breath cycle — controlling the release of exhaled gas rather than relying on a continuous fixed leak.
What's the difference between active and passive circuits? A passive circuit vents exhaled gas continuously through a fixed leak port; an active circuit uses a valve that the ventilator controls, giving more precise delivery.
Which ventilators do these fit? Please confirm against the packaging, or contact us at (718) 735-3400 with your ventilator model and we'll check before you order.
How often should they be replaced? Per the manufacturer's instructions and your clinical protocol — and sooner if soiled, wet, or deformed.
Are they reusable? No — these are single-patient-use consumables.
Do I need a prescription? Yes — ventilator components are used under clinical direction. Confirm your prescribed setup with your provider.
Can I get them delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
For use under clinical direction. Follow the manufacturer's instructions for use and replacement, the ventilator's clinical documentation, and your provider's or facility's protocol — including any required circuit test after a valve change.
