The BK2 Valve is a reliable valve featuring a push button auto-expulsion feature that allows amputees to utilize suction suspension instead of the old standard locking suspension. This valve is designed for BK users with a transtibial suction socket who want auto-expulsion with a push button release.


The BK2 Valve is one of ESP’s simpler versions for a BK suspension system. This product is designed for below-the-knee patients that want auto-expulsion WITH an easy-to-use push button.  The BK2 Valve with push button is our more popular version of this valve, but patients who prefer a valve without a button can use our BK Valve instead.

The BK2 Valve allows wearers to utilize suction suspension in their prosthesis instead of the old standard locking suspension.

Clinicians can utilize the BK2 Valve with our BK/BK2 Threaded Housing (PA0222) to give the user an inner flexible socket.

Releases air at ½ PSI without adjustments. Designed with a low profile: ⅞” diameter.
