EV EXV (Electric Vehicle Electronic Expansion Valves)


To date, Schrader Pacific has prototyped EXVs for testing and evaluation by tier 1s. Note two different flow characteristics are available (below).

Schrader Pacific will partner with component and/or module suppliers of EXVs to tier 1’s under a confidentiality agreement. Please contact a sales representative to pursue.

Check Valves

Schrader Pacific engineers and manufactures check valves for many applications. Contract with us to develop/manufacture check valves for heat pump circuits in electric vehicles.

Shut-off Valves

Schrader Pacific can leverage experience with a wide range of valve designs to aid in the development of shut-off valves.

The charts above show typical pulse/flow characteristics of 2.6 and 9.0 mm orifice EXV.

Below, a typical system in which EXVs will routinely operate. Schrader Pacific can be contracted under a confidentiality agreement to partner in developing a valve to meet your specific needs.
