ACTIVITY CODE | 4B.134
1/4″ Normally Closed SMAV Single Use Valve

Objectives

The activity covers the final development steps and the qualification of a normally closed valve for use with Monomethyl hydrazine, dinitrogen tetroxide and inert gases. The valve is equipped with a shape memory alloy actuator that is triggered by electrical heating.

Challenges

A key challenge was a robust thermal design that allows activation of the valve in a broad environmental temperature range.

Plan

The following milestones are covered in the activity: CDR, QTRR, QTRB and Qualification Review/Final Review.

Current Status

Project is finalized. Next step is on orbit validation.
