Propellant, 50 to 100lbs

Description

Part number 15027 is a dual seat propellant control valve qualified for thrusts from 50 to 100 LBf. The valve was developed for the Space Station Freedom Long Life Monopropellant Thrusters and demonstrated a throughput of over 6400 pounds of hydrazine over 100,000 valve cycles.

Part number 15027-11 is a single seat propellant valve derived from the 15027 design. Derivative designs will fly on VEGA, Mars Science Laboratory and other U.S. Government Programs. These designs use ValveTech’s patented Center Guide Technology for high cycle life and reliability. They are all welded stainless steel construction and use an AF-E-411 puck in an annular type seat for seat sealing.
