fcv001
Product Overview:
A flow control valve designed for the control of propellant in storable, liquid propulsion systems.
The design comprises of two essentially identical, solenoid operated, normally closed, poppet type valves mounted coaxially in series. Each of these solenoid valves comprises a coil, fixed pole and a suspended moving/armature, to which is attached a sealing pin, the valve seat is located in the valve outlet. The poppet/seat interface has been designed to
minimise flow discontinuities and therefore reduce susceptibility to contamination induced failures.
This valve is an adaptation of the successful SV06/SV14 series of valves modified for use with hydrazine in monopropellant propulsion systems by the introduction of a PTFE seal in a vacuum brazed and EB welded body.
