The Chemical Thruster Valve consists of a pair of identical valve cores welded together. The inlet and outlet fittings are different which creates the upstream and downstream valve. Each valve stage is a solenoid operated flow control valve with a single seat, single coil, normally closed with non-sliding fit configuration.

The design of the seal/seat interface ensures minimal flow discontinuities, therefore reducing susceptibility to contamination induced failures and minimising pressure losses.

Each valve is opened independently by energising each coil; the resulting force generated by the induced magnetic flux causing the armature to move towards the ‘fixed pole’, and in doing so lifts the seal from its seat.

The valve is a fully welded structure, ensuring the external leak rate is zero. The inlet incorporates a 25µm particle filter, which is welded in place. The inlet to the valve can be supplied with welded or threaded connections, using straight inline and right angled connections. The outlet flange incorporates the interface with the thruster or other equipment. This is typically a bolted flange
