The Valve consists of a single valve cores brazed together. The 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.

The valve is opened independently by energising the 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 an externally fully welded structure, ensuring the external leak rate is zero. The inlet incorporates a 25µm particle filter, which is swaged securely in place. The inlet to the valve can be supplied with welded or threaded connections, using straight inline and right angled connections. The outlet tube can be similarly customised to suit customer requirements.
