The HDEV 1.2 valve can be used with direct injection systems and high pressure manifold injection systems. It has a small size and weight while allowing flexibility to define spray and jet positions, flow rates, and penetration. Asymmetric sprays are also possible. The valve operates at pressures up to 200 bar with a flow rate of 30 ccm/sec at 100 bar and has electrical resistance of 0.9 ohms at 90 volts and 20 amps of peak current. Example jet configurations include circular, dual circular, and flat patterns.

1. HPI Valve HDEV 1.2
The HDEV 1.2 can be used in combination
with direct injection systems as well as in
high pressure manifold injection systems.
Its most remarkable features are the small
size and weight and the freedom in
defining both – spray and jet. Every jet is
free definable in terms of position, flow
rate and penetration. Moreover,
asymmetric sprays are possible.
