NEX-Valve - First Sensor

NEX-Valve
8 mm non elastomeric switching solenoid valves
FEATURES
· 2-way, 2 position valve, normally closed,
bidirectional flow
· Non-elastomeric design allows for high
media compatibility
· Compact size, only 8 mm in width
· Power consumption as low as 0.5 W,
PWM and pulse hold circuit compatible
· Fulfils leakage specification for over
1 million cycles
· Ensures high reliability with its single piece
body design
· Barbed pressure ports allow for direct
tubing or manifold assemblies
· RoHS compliant

Notes:
1. The CV value is the volume flow in US gallons/min under specific flow conditions and describes the relative flow capacity of a
valve. The equivalent european measure is the kV value expressed in m3/h (kV = 0.86 CV).
2. Proof pressure is 200 psig
