product overview
Marotta's miniature 2-Way, 2-Position in-line valves are well designed specifically for electric propulsion applications such as:
 
- Inert Gas, Low Flow Isolation
- Low Power & Mass Systems

OPERATING DESCRIPTION

Weight and envelope of the SPV187 series valves are minimized by utilizing a coaxial design.  The valve plunger and poppet are combined into a single moving element.

When the valve is energize the plunger/poppet is lifted off the seat, allowing flow through the central flow ports to the outlet with minimal pressure drop.

Numerous variations are available for customer specific porting, power and fluid requirements.
