DASH 1 Valves
The DASH 1 valve family is based on a direct solenoid poppet that can be either a three way (3/2) or a two way (2/2) valve. The DASH 1 is a precision combination of miniature size, fast response, high flow, low power, and long life.
There are several valve versions in the DASH 1 family. Cataloged models include: ports in body, manifold mount, adapter plate, PC board mount, and 1/8 pipe-stud output.
DASH 2 Valves
There are no moving seals in the DASH 2 valve! The DASH 2 is a metal to metal lapped spool valve. Traditional metal to metal valves can be unforgiving and require extremely fine filtration. Dynamco’s design of using dissimilar metals of different hardnesses eliminates the need.
Dynamco controls the clearances between the body and spool by individually match fitting each spool and body to achieve a proper floating air bearing. The clearance has a narrow range that every valve must achieve. The thermal expansion coefficients of the body and spool are the same so the clearance stays the same over a wide range of temperatures.
DASH 3 Valves
There are no moving seals in the DASH 3 valve! The DASH 3 is a metal to metal lapped spool valve. Traditional metal to metal valves can be unforgiving and require extremely fine filtration. Dynamco’s design of using dissimilar metals of different hardnesses eliminates the need.

Bleed Feed Valves
A Bleed/Feed valve acts as a 3-way, 3-position, closed center control valve, with two solenoid operators. As you can see from the pictures to the right, the Bleed/Feed valve is essentially two DASH 1 valves that have been mounted together with special porting, depending on customer requirements.
