Product Overview


The latching valve works with a short pulse of energy (50 ms) that will open the valve and keep it open until the polarity is reversed, closing the valve.

  • Valve opens with quick positive pulse (red wire to "+" & black wire to "-")
  • Valve closes with quick reverse pulse (red wire to "-" & black wire to "+")
  • Valve stays in position with no additional power being applied

Model FCD-138D is a two-way magnetically latching valve also known as a pulse valve. This means that there are two ports in which media flows, the valve will open when a short pulse is applied, allow media to pass through and stay open until a reverse pulse is applied. This valve is ideal for battery operated systems because it dosen't require constant power. 

The port size is 1/2” inch, non-tapered male threaded (usually found in faucets). It can withstand pressure up to 115 psi (8 bar) and temperatures as low as 32 F and as high as 125 F. The seal material is EPDM Rubber. This valve is capable of flowing 6.5 Gallons per minute at the max rated PSI.

This specific plastic valve has a 12 Volt DC coil with a voltage range that is -+ 10. Its response time is very low; in fact, it acts in less than one second, making it a great choice for all types of applications.

The coil head can easily be connected with your own terminal connectors or directly soldered. Included is a Built-in filter screen to prevent debris from entering the valve body.
