Small stainless steel solenoid valve body with 1/8 inch ports

Dayton

Dayton 4A688 1/8 in Stainless Steel Solenoid Valve Less Coil

SKU CH-GTA2-2HT22 MPN 4A688

Stainless steel 2-way solenoid valve body, normally closed, 1/8 in pipe, 0.12 Cv, up to 500 psi air or water, 180 °F max fluid temperature, indoor/outdoor corrosive rating

  • Product typeDrain Components
  • Stainless steel body resists corrosion in harsh environments
  • Normally closed design keeps flow sealed until energised
  • 1/8 in port with 1/16 in orifice suits compact piping
  • Handles up to 500 psi air, water or inert gas
  • Operates reliably up to 180 °F fluid temperature

1/8 in Stainless Solenoid Body

The Dayton 4A688 is a two-way, normally closed solenoid valve body made from stainless steel. It is designed for fluid control in plumbing and industrial systems where corrosion resistance is required. The 1/8 inch nominal pipe size suits compact piping layouts. This component is sold without a coil, so a compatible actuator must be sourced separately.

500 psi Pressure Limit

The valve handles a maximum operating pressure differential of 500 psi for air, inert gas, and water. Minimum differential is 0 psi, allowing operation in low-pressure or gravity-fed circuits. The orifice diameter of 1/16 inch and Cv of .12 restrict flow to small volumes. Fluid temperature must not exceed 180 degrees F.

Low-Flow Fluid Control

With a Cv of .12, the valve comfortably handles metering, sampling, and pilot-line duties. It runs out of capacity quickly in high-volume fill or drain applications. The stainless body suits corrosive, indoor, and outdoor environments. Buyers needing larger flow paths or integrated coils should select a different valve body.

Questions about this item

Should I pick the 1/8 in or 1/16 in size for my line?

The valve body has a 1/8 in nominal pipe size; the 1/16 in figure is the internal orifice diameter.

What flow can I expect from the 0.12 Cv rating?

A Cv of 0.12 means roughly 0.12 US gallons per minute of water with a 1 psi pressure drop.

Will the 500 psi air rating hold on my compressor line?

Yes, the maximum operating pressure differential for air or inert gas is 500 psi.
