Solenoid Valve Body 1/4 in Stainless Steel

The Dayton 4A691 is a two-way, two-position solenoid valve body constructed from stainless steel. It features a normally closed starting configuration with a 1/16 in orifice diameter and a coefficient of volume (Cv) of .05. This component is designed for controlling the flow of air, inert gas, or water in plumbing and fluid handling systems.

Check Pipe Size Pressure and Coil Requirements

Verify that your piping uses a 1/4 in nominal pipe size to match the valve body connections. Ensure your system operating pressure differential does not exceed 500 psi for air, inert gas, or water applications. Confirm the fluid temperature stays below 180 degrees F and note that this valve body ships less coil, so a compatible coil must be sourced separately for operation.

Suits Corrosive Indoor or Outdoor Fluid Control

This valve body suits installers needing a stainless steel solution for corrosive environments rated for indoor or outdoor use. It is not for buyers who require an integrated coil assembly or a larger orifice size for higher flow rates. It also does not suit applications exceeding the 500 psi maximum pressure differential or 180 degrees F temperature limit.

Questions about this item

Does the Dayton 4A691 solenoid valve body come with a coil, or must I buy one separately?

The valve body is sold less coil, so a compatible coil must be purchased separately to operate the valve.

Which pipe size and orifice combination matches the 1/4 in nominal pipe size listed for this valve?

This model has a 1/4 in nominal pipe size and a 1/16 in orifice diameter with a Cv of 0.05.

What maximum pressure can the 4A691 handle when controlling water in a live system?

The valve is rated for a maximum operating pressure differential of 500 psi for water service.
