  • 115 V AC pilot solenoid included

1/4" Pneumatic Ball Valve

The Dynaquip Controls PHS21AJS012A is a pneumatically actuated two-way ball valve with a nominal size of 1/4 in. It features a 316 stainless steel ball and body for corrosion resistance in demanding fluid control applications. A 115V AC pilot solenoid is included for direct electrical control of the air supply. The straight body style uses FNPT connections for inline piping.

Suits automated shut-off needs

This valve suits systems requiring automated on-off control where a fail-safe closed position is mandatory. The air-to-spring operation ensures the valve returns to its normally closed state upon loss of air pressure or power. Buyers who need a valve that fails open or stays in its last position on failure should look at a different actuator design. It is not intended for manual-only operation.

Sustained pressure performance

Under continuous operation the valve withstands a maximum operating pressure of 1,000 psi and a maximum steam pressure of 150 psi. The full port design maintains flow capacity without restriction during extended duty cycles. Stainless steel construction resists degradation from prolonged exposure to compatible media. The fail-closed spring returns reliably after repeated actuation cycles.

Questions about this item

What compressed-air supply pressure is required to operate the 115V AC pilot solenoid on this valve?

The pilot solenoid runs on 115V AC power; the valve itself is rated for up to 1,000 psi operating pressure and 150 psi steam pressure.

Can the 316 stainless steel ball and full-port design handle the same 1,000 psi rating as my existing 1/4" FNPT piping?

Yes, the valve body and ball are both 316 stainless steel with a full-port design rated for 1,000 psi maximum operating pressure.

How can I confirm the valve returns to its normally closed position after the air signal is removed?

The fail-safe spring-return actuator forces the valve to the closed position when pilot air is exhausted, providing a visible stem indication.
