Brass Electronic Ball Valve

The Dynaquip Controls EYHG7AUE25H is a three-way ball valve with a brass body and nickel-chrome plated brass ball. It operates on 12V DC or 24V AC/DC supply and carries a 400 psi maximum operating pressure rating. An electric actuator rotates the ball 90 degrees in 6 seconds and includes a heater, position indicator and thermal overload protection. The fail-last design holds the last position on power loss.

Industrial fluid control automation

This valve suits process lines that need automated diverting or mixing with PTFE and FKM seals compatible with many media. The 300 psi maximum operating pressure differential and 100 psi steam rating cover typical hydronic and low-pressure steam circuits. Installations requiring a spring-return fail-safe position or faster cycle times should evaluate other actuator styles.

400 psi operating pressure headroom

The two-piece brass construction handles 400 psi non-shock cold working pressure with 300 psi allowable pressure drop across the ball. PTFE seats and FKM seals maintain sealing integrity through repeated 90-degree cycles at the rated differential. Steam service is limited to 100 psi, so higher-pressure steam systems exceed the valve's design envelope.

Questions about this item

What power supply does the 12V DC / 24V AC/DC actuator require?

The actuator runs on 12V DC or 24V AC/DC, so you must provide a compatible 12V or 24V power source and wiring to the actuator terminals.

Will the 1-1/2" FNPT brass valve body and 400 psi rating work with my existing Schedule 40 piping?

The two-piece brass body has 1-1/2" FNPT threads and a 400 psi maximum operating pressure; it will thread onto matching Schedule 40 fittings rated for at least that pressure.

How do I verify the valve cycles correctly after wiring it?

Apply power and watch the position indicator; the actuator should complete a 90-degree turn in about 6 seconds and the indicator will show the new port alignment.
