Dynaquip Controls PYHG4AUUSR0209A 3/4" FNPT Brass 3-Way Pneumatic Ball Valve
A pneumatically actuated three-way brass ball valve with a 115V AC pilot solenoid and a fail-closed safety position rated for 300 psi operating pressure
- Pneumatically actuated for automated flow control
- Three-way L-pattern directs media between ports
- Brass body handles 300 psi operating pressure
- 115 V AC pilot solenoid enables electric actuation
- Fail-closed spring return adds safety on air loss
3/4" FNPT Brass 3-Way Valve
This pneumatically actuated three-way ball valve controls compressed-air flow in automated systems. The brass body with standard port suits general-purpose pneumatic circuits where a compact L-pattern diverts or shuts off supply.
Verify pressure and voltage before ordering
Your air supply must not exceed 300 psi operating pressure or 100 psi steam pressure. The included pilot solenoid requires 115 V AC power, and the actuator is air-to-spring with a fail-closed position, so confirm your control voltage and available instrument air.
Solenoid and fail-safe change installation
The factory-fitted 115 V AC pilot solenoid removes the need to source a separate coil, while the fail-closed spring return moves the valve to a known safe state on air or power loss, simplifying safety interlock wiring.

Questions about this item
What is included with the valve and what must be purchased separately?
The valve body, pneumatic actuator, and a 115V AC pilot solenoid are included. Compressed-air supply tubing, fittings, and any required electrical wiring are not included and must be sourced separately.
How do I choose between the available pressure ratings for this valve?
The valve is rated for 300 psi maximum operating pressure and 300 psi maximum operating pressure differential; for steam service the limit is 100 psi. Select the rating that matches the highest pressure your system will see.
What does the 300 psi operating-pressure figure mean once the valve is installed?
It means the valve can withstand up to 300 psi in the line and a 300 psi pressure drop across the ball without leaking or structural failure during normal pneumatic operation.
