Stainless steel pneumatic ball valve with 115V AC pilot solenoid

Dynaquip Controls

Dynaquip Controls PHS24AJS034A 3/4" FNPT Stainless Steel Pneumatic Ball Trap

SKU CH-9EHF-X5D3D MPN PHS24AJS034A

A pneumatically actuated two-way ball valve with a 316 stainless steel body and ball, full-port design, air-to-spring operation, normally closed fail-safe position, 115V AC pilot solenoid.

  • Product typeDrain Components
  • Pneumatically actuated for automated flow control
  • 316 stainless steel ball resists corrosion
  • Full-port design maintains unrestricted flow
  • 115 V AC pilot solenoid enables direct electrical control
  • Normally closed fail-safe position closes on air loss

Pneumatic Ball Valve 3/4" FNPT

The Dynaquip Controls PHS24AJS034A is a pneumatically actuated two-way ball valve with a 3/4 inch FNPT connection. It features a 316 stainless steel ball and body for corrosion resistance. The valve operates on an air-to-spring mechanism with a normally closed deactivated state. A 115V AC pilot solenoid is included for control.

Suited for Automated Shut-Off Systems

This valve suits process lines that require fail-closed safety action and full-port flow capacity. The 1,000 psi operating pressure rating supports high-pressure air, water, or inert gas service. Buyers needing electric actuation, a normally open fail position, or a different voltage solenoid should look at other models. The straight body style limits use in angled piping layouts.

Pressure Headroom and Flow Capacity

The full-port design provides unrestricted flow equivalent to the 3/4 inch pipe size. The valve handles up to 1,000 psi operating pressure and 150 psi steam pressure with the stainless steel construction. Headroom exists for pressure spikes below the maximum operating limit. The fail-closed spring requires sufficient supply pressure to overcome the spring force and hold the valve open.

Questions about this item

Will the 115V AC pilot solenoid operate from my existing 115V AC control circuit?

Yes, the included pilot solenoid is rated for 115V AC and will operate directly from a standard 115V AC control circuit.

How does the fail-closed design affect my existing pneumatic system during air supply loss?

The valve returns to the normally closed position automatically when pneumatic pressure is lost, isolating the line as a fail-safe measure.

What visual indication confirms the valve has actuated correctly after installation?

Apply 115V AC to the solenoid and supply pneumatic pressure; the valve should open, and removing the electrical signal should cause it to spring-return to the closed position.
