Compact stainless steel pneumatic ball valve with silver actuator and solenoid coil

Dynaquip Controls

Dynaquip Controls PVS21AJS024A 1/4" 316 Stainless Steel Pneumatic Ball Valve Trap

SKU CH-X6FY-A0NG0 MPN PVS21AJS024A

A pneumatically actuated 316 stainless steel ball valve with 115 V AC pilot solenoid, full-port design and 1,000 psi operating pressure

  • TypeDrain Components
  • Pneumatically actuated for automated flow control
  • 316 stainless steel body resists corrosion
  • Full-port design maintains unrestricted flow
  • Normally closed with fail-safe spring return
  • 115V AC pilot solenoid included for operation

Application and Sizing

The pneumatically actuated two-way ball valve suits process lines that require a normally closed, fail-closed action with a 1/4 inch nominal bore. It is built for air, water, oil or inert gas service where a 316 stainless steel body and ball resist corrosion. Buyers who need a larger port, a different voltage pilot, a normally open fail mode or a manual override should select another model. The full-port design does not reduce flow compared with the pipe size.

Critical Specification

The maximum operating pressure of 1,000 psi and the 115V AC pilot solenoid voltage are the decisive figures. If your system pressure exceeds 1,000 psi or the available control voltage differs from 115V AC, this valve will not function safely. The 150 psi steam limit also governs suitability for steam applications.

Questions about this item

How do I install the 1/4" FNPT pneumatic ball valve and what step is often missed?

Thread the 1/4" FNPT connections into the pipeline using compatible sealant, then wire the 115V AC pilot solenoid; the step often missed is verifying the air-to-spring actuator receives clean, dry supply air at the correct pressure before cycling.

What maintenance or replacement will the 316 stainless steel ball valve need later?

Inspect the 316 stainless steel ball and seals periodically for wear; replace the pilot solenoid coil if actuation becomes unreliable, and rebuild or replace the valve assembly if leakage appears at the full-port ball seat.

What limit appears first when the valve runs continuously at 1,000 psi operating pressure?

The 150 psi steam pressure rating is the first limit reached under sustained high-temperature steam service, while the 1,000 psi operating pressure governs general pneumatic use.
