1-1/2″ FNPT Brass Pneumatic Ball Valve

The Dynaquip Controls PYHG7AUS054A is a pneumatically actuated three-way ball valve built for diverting or mixing flow in compressed-air and inert-gas piping. Its 1-1/2 inch FNPT connections suit industrial maintenance crews and OEM panel builders who need a compact L-port valve that mounts directly in threaded pipework.

400 psi CWP rating with 80 psi actuation

The brass body and nickel-chrome plated ball handle a cold working pressure of 400 psi, while the pneumatic actuator requires 80 psi pilot pressure and tolerates up to 120 psi inlet pressure. RTFE seats and PTFE/Viton body seals maintain seal integrity across a temperature range of -4 to 176 degrees F, so the valve performs reliably in chilled or moderately heated lines.

NEMA 4X brass construction for wash-down areas

The one-piece brass body meets NEMA 4X, allowing installation in wet or corrosive environments without additional enclosures. FNPT threads simplify assembly with standard pipe fittings, and the nickel-plated brass stem resists galling during frequent cycling, reducing downtime for seal replacement in high-cycle automation cells.

Questions about this item

Will the 1-1/2" FNPT threads on this Dynaquip PYHG7AUS054A valve match my existing brass piping?

The valve uses 1-1/2 inch FNPT connections, a standard tapered pipe thread that mates with matching male NPT fittings on your current brass pipework.

How can I verify the pneumatic actuator is functioning correctly after installation?

Apply 80 psi control pressure and confirm the ball rotates smoothly through the L-port path; the valve is rated for 120 psi maximum inlet pressure and 400 psi CWP.

Does the PYHG7AUS054A come with the pneumatic actuator mounted, or must I order it separately?

The supplied unit is a complete pneumatically actuated ball valve with the actuator already mounted on the 1-piece brass body; no separate actuator purchase is required.
