1" FNPT Brass Pneumatic Ball Valve

This new Dynaquip Controls valve uses a brass body with a three-way L-port design for diverting or mixing flow in bathware plumbing. It connects via 1" FNPT threads and operates with pneumatic actuation at a required pressure of 80 psi. The 1-piece body construction suits installations where a compact, integrated valve is preferred.

Thermals noise and power draw

The valve handles fluid temperatures from -4 to 176 degrees Fahrenheit and a maximum inlet pressure of 120 psi with a 400 psi CWP rating. Pneumatic operation eliminates electrical power draw and motor noise during normal cycling. Internal seals use PTFE and Viton materials compatible with the stated temperature and pressure range.

NEMA 4X rated actuator

The actuator meets NEMA 4X standards for corrosion resistance and wash-down environments common in bathware settings. Nickel-plated brass stem and chrome-plated brass ball components extend service life in humid conditions. RTFE seats provide chemical compatibility without requiring additional lubrication or maintenance kits.

Questions about this item

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

Thread the valve onto 1" FNPT piping using compatible sealant, then connect the pneumatic actuator to a clean, dry 80 psi air supply; the step often missed is verifying the actuator receives the required 80 psi before pressurising the line.

What maintenance or replacement will the valve need over time?

Plan to inspect and potentially replace the RTFE seats, PTFE/Viton body seals, and nickel-plated brass stem packing as they wear; the Ni-Chrome plated brass ball and brass body typically last longer but should be checked for corrosion during scheduled shutdowns.

What limit appears first during sustained operation of the valve?

The 400 psi CWP pressure rating is the primary limit; sustained inlet pressure must not exceed 120 psi and the temperature must stay within -4 to 176 °F, otherwise the seat and seal materials will degrade first.
