Industrial Flow Control

The Banjo V400 is a four-inch standard port ball valve built for inline shut-off in fluid-handling systems. Its polypropylene body is reinforced with fiberglass for structural strength, while FKM seals and PTFE seats provide chemical compatibility across a range of media. The valve is designed for new installations or replacements where a quarter-turn, full-bore path is required.

Upgrade from Leaking or Seized Units

This valve replaces older metal or un-reinforced plastic valves that corrode, bind or leak at the stem. The diamond-turned ball ensures spherically precise contact with the seats, and the self-lubricating PTFE bushings eliminate the stick-slip common on dry-stem designs. The jump is worth it when maintenance intervals must be extended and downtime reduced.

100 psi Rated Service

The assembly handles a maximum operating pressure of 100 psi in water, fertilizer or chemical transfer lines. Stainless steel bolts maintain joint integrity under vibration and thermal cycling. Headroom diminishes above the rated pressure or in applications requiring full-port flow coefficients; the standard port design introduces some restriction at peak demand.

Questions about this item

What size and thread type does the V400 valve use for inline installation?

The valve is a 4" standard-port model with FNPT threads for direct inline connection.

Which step is most often missed when installing the stainless-steel bolts on this valve?

Torque the stainless-steel bolts evenly in a cross pattern so the fiberglass-reinforced polypropylene body seats without stress.

How often should the FKM seals and PTFE seats be inspected or replaced on the V400?

Inspect the FKM seals and PTFE seats annually; replace them if leakage appears or handle torque increases noticeably.
