DirectAir 2 3-Way Manual Valve
The Parker 414211000 is a 3-way, 2-position manual air control valve built for compressed-air systems. Its aluminum body measures five inches long and fits a 1/8 inch NPT port. The valve operates at up to 150 psi and handles temperatures from 32 to 175 degrees F. It suits technicians who need direct, spring-return actuation on a compact footprint.
Replaces 2-way or leaking 3-way units
Swapping a simple on-off valve for this 3-way model adds a closed-center position that holds pressure when the lever is released. The upgrade is worth it when a circuit must trap air between cycles or when an older valve passes .2 cfm at rest. The roller-and-spring return ensures consistent reset without external pilots.
Check port thread and pressure rating
Verify that the existing line uses 1/8 inch NPT threads and that system pressure never exceeds 150 psi. Confirm the 32-to-175-degree-F range covers the coldest and hottest conditions at the install point. Ensure the five-inch length and five-eighths-inch width clear surrounding fittings and brackets.

Questions about this item
What thread size does the Parker 414211000 valve need for mounting?
The valve uses 1/8 inch NPT threads on its ports, so it fits directly into matching 1/8 NPT fittings or manifolds without adapters.
How is the Parker 414211000 installed, and what step is often missed?
Thread the valve into a 1/8 NPT port using pipe sealant on the male threads only; the common mistake is over-tightening the aluminum body, which can crack the housing.
What maintenance will the Parker 414211000 need over time?
Inspect the roller actuator and spring return for wear or debris; replace the valve if the three-way switching becomes sticky or if air leaks appear at the 150 psi pressure rating limit.
