Pneumatic Master Valve 310 Series

The CKD 4KA310-M1LS is a pneumatic master valve designed for electricians who need reliable air-flow control in test and service environments. It arrives new in a single-pack box with a red finish for quick visual identification on the job site.

Replaces Worn Directional Valves

Swap this unit in when an existing master valve leaks, sticks or fails to shift cleanly under pressure. The upgrade is worth it when downtime from intermittent actuation costs more than a direct replacement that restores consistent pilot-air delivery.

Fits Standard Pneumatic Circuits

The valve threads into common port sizes used in electrician test rigs, letting you restore circuit integrity without re-plumbing. Its compact body frees manifold space for additional stations while the three-year parts coverage supports long-term maintenance planning.

Questions about this item

What port size does the 4KA310-M1LS master valve require for pneumatic connection?

The valve body uses standard pneumatic port threads compatible with common airline fittings; match the thread size to your existing tubing or manifold specification.

How is the 4KA310-M1LS valve mounted and which step is most often missed?

Mount the valve using the integrated body holes onto a flat panel or manifold block; the step most often missed is applying thread sealant only to the male fitting threads, not the valve ports themselves.

Which wearable components on the 4KA310-M1LS will need replacement over time?

Internal seals and the pilot piston assembly are the primary wear items; plan to inspect and replace the seal kit after extended cycling or if leakage appears at the exhaust port.
