General Information
The Ceram™ 4-way pneumatic directional control valve uses sliding ceramic plates to form a nearly perfect, indestructible seal. The plates wipe themselves clean, shrugging off ingested dirt that destroys ordinary valves. The valve is pre-lubed with grease. Its unique ceramic plate wiping action prevents wear even without line lubrication. An extensive field service testing program verifies an anticipated life of 30 million cycles under adverse conditions. The valve has an ISO 5599/1 mounting dimension so its completely interchangeable with other ISO valves.

The Ceram™ valve operates with 50 or 60 Hz service, using continuous duty plug-in solenoids with DIN 43 650 connectors and meets NEMA 4 electrical specifications for wash down applications. The valve is available with single or double air pilots operators.

There are four basic valve sizes, all meeting ISO specifications. Subplates and manifold available for 1/4˝ through 1˝ N.P.T. piping. The manifolds can be either end or bottom ported and are fastened together in stack form with a unique set-screw. No special tie rods required.

Four methods of operation. Single or double air piloted solenoids and single or double air pilots. Solenoids can be supplied with either internal or external pilot supply and single solenoids can be either metal spring or air spring return. Air pilots receive pressure from small ports in the subplate or manifolds.

For special requirements of speed or force, the Ceram™ valve can provide sandwiched flow and pressure regulator controls on sizes I and II. Sizes I and II manifolds can be connected together in one stack through the use of Jumper Plates.

The Ceram™ valve has a lasting construction with corrosion resistant materials, and finishes.
