Stacking Manifold Example
Bolt-Together Subplates

For 3/8" Subplate-Type Valves - Body style 3P

These are individual subplates which can be bolted together to make a mounting surface (or manifold) for any number of 3/8" individual subplate mounting valves. Inlet pressure and exhaust connections are made to port holes on the side or bottom of end plates and manifolded through to all subplates. Cylinder and pilot ports come out the bottom of each subplate. Note: On long stacks, inlet and exhaust lines can be connected to both ends of stack to reduce internal flow resistance.

How to Order Stacking Manifold Valves

Individual parts can be ordered for user assembly. To improve stack assembly, when facing the standard actuator side of stack, specify blind (SMBE-3), 1/2" NPTF side ported (SMSC-4) or 1/2" NPTF bottom ported (SMBC-4) end plate. A SMOS spacer is required between the end plate and the first manifold. Then assembly manifold sections depending upon port size required. Then conclude with either a blind or ported end plate.

Stacking Manifold Assembly

The subplates are assembled using standard 5/16"-18 x 1-1/4" socket head cap screws, lock washers and nuts. Each SM2 or SM3 manifold includes hardware and seals for mounting manifolds together. Mounting hardware for assembling each subplate valve to the manifold is included with each subplate valve. If replacement O-Rings are required, you can use standard 5/8" I.D. x 13/16" O.D. Buna-N, 70 Durometer, O-Rings between subplates, spacer plates or end plates. These O-Rings can be ordered from AAA Products as part number V-110.
