Spacer kits can be used to raise the HDBH system higher above the manifold surface
in order to avoid interference with other devices on the manifold. Kits are either 0.75”
or 1.75” tall. Combine kits as necessary to achieve the desired spacing.

In-line Mounting Kit
Kit Number
2790B77
In applications where installation on a manifold is not practical, the in-line mounting kit can be used
to facilitate installation in-line between a directional valve and actuator (typically a cylinder). The
2790B77 kit provides 2 mounting plates with multiple SAE 06 ports for the A, B, and T ports in order
to provide for flexibility in piping. At least one of the T ports must be piped back to the tank. Through
holes (0.422” dia.) for mounting the assembly are included in the plates. All assembly hardware
and plugs are included, but mounting hardware for the assembly must be provided by the customer.
