Type 27 Restrictor Assembly
The Type 27 Restrictor Assembly includes the adjustable orifice
and an integrated check valve to protect the diaphragm from
damage in case of a sudden spike in back pressure to the
system.

The Type 27 Restrictor is connected to the main body of the
Series 22 pilot by two socket head cap screws and two pressure
retaining pins.

Care should be taken to avoid damaging the pin O-Rings during
assembly.
The variable orifice can only be removed from the Restrictor
block after separation from the Series 22 block.

- Restrictor Block Assembly
The check valve can be removed from the Restrictor block while
attached to the Series 22 block. Care should be taken to assure
that the check valve is installed in the proper orientation as it is
easily reversed due to its universal nature. Flow should be from
the bottom (Cap side) to the Loading port.
The Type 27 Restrictor block has multiple options for control line
mounting.

The standard option is to plug ports A and B. The ½” NPT Sense
port is connected to the Upper Actuator housing connection
(Sense Connection) on the FlowMax НР. The Loading port is
connected to the Lower Actuator housing connection on the
FlowMax НР.
Other control options are available. Please contact your Mooney
Representative for additional information.
