The booster may also be directly mounted to the actuator by using an actuator yoke mounting bracket (see figure 5)
or casing mounting bracket.
Pressure Connections
The input signal connection is 1/4 NPT. The supply and output connections are 3/4 NPT (minimum pipe size
recommended for nipple mounting is 1/2 NPT). Connections to the volume booster should be made as indicated in
figure 3. Connections for two typical applications are shown in figure 2. Ensure that the piping is of proper size to meet
the capacity demands of the booster and that you equip the actuator with properly sized input connections.
