Pneumatic Supply
The BR400 and BR200 Booster Relays require a source of clean, dry, oil-free, instrument grade air to ANSI/
ASA-57.3 1975 (R1981) or ISA-S7.3-1075 (R1981).

Pneumatic Connections
The pneumatic connection locations are shown on Figure 1 and are also stamped on relay body. The supply and
output connections are 1/4" NPT and the signal connection is 1/4" NPT. The supply and output tubing should be a
minimum of 1/2". Blow out all piping prior to connecting to booster. Use of a soft setting anaerobic hydraulic seal,
such as Loctite Hydraulic Seal 542 is recommended on the male threads of all connections.
Installation
The booster relay should be close coupled to the actuator. Use of a short ½" pipe nipple between the relay output
and the actuator provides both the pneumatic connection and mounting means. The preferred orientation is with
the exhaust openings pointing down; however horizontal mounting is acceptable.

150 psi (10.3 bar)
At least 18°F (10°C) below minimum anticipated ambient temperature.
Filtered to below 5 microns.
Less than 1 ppm w/w or v/v.
Free of all corrosive contaminants and hazardous gasses, flammable or
toxic.
Do not use an excessive amount of hydraulic sealant as it will
not set and may migrate into the pneumatic passages.
Do not use pipe thread sealant tape on pneumatic fittings, as
it tends to shred small particles which can cause instrument
malfunction.
