Pneumatic Relays and Air Filters

Air Filters 2306 and Filter Regulator 91-HF

Model 91-HF Filter-Regulator

The Model 91-HF Filter-Regulator is designed to provide clean, accurate air pressure to instruments, valves, and other automatic control equipment.  The filter regulator has been proven to provide long lasting corrosion resistance in harsh industrial environments. .

Model 2306 Instrument Air Filter

The Model 2306 instrument air filter is used to remove dirt, oil, water, and other impuriteis from an instrumetn-air supply.  The highly efficient instrument-air filter uses the principle of coalescence to trap fine particles in a dripwell.


Booster Relays - 61H and 61VH

The series 61 Booster Relays reproduce pneumatic signals in a 1:1 ratio for applications where input isolation or increased flow capacity are required.

61H is a High-Capacity Booster Relay designed to improve the stroking speed of large diaphragm valves.

61VH is a High-Capacity Booster Relay designed for use on control valve actuators that require very fast stroking speeds.  Both 61H and 61VH feature a stabilizing bypass needle valve between the input and output, which eliminates the need for an externally piped bypass.
