The Model 771 Current-to-Pneumatic Transducers designed as a cost-effective valve service transducer. The Model 771 receives the output of an electronic signal, such as a PID control function, and drives a control valve via the transducer until the control function is satisfied.

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. The 91-HF Filter regulator is a quality unit that is ideal as an economical alternative for control of process applications. It is used extensively to supply air to pneumatic controllers, transmitters, transducers, valve positioners, air cylinders, and a wide range of pneumatic control systems.

Stable output and repeatability
Corrosion resistant construction
Depth filter
Low droop at high flow levels
Tight shut-off

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.

A simple petcock permits the filter to be blown down periodically.

Solid brass construction delivers exceptional durability
Natural wool filter medium provides unsurpassed coalescing action

Series 61 Booster Relays

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.
Epoxy powder coating provides excellent corrosion resistance

Input pressure acting upon the effective area of the upper diaphragm, produces a force that is opposed by the output pressure exerted upon the effective area of the lower diaphragm. The opposing forces are in a direct 1:1 ratio.
