Type 200 Precision Air Relay
With positive and negative bias adjustment
The Type 200 Precision Air Relay is a pilot-operated, multistage
1:1 relay with a positive and negative bias adjustment
capability. It accurately reproduces a signal pressure plus or
minus the bias setting with consistent repeatability. Output
control and stability are maintained through a high-gain-servo
balanced control mechanism activated by a highly sensitive
stainless steel measuring capsule.

Controls output pressure to within 0.1%
•Positive and Negative Bias Capability
When adjusted for positive bias, output is directly proportional
to the input signal plus the bias setting. Output pressure can
never go below the value of the bias setting regardless of signal
pressure. When set for negative bias, the output pressure will
remain at minimum until the signal pressure is some value
greater than the negative bias
•Internal Bias Adjustment
The standard Type 200 is provided with an internal bias
adjustment screw, which prevents casual tampering with the
bias setting
•External Bias Adjustment
The Type 200EB is available with an optional external bias
adjustment screw, which allows easy access to the bias setting
•High Relief Capacity
The Type 200HR provides an increased exhaust capacity. Its
highflow relief valve ensures quick “blow down” for release
of downstream pressure
•Stable Output
Highly stable under variable operating conditions
Models
