Description
The Type 100 Precision Air Pressure Regulator delivers the highest level of regulation accuracy, repeatability, and stability available in the ControlAir precision regulator portfolio. Designed for demanding applications requiring exceptionally stable output pressure under changing operating conditions, the Type 100 utilizes a multi-stage, servo-balanced control system with a stainless steel measuring capsule to achieve regulation accuracy up to 0.1%.
Unlike conventional regulators that rely on range springs and diaphragms, the Type 100 uses a pilot-operated design that continuously compensates for fluctuations in supply pressure and downstream demand. The result is highly accurate pressure control, minimal droop, outstanding sensitivity, and exceptional repeatability for calibration, testing, measurement, and precision automation applications.

These performance characteristics enable highly stable pressure control, rapid response to system changes, and exceptional repeatability in precision pneumatic applications. The servo-balanced pilot control mechanism minimizes the influence of inlet pressure variations while maintaining consistent output pressure under dynamic conditions.
How to Select the Right Configuration
Selecting the correct Type 100 configuration depends on your application requirements:
Choose the Appropriate Pressure Range
- Low Range (100LR): 0.5–25 psig
- Standard Range: 2–40 psig
- Standard Range: 2–60 psig
- Standard Range: 2–120 psig
Match Flow and Exhaust Requirements
- Standard models provide excellent regulation performance for most applications.
- High Relief (100HR) and Extra High Relief (100EHR) models provide faster exhaust performance for dynamic systems and counterbalance applications.
Select the Proper Installation Style
- Standard panel or pipe mounting
- Bottom Port (100BP) for manifold mounting
- Plunger Actuated (100PL)
- Motorized (100M) for remote pressure adjustment

FAQs
What makes the Type 100 a precision regulator?
The Type 100 uses a stainless steel measuring capsule and servo-balanced pilot-operated control mechanism to achieve regulation accuracy up to 0.1%, exceptional repeatability, and stable output pressure under changing operating conditions.
What is droop and why does it matter?
Droop is the decrease in outlet pressure as flow demand increases. The Type 100 minimizes droop, helping maintain accurate pressure control even when downstream demand changes.
When should I choose the low-range model?
The Type 100LR is ideal for applications requiring highly accurate control below 25 psig, such as calibration equipment, air gauging, and laboratory instrumentation.
What is the benefit of high-relief and extra-high-relief models?
These configurations provide faster exhaust capability, allowing output pressure to decrease more rapidly when system demand changes. They are commonly used in counterbalance systems and applications requiring rapid pressure decay.
How does the Type 100 maintain pressure stability?
A pilot valve continuously controls the main valve through a high-gain servo-balanced mechanism. This design compensates for inlet pressure fluctuations and changing flow demand, resulting in highly stable outlet pressure.
