Type 100 Precision Air Pressure Regulator Dependable stable and highly precise precision regulation The Type-100 is a high precision, multi-stage pressure regulator. This pressure controller provides the highest level of regulation accuracy and repeatability available. The Type-100 is ideal for applications that call for the utmost of control and maximum stability under variable operating conditions. A stainless steel measuring capsule is used as a sensing element to activate the high gain servo balanced control mechanism in which the main valve is controlled by a pilot valve.This allows for greater accuracy and eliminates many of the problems associated with conventional regulators using range springs and diaphragms.
