Ideal for use in testing environments, the Orion 2C and Orion 3A pneumatic pressure controllers provide unrivaled performance in a variety of industrial applications.

Both the 2C and 3A utilize an exclusive precision vernier for exact “dial in” of pressure settings. These easy-to-use manifolds feature soft seat construction and an adjustable stop that resists over tightening. Fingertip adjustment provides ultra-fine measurement that eliminates overshoot. Two test ports on panel mountable units allow for multiple applications.

The Orion 2C offers up to 3000 psi and vacuum, while the all stainless steel Orion 3A controls up to 10,000 psi and vacuum. Cased models have a test port located on front as well as an input and vent port on back of unit. Some versions also have an additional test port on back of unit. Regardless of the environment, choose the industry-leading Orion for high-quality, high-pressure control.

Using an adaptor assembly, to combine one of the cased models with a DUT, Hand-Held or Digital Gauge, will provide a means of attaining accurate readings and ultra-fine “dial in” of target value.
