Description
The Type 90 Miniature Precision Air Pressure Regulator delivers exceptional pressure regulation accuracy and repeatability in a compact, lightweight package. Designed for applications where installation space is limited but precise pressure control is critical, the Type 90 utilizes a force-balanced pilot control system that maintains output pressure within 0.05 psig (3.44 mbar), providing stable and repeatable performance across varying operating conditions.
Unlike conventional miniature regulators that sacrifice performance for size, the Type 90 combines precision regulation with substantial flow capacity. Its force-balanced design continuously compensates for changes in supply pressure and downstream demand, helping maintain consistent outlet pressure in instrumentation, analytical equipment, calibration systems, and OEM pneumatic applications.
For manufacturers seeking RoHS-compliant pneumatic components, the Type 90 is available with Option “M” no-brass construction. This lead-free configuration helps OEMs and equipment manufacturers address RoHS 2 compliance requirements and concerns surrounding lead-containing brass components while maintaining the same precision pressure control performance expected from ControlAir regulators.
Designed, assembled, and tested in New Hampshire, USA, the Type 90 provides a dependable solution for OEM equipment, laboratory instrumentation, semiconductor systems, medical devices, and industrial automation applications requiring compact, high-performance pressure regulation.
