The GO Regulator CYL-21 Series is a high-performance cylinder pressure regulator designed for precise pressure reduction from compressed gas cylinders in analytical, laboratory, industrial, and specialty gas applications. The regulator delivers stable outlet pressure control with excellent sensitivity, repeatability, and reliable shutoff performance while operating under high inlet pressure conditions. Its compact but robust design supports both portable and permanent gas distribution installations where dependable pressure regulation is critical.

The CYL-21 Series utilizes a diaphragm-operated pressure reducing mechanism engineered to maintain stable outlet pressure as cylinder pressure decreases during operation. Standard construction materials include 316 stainless steel and brass, with optional Monel and Hastelloy configurations available for corrosive, toxic, and high-purity gas service. Multiple seat and elastomer material options are available to optimize chemical compatibility, leakage performance, and service life.

Available configurations include various CGA cylinder connections, multiple outlet pressure ranges, pressure gauge ports, relief valve options, and panel mounting arrangements for flexible integration into instrumentation and gas delivery systems. Typical applications include calibration gas systems, analytical instrumentation, semiconductor support equipment, specialty gas handling, gas analyzers, laser gas systems, laboratory gas supply, sample conditioning systems, and industrial process installations requiring reliable cylinder pressure regulation.
