 NOTES:

The CC-2 Series compact two-stage precision pressure regulator is well suited for instrumentation applications requiring a precise and stable delivery pressure. This regulator was originally designed to meet the needs of the instrumentation industry, however it would also be very useful in many other applications that require a compact 2-stage pressure regulator to supply a precise delivery pressure with fluctuating supply pressures.

Another benefit of using the CC-2 series is that it shares some of its design features and options with the time-proven CPR-1 series pressure regulator. These features and options allow the customer to essentially tailor his regulator to accommodate virtually any application requiring low to moderate flow rates. Unit will also be offered with inlet/outlet pressure gauges, CGA connections and relief valves.

The CC-2 series regulator is manufactured as a standard in Aluminum. Please consult GO Regulator for any optional materials of construction that might be required for toxic or corrosive process gas applications.

The CYL-1 Series is designed as a complete compact pressure control module. The basis of this unit is the economical PR-2 series pressure control valve which is widely used in instrumentation sample systems as well as many other applications requiring maximum reliability. This regulator, when ordered with appropriate gauges and CGA inlet fitting, is designed for use as a compressed gas cylinder regulator for those applications where the corrosion resistance of stainless steel is not a requirement.

The CYL-2 Series is a precision 2-stage regulator well suited for instrumentation applications requiring a precise and stable pressure sources. This series of control valve was developed to meet the needs of the instrumentation industry but is also well suited for other applications requiring precision pressure supply.

The development of this series provides the maximum flexibility that is available in any cylinder regulator. This means that you can select optional diaphragm materials for maximum sensitivity with Teflon-lined stainless steel being standard.

The CYL-3 Series is an economical brass high pressure regulator, designed to accept inlet pressures up to 3,600 psig and delivery outlet pressures from 0-100 psig up to 0-2,000 psig. This single stage brass regulator is perfectly suited for cylinder usage with non-corrosive gases. Good regulation characteristics are provided by a carefully engineered piston sensor. Ease of outlet pressure adjustment is provided by the T-handle, which is offered as standard.

Precision pressure control is now possible with the CYL-20 Series regulator. This 2-stage regulator constructed of 316L SS and Teflon has less than 0.01% outlet pressure change with varying inlet pressures and is designed for use in gas calibration systems and semiconductor materials processing.

With materials of only 316L stainless steel, Teflon and Tefzel, this regulator is suitable for service in corrosive streams, as well as non-corrosive streams with potential surface absorption problems. This regulator accepts inlet pressures up to 6,000 psig and has bubble-tight shutoff. Operating temperature ranges may vary from -40°C up to +260°C and outlet pressure ranges of 0-10 up to 0-500 psig are easily adjusted by a fluted knob.

The CYL-21 Series is a compact cylinder regulator based on the time-proven design of the PR-1 series single stage stainless steel line regulator and is suitable for most corrosive gas cylinder gas applications. While normally used for low and moderate flow service, optional high flow orifices are available.

The standard unit is equipped with CGA connector, integral inlet filter, inlet and outlet pressure gauges and may be ordered with extra inlet or outlet ports for inlet purging, outlet relief valves or other accessory items. When used in service with toxic or explosive gases, we recommend the installation of a captured vent option. This option is a true captured vent cap and not merely a standard cap with a vent port. It comes complete with a CGA fitting and 2" diameter gauges.

The COM-1 Series crossover manifold system consists of two PR-1 type SS regulators (PR-2 type, brass, optional) mounted on a panel mounting type bracket shown with optional gauges. The primary regulator, supplied with a tamper-proof nut, is set at an outlet operating pressure at least 15 psig higher than the secondary regulator (supplied with a standard adjusting knob). As the primary supply source depletes and the operating outlet pressure of the primary regulator falls below the preset operating pressure of the secondary regulator, the secondary regulator takes over. Once this occurs, the secondary regulator can be manually adjusted 1/8 turn clockwise, the secondary regulator is now the primary and the depleted supply source can be replaced.

The COM-2B Series crossover manifold system consists of two PR-1 (stainless steel) type regulators (PR-2 type, brass, optional) built in a single body functioning as the changeover regulators with the common outlet port connected to a single line regulator to provide constant unchanging supply pressure unaffected by supply source depletion. All are mounted on a bracket complete with gauges. As the primary supply source depletes and the operating outlet pressure of the primary regulator falls below the preset changeover pressure of the secondary regulator, the secondary regulator takes over. Once this occurs, the primary regulator can be manually adjusted 1/8 turn counter-clockwise, the secondary regulator is now the primary and the depleted supply source can be replaced.

The COM-2P Series crossover manifold system is a gas delivery system using three PR-1 stainless steel type regulators (PR-2 type, brass, optional). Built on a single body functioning as the changeover regulators with the common outlet port connected to a single line regulator to provide constant unchanging supply pressure unaffected by supply source depletion. All are mounted on a panel complete with two vent valves, an outlet valve and gauges. As the primary supply source depletes and the operating outlet pressure of the primary regulator falls below the preset changeover pressure of the secondary regulator, the secondary regulator takes over. Once this occurs, the primary regulator can be manually adjusted 1/8 turn counter-clockwise, the secondary regulator is now the primary regulator and the depleted supply source can be replaced.
