REGULATORS FOR SPECIFIC APPLICATIONS

SINGLE-STAGE REGULATORS FOR NITROUS OXIDE AND CARBON DIOXIDE (MODELS SG9011, SG9012, SG9014) Nitrous Oxide and Carbon Dioxide frequently cause ordinary regulators to freeze up. Models SG9011, SG9012 and SG9014 will handle these gases at flow rates up to 100 scfh at 70 F without freeze-up and without the need for electrical connections. Note: These regulators are not manufactured to meet FDA standards and should not be used for medical gases. Regulators for medical gases are shown on page 30. Filter in Seat Assembly traps foreign matter, extends regulator life and reduces maintenance. Unique Regulator Design operates at flow rates up to 100 scfh at 70 F without freeze-up. Pressure Relief Valve protects regulator and downstream system from overpressurization.

In applications where backpressure in excess of 2 psig can be expected, a regulator with a flowmeter should be used. Teflon Washers for CGA 320 (package of 25) SG6076 26 ADVANCED Specialty Gas

SINGLE-STAGE REGULATORS FOR ATOMIC ABSORPTION, ACETYLENE (MODEL AG9048) This regulator is specifically designed for use with Atomic Absorption or Technical Grades of Acetylene. Although similar to our Model APD diffusion resistant regulator, its delivery pressure is limited to 15 psig. Limited Pressure Adjustment does not allow delivery pressure above 15 psig as recommended for Acetylene service. Type 316L Stainless Steel Diaphragm minimizes diffusion of air into regulator and eliminates off gassing associated with elastomeric diaphragms, thus maintaining gas purity. Cartridge (Encapsulated) Seat Assembly provides for ease of maintenance and repair. Filter in Seat Assembly traps foreign matter, extends regulator life and reduces maintenance. Threaded Holes in Rear of Regulator permit front panel mounting. 1 8" NPT Female Bonnet Vent Port allows bonnet to be connected to a vent line or disposal system as a precaution in the unlikely event of a diaphragm failure. Red-Lined Pressure Gauge provides visual indication should delivery pressure exceed allowable withdrawal pressure of 15 psig.

HIGH PURITY REGULATORS FOR GAS WITHDRAWAL FROM CRYOGENIC CONTAINERS (LC SERIES) The LC Series Regulators are specially designed for use on the gaseous withdrawal port of cryogenic liquid containers. These metal diaphragm, single-stage regulators are ideal for applications requiring both high flow and diffusion resistant pressure regulation. These LC Regulators have been specially designed to accept a maximum inlet pressure of 3000 psig, allowing them to be used on high pressure compressed gas cylinders as well. In addition to the high inlet pressure feature, new higher delivery pressure ranges of 350 psig and 500 psig are available for special laser cutting applications. Specially Designed for Gaseous Withdrawal from Cryogenic Liquid Containers. High Pressure Regulator Design accepts inlet pressures up to 3000 psig allowing it to be used on high pressure cylinders as well as liquid containers. High Flow Capacity capable of flow rates in excess of 1500 scfh. Stainless Steel Diaphragm minimizes diffusion of air into regulator and eliminates offgasing associated with elastomeric diaphragms, thus maintaining gas purity. Tamper proof, self-seating internal relief valve protects regulator from overpressurization. Filter in Seat Assembly traps foreign matter, extends regulator life and reduces maintenance. Diaphragm Seal Outlet Valve provides for flow shut-off while maintaining gas purity (Valve may reduce regulator flow capacity).

SINGLE-STAGE, TIED SEAT REGULATORS FOR SILANE AND DICHLOROSILANE (SG3860 SERIES) These regulators are specifically designed to handle the unique properties of Silane and Dichlorosilane. Type 316 Stainless Steel Construction provides maximum corrosion resistance. 2 1 2" Stainless Steel Gauges read easily for more precise settings. Tied Seat (tied diaphragm) reduces premature regulator failure caused by silicon dioxide build-up on seat created by reaction of silane with air. Unique Regulator Design permits regulator to be used with low vapor pressure gases such as Dichlorosilane. Diaphragm Seal Outlet Valve maintains gas purity. Rupture Disk Assembly (Model SG3862, SG3865 & SG3866 Only) prevents overpressurization of regulator and downstream system and allows for connection to a disposal system. Bonnet Vent Connector provides 1 8" NPT female port allowing bonnet to be connected to a vent line or disposal system as a precaution in the unlikely event of a diaphragm failure. Internal (Inboard) Helium Leak Test and Test Report determines inboard leak rate; test report certifies leak rate of less than 2 x 10 8 sccs air equivalent.

TWO-STAGE CYLINDER REGULATORS FOR VERY LOW DELIVERY PRESSURES (MODEL TSC) The Model TSC Regulator provides highly accurate pressure reduction of inlet pressures up to 3000 psig down to delivery pressures as low as 0.3 to 3 psig. The two-stage design provides constant outlet pressure regardless of changes in cylinder (inlet) pressures. The Model TSC is suitable for use with noncorrosive gases where high purity is not required. Typical applications include low pressure purging, inert blanketing of chemical or flammable storage units, or control of fuel to burners. Large 3" Diaphragm in second stage, allows for accurate control of delivery pressures down to 0.3 psig. Two-Stage Regulator Design ensures constant delivery pressure over varying inlet pressures. Sintered Metal Filters (in inlet port and between stages) trap foreign matter, extend regulator life, and reduce maintenance. Pressure Relief Valve protects regulator from overpressurization. 1-Ounce Graduations on a 21 2" Outlet Gauge allow for enhanced readability at very low pressure settings. Outlet Metering Valve provides flow control.

ADJUSTABLE BACK PRESSURE REGULATORS FOR HIGH PURITY GASES (MODELS ABPB, ABPS) These metal diaphragm, high purity back pressure regulators are specially designed to control inlet pressure. Unlike pressure reducing regulators, these devices control inlet pressure rather than outlet or downstream pressure. They operate like highly sensitive, adjustable relief valves. The inlet (system) pressure is controlled by relieving pressure through the regulator from the system to maintain pressure at or below a desired level. Back pressure regulators are commonly used to prevent overpressurization of storage vessels, fluid sampling systems, compressor and pumping systems. Model BPB is manufactured from brass bar stock and is designed for noncorrosive gases; Model BPS, which is constructed from Type 316L SS bar stock, is suitable for use with corrosive gases. Convoluted 316 SS diaphragm provides excellent accuracy, high sensitivity, and close tolerances on crack-reseat pressure relationships. High Purity Regulator Design permits vacuum purging of regulator. Threaded Holes in Rear of Regulator permit front panel mounting. Captured Venting Configuration provides 1 16" NPTF vent port and stem packing allowing for complete capturing of bonnet when connected to a vent line or disposal system. Mounting Ring permits regulator to be panel mounted. Internal (Inboard) Helium Leak Test and Test Report determines inboard leak rate; test report certifies leak rate of less than 2x10 8 sccs air equivalent. External (Outboard) Helium Leak Test and Test Report determines leak rate of gas from regulator to atmosphere; test report certifies leak rate of less than 5x10 7 sccs air equivalent.
