Restek Datasheets for Gas Pressure Regulators

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only.

Product Name Notes
Mini-Regulator for natural gas and refinery gas standards 0–300 psig inlet pressure range. 0–15 psig outlet pressure range. Supplied with 0–15 psig outlet pressure gauge, brass CGA 170 nut and nipple.
Gas Regulators -- Model 22690/22691 for use with 14-liter and 48-liter Scott/Air Liquide Transportable Gases Use the CGA 160 inlet connection with 14-liter Scott/Air Liquide Transportable Gases. Use the CGA 165 inlet connection with 48-liter...
Backpressure Regulators Backpressure regulators can improve detector performance by preventing bubble formation in the detector flow cell. They also are useful in post-column reaction lines and between detectors and fraction collectors in...
Silcosteel®Regulators -- Dual Stage & Single Stage CEM Continuous Emission Monitoring Environmental Stack and Gas Emission Standards Low level sulfur and mercury analysis Reactive or corrosive gases Off-shore platform systems Corrosive and salt water exposure Outlet pressure:0...
Dual-Stage Ultra-High Purity -- Stainless Steel Gas Regulators Most stable outlet pressure control. Secondary pressure regulation not needed.
Dual-Stage Ultra-High Purity Chrome-Plated -- Brass Gas Regulators Oxidation-resistant, chrome-plated. Most stable outlet pressure control. Secondary pressure regulation not needed. Most widely used regulator. Less internal volume than stainless steel gas regulators.
Single-Stage Ultra-High Purity -- Chrome-Plated Brass Gas Regulators Oxidation-resistant, chrome-plated. Use when there is secondary pressure regulation downstream. Identical gas purity protection as with dual-stage gas regulators.
Ultra-High Purity Chrome-Plated Brass -- Line Gas Regulator Oxidation-resistant, chrome-plated. Use where you need to reduce the line pressure by 20 psig (138 kPa) or more. Same purity protection as high-pressure cylinder regulators.
Spectra Gas 7621 High-Purity VOC Regulator Single-stage, stainless steel. Two pressure gauges and CGA-180 fitting. 3,000 psig maximum inlet pressure. Stainless steel diaphragm and Kel-F® seat. 1/8-inch tube compression outlet. Low internal volume: 3.03 cc.
Single-Stage Ultra-High Purity -- Stainless Steel Gas Regulators Use when there is secondary pressure regulation downstream. Identical gas purity protection as with dual-stage gas regulators.
