The RS Series Medium Duty Single Stage Regulator models are for applications that require high flow rates. This design provides more consistent delivery pressure by minimizing fluctuation over a wide range of inlet pressures. Those regulators are appropriate for industrial/welding, laboratory and general use applications. Certain models feature a ¼" NPT outlet connection for high pressure applications.

FEATURES

• Machined brass body resists corrosion
• 2" reinforced Neoprene diaphragm
• 450 PSIG models have PCTFE seat to accommodate high pressure applications
• Dual inlet filter system extends regulator life
• Hydrogen and Methane models equipped with pipe away relief valves
• Most models include self re-seating pressure relief valve (except for RS-1-1, RS-1A-1, RS-10-2)
• Nickel chrome plated zinc bonnet
• Large 2" gauges wiuth easy to read gradients
• Weight: 3 lbs.
• Three year warranty

The RC Series Heavy Duty Single Stage Regulator models utilize Western's "Pressure Compensated" design. For applications that require high flow rates, this design provides more consistent delivery pressure by minimizing fluctualtion over a wide range of inlet pressure. The unique cartridge design allows for fast, easy replacement of vital parts (seat, nozzle, filter, spring, and seals) without breaking the diaphragm-to-bonnet seal. No special tools are required. These heavy duty regulators are designed to provide high flow rates to meet the requirements of the most demanding cutting, welding, and heating jobs.

FEATURES

• Machined brass body resists corrosion
• 2 3/4" reinforced Neoprene diaphragm
• Self re-seating relief valve in most models protect against over-pressurization (except RC-1-1, RC-1A-1, RC-10-2)
• Dual inlet filtering system extends regulator life
• Large 2 1/2" gauges with easy to read gradients
• Hydrogen and Methane models equipped with pipe away relief valves
• Replaceable Delrin® thrust bushing for easy adjustment
• Weight: 4 lbs. 8 oz.
• Three year warranty
