Description for Barksdale Series S20517 Stainless Steel Pressure Regulator

Barksdale's pressure regulators are sensitive pressure-control devices used to maintain a pre-determined pressure in a hydraulic circuit. The Stainless Steel Regulators offer corrosive-resistant, 316 stainless steel, units with SAE J518-2 code 62 flanges, which are standard with this series. Code 62 flanges are industry proven leak-free connections suited for higher pressure that offer ease of installation.Designed to provide years of trouble-free operation and virtually zero leakage, the Shear-Seal® design uses fluid pressure to maintain a leak-free metal-to-metal seal that improves with use. The shearing action between the rotor & pressure seal continually laps the mating surfaces and prevents contaminates from lodging between the sealing surfaces. The result is a valve that doesn’t wear out – but wears in over time, providing you superior control consistently through the entire life of the product.General Specifications*Pressure:Supply/Inlet Pressures:Regulated Pressure Range at 3,000 psi Supply Pressure:High Sensitivity:Full Range:Regulated Pressure Range at 5,000 psi Supply Pressure:High Sensitivity:Full Range:Ambient Temperature Range:Inlet Proof Pressure:Case Proof Pressure:3,000 psi (207 bar)5,000 psi (345 bar)300 - 1600 psi (21 - 110 bar)300 - 2800 psi (21 - 193 bar)500 - 1600 psi (34 - 110 bar)500 - 3000 psi (34 - 207 bar)-30° to +185°F (-34° to +85°C)7,500 psi (517 bar)4,500 psi (310 bar)Flow:Flow Rate:Cv Outlet:Cv Vent:120 GPM (@ 50 ft/s)17.51.6Porting:Supply 1:Supply 2:Outlet (Regulated):Vent:1” SAE J518 code 62 flange; NPT or SAE porting option1” SAE J518 code 62 flange; NPT or SAE porting option1-1/2” SAE J518 code 62 flange; NPT or SAE porting option1” SAE J518 code 62 flange; NPT or SAE porting optionMaterials of Construction:External ComponentsBody, Flanges, & Spring Housing:Adjusting Handle, Gear Housing:(for motorized models)Hardware:Wetted ComponetnsSlide, Inlet, Vent & Blocking Plates, Pressure Seals:Other Internal Wetted Components:O’ring Material:Backup Ring Material:316 Series stainless steelNickel Plated 17-4 ST STL316 Series stainless steel400 Stainless steel300 Series stainless steelBuna NPTFEPneumatic Pilot Motor (“F” prefix):Pilot Motor Working Pressure:Porting A & B:Operating Temperature Range:Painted steel80 - 120 psi (5.5 - 8.3 bar)1/4” NPT-30° to +185°F (-34° to +85°C)Hydraulic Pilot Motor (“G” prefix):Pilot Motor Working Pressure:Porting A & B:Operating Temperature Rating:Painted steel400 - 1600 psi (6.9 - 110 bar)SAE for 3/8” tube (Size -6)-30° to +185°F (-34° to +85°C)Approximate Shipping Weight**:Manual Unit:Pneumatic Motor Unit:Hydraulic Motor Unit:85 lbs.
