Description for Barksdale Series L20517 Land Pressure Regulator
Barksdale's pressure regulators are sensitive pressure-control devices used to maintain a pre-determined pressure in a hydraulic circuit. The regulated output pressure can be controlled either by the force of a spring, or a motor (hydraulic or pneumatic). Design features ensure excellent accuracy, repeatability and high flow coefficients.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 Inlet:Cv Vent:120 GPM (@ 50 ft/s)17.51.6Porting:Supply 1:Supply 2:Outlet (Regulated):Vent:1” NPT Standard, SAE Optional1” NPT Standard, SAE Optional1-1/2” NPT Standard, SAE Optional1” NPT Standard, SAE OptionalMaterials of Construction:Body, Flanges, & Spring Housing:Slide, Inlet, Vent, & Blocking Plates:Hardware:O’ring Material:Backup Ring Material:Socket Head Screws:Wetted Parts:Phosphate coated carbon steel/ductile iron400 Series stainless steelPlated alloy steel, 300 series stainless steelBuna NTeflonZinc plated alloy steel (std.)Stainless steelPneumatic Pilot Motor (“F” prefix):Pilot Motor Working Pressure:Porting A & B:Operating Temperature Range:80 - 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:400 - 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:70 lbs.
