Description for Barksdale Model 20597 Heavy Duty Hydraulic Regulator
Barksdale's increased sensitivity regulator is a sensitive, pressure-control device used to maintain a pre-determined pressure in a hydraulic circuit. This version offers better reaction time and better set point accuracy. The regulated output pressure is controlled by manually adjusting the spring force to balance the hydraulic loading. 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 fl uid 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 Pressure:Regulated Pressure Range:High SensitivityFull RangeRegulated Pressure Range “F” PrefixPneumatic failsafe motor:High SensitivityFull RangeRegulated Pressure Range “G” PrefixHydraulic failsafe motor:High SensitivityFull RangeFluid Temperature Range:Proof Pressure:5,000 psi (345 bar)300 - 1600 psi (21 - 110 bar)500 - 3300 psi (34 - 228 bar)300 - 1600 psi (21 - 110 bar)500 - 3000 psi (34 - 207 bar)300 - 1600 psi (21 - 110 bar)500 - 3000 psi (34 - 207 bar)-40° to +250°F (-40° to +121°C)7,500 psi (517 bar)Flow:Flow Rate:Cv Inlet:Cv Vent:160 GPM (@ 50 ft/s)17.52.6Porting:Inlet 1:Inlet 2:Outlet: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 Tower:ManualPneumatic Motor modelHydraulic Motor modelStandard O’ring Material:Socket Head Screws:Wetted Parts:Stainless steel (std.)Phosphate coated alloy steel (std.)Option: Stainless steelStainless steel (std.)Phosphate coated alloy steel (std.)Phosphate coated alloy steel (std.)Buna NStainless steel (std.)Stainless steelPneumatic Pilot Motor (“F” prefix):Pilot Motor Working Pressure:Porting:Operating Temperature Range:80 - 120 psi (5.5 - 8.3 bar)1/4” NPT32° to +250°F (0° to +120°C)Hydraulic Pilot Motor (“G” prefix):Pilot Motor Working Pressure:Porting:Operating Temperature Range:400 - 1600 psi (6.9 - 110 bar)SAE for 3/8” Tube (Size -6)-40° to +250°F (-40° to +121°C)Approximate Shipping Weight:Manual:Pneumatic or Hydraulic Motor:67 lbs.
