Barksdale Series S20517 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.

With over 70 years experience, Barksdale has been at the forefront of innovation with patented designs like our Shear-Seal® technology used in our valves with great success in demanding applications such as work holding, oil exploration and processing. Invented in 1949, Barksdale engineers have successfully built upon this technology expanding its product portfolio and have continued to offer best-in-class solutions to our customers in safety critical applications. This same technology was again reinvented and incorporated in our air suspension valves that have been used in the transportation industry with much success since 1992.  In the 1980’s, Barksdale entered the transducer business and has developed a complete line of pressure transducers and transmitters for general industrial, intrinsically safe and hazardous applications. Our latest product innovation is our BiT -- Barksdale Intelligent Transmitter with HART®, which offers big performance in a small package.

BiT: Barksdale Intelligent Transmitters

Barksdale Series 450E

Barksdale Intelligent Transmitters (BiT), Series 450E and H450E are BiT's Intrinsically Safe models. Barksdale has been manufacturing explosion proof transmitters for many years allowing their use in Class I Div 1 or Zone 0, 1 hazardous location. So why introduce an Intrinsically Safe (I.S.) model?  Explosion proof wiring requires metal conduit and special explosion proof sealing glands and junction boxes which are not practical for equipment that needs to be quickly rigged or broken down to modular sections to transport on roads to the next location such as Drilling, Frac or other mobile equipment. I.S. protection concept allows use in the same hazardous areas as explosion proof only with the same flexible cables and electrical connections used in ordinary locations including industrial and military style connectors used on our BiT 450 ordinary location models. Maintenance of systems is greatly simplified with quick electrical disconnects and no expensive explosion proof boxes that are susceptible to scratches on sealing flame path surfaces during maintenance. Barksdale’s new intrinsically safe models also include advanced Thin-Film and HART technology providing all of the advantages of our other models including high accuracy and long term stability.

Features

• Intrinsic safety certification with ATEX, IECEx and CSA approvals
• Lightweight, compact and all-welded rugged stainless steel construction
• High performance sensors
• Optional HART® communication protocol with diagnostics & field calibration, reducing maintenance time and cost; 10:1 turndown ratio for re-ranging, maintaining high accuracy and allowing one part number for multiple pressure ranges
• High accuracy: ±0.1% and 0.25% FSO, (L,H,R)
• Additional CSA certification for ordinary locations
• Factory sealed IP66 & IP67 and NEMA 4X enclosure
• CE, NACE compliant and superior EMC/EMI protection
• RoHS / REACH Compliant

Barksdale Series 423X, 425X, 426X

Barksdale's 420X Series Explosion Proof Transducers prevent an explosion from occurring when operated in a Division 1 environment. Barksdale's 420X Series transducers prevent personal injury and machinery damage by preventing the explosion the first place. Energy generated within the transducer is of such a low level that intermittently present flammable vapors will not be ignited. External zener barriers are not required in order to meet UL requirements for a non-incendive installation. The lower cost of not having to install zener barriers means that the positive aspects of intrinsically safe and explosion proof are combined in Barksdale non-incendive transducers. Three models are available: Series 423X (0-5V), Series 425X (4-20mA) and Series 426X (0-10V).

Features

• Diffused silicon sensor for high accuracy
• Explosion proof enclosure for hazardous locations
• Superior EMI, ESD and RFI protection
• Rugged stainless steel construction
• NEMA 4X, 7 and 9
• ATEX/IECEx certification for 425X Series only
• Modular concept
• Built-in high pressure snubber (2000 psi and above)
• cULus, CE approved

Barksdale Series 443, 445, 446

Intrinsically Safe Transducer

Barksdale's 440 Series Intrinsically Safe Transducers provide high accuracy pressure measurement when operating in Class I, Division I environments. Intrinsically safe transducers prevent personal injury and machinery damage by preventing the explosion in the first place. External zener barriers are required in order to meet UL requirements for an intrinsically safe installation. The higher cost of having to install a zener barrier is offset with the comfort of knowing that an explosion will not occur within normal operating conditions. Three models are available: Series 443 (0-5V), Series 445 (4-20mA) and Series 446 (0-10V).

Features

• High accuracy
• Protection in hazardous environments, Class I, Div 2
• Superior EMI, ESD and RFI protection
• Rugged all-welded stainless steel construction
• NEMA 4X
• Built-in high pressure snubber (2000 psi and above)
• cULus, CE approved
