It operates over an adjustable setpoint range of 240 psi to 3000 psi on rise, with a minimum deadband of 40 psi and a maximum deadband of 250 psi. The switch features an SPDT contact form with screw terminal electrical connections, rated at 10 amps at 125\/250\/480 volts AC and 0.03 amps at 250 volts DC. The wetted components are 416 stainless steel, and the housing is aluminum. Licensed HVAC technicians, pipefitters, and industrial controls electricians are the typical installers for this type of device.\u003c\/p\u003e\u003cp\u003eThis pressure switch is suited for hydraulic, pneumatic, and process piping systems where accurate, repeatable pressure control is required. It connects via a 1\/4 inch female NPTF thread and supports both normally open and normally closed starting positions, allowing flexible integration into control circuits. The 2% repeatability rating makes it appropriate for applications demanding consistent switching performance across a broad pressure range and temperature window of -40 degrees F to 165 degrees F.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable setpoint range: 240 psi to 3000 psi on rise, 200 psi to 2825 psi on fall\u003c\/li\u003e\n\u003cli\u003eSPDT contact form with both normally open and normally closed configurations available\u003c\/li\u003e\n\u003cli\u003e416 stainless steel wetted material for corrosion resistance in demanding media\u003c\/li\u003e\n\u003cli\u003eScrew terminal electrical connections rated up to 480 volts AC and 250 volts DC\u003c\/li\u003e\n\u003cli\u003e2% repeatability for consistent, dependable switching performance\u003c\/li\u003e\n\u003cli\u003eCSA and UL listed; meets CSA Class 3231 02 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sealed piston pressure switch for industrial and commercial fluid control systems requiring a 1\/4 inch NPTF female threaded connection and SPDT switching output.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified controls technician. De-energize all electrical circuits and depressurize the system completely before connecting or disconnecting the switch. Ensure the process fluid and pressure range are compatible with 416 stainless steel wetted surfaces and the aluminum housing before installation. Follow all applicable NEC requirements for electrical connections and local codes governing pressure system service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Sealed Piston Pressure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Adjustable Pressure (Rise)\u003c\/strong\u003e: 240 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Adjustable Pressure (Rise)\u003c\/strong\u003e: 3000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Adjustable Pressure (Fall)\u003c\/strong\u003e: 200 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Adjustable Pressure (Fall)\u003c\/strong\u003e: 2825 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Rating\u003c\/strong\u003e: 10000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Deadband\u003c\/strong\u003e: 40 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deadband\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepeatability\u003c\/strong\u003e: 2%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 125 volts AC, 250 volts AC, 480 volts AC, 250 volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 10A at 125\/250\/480 volts AC; 0.03A at 250 volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Starting Position\u003c\/strong\u003e: Normally Open and Normally Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Connection\u003c\/strong\u003e: Screw Terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted Material\u003c\/strong\u003e: 416 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 165 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5.58 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CSA Class 3231 02, UL\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BARKSDALE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9048-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BARKSDALE","offers":[{"title":"Default Title","offer_id":51542671884594,"sku":"9048-4","price":933.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78da91b792d8227a6bb3734169e65756.jpg?v=1785904297","url":"https:\/\/voomisupply.com\/products\/barksdale-9048-4-sealed-piston-pressure-switch-240-3000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
