The inlet valve controls airflow into the pump cylinder on each intake stroke, allowing the piston to draw in atmospheric air while preventing backflow. It is a direct service part for maintaining proper compression efficiency in piston-style air compressor assemblies. HVAC technicians, industrial service techs, and equipment maintenance personnel typically service this component when a pump shows reduced output, excessive noise on intake, or visible valve wear during routine teardown.\u003c\/p\u003e\n\u003cp\u003eThis inlet valve is intended for GAST 48 Frame piston pump configurations commonly found in medical, laboratory, industrial, and HVAC equipment applications. The 48 Frame designation refers to the motor frame size standardized by GAST for this pump family. It is a fit-for-purpose replacement part suited to single-stage piston pump assemblies where maintaining clean, controlled air intake is critical to system performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect replacement inlet valve for GAST 48 Frame piston pumps\u003c\/li\u003e\n  \u003cli\u003eControls one-way airflow into the pump cylinder on the intake stroke\u003c\/li\u003e\n  \u003cli\u003eMaintains compression efficiency by preventing intake backflow\u003c\/li\u003e\n  \u003cli\u003ePackaged as a single unit for individual pump service\u003c\/li\u003e\n  \u003cli\u003eLightweight component at 1 pound for easy handling during service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement inlet valve for GAST 48 Frame piston pumps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with piston pump service. Always disconnect and lock out electrical power to the compressor unit before disassembling any pump components. Inspect the valve seat and surrounding bore for wear or debris before installing the new valve, and ensure the seating surface is clean and undamaged. Refer to the GAST service manual for the specific pump model to confirm proper valve orientation and reassembly sequence.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Inlet Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: GAST 48 Frame Piston Pump\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40151502\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GAST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AF530\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GAST","offers":[{"title":"Default Title","offer_id":51718004146482,"sku":"AF530","price":35.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a17ca7eb459c7633fd91d18f94279e3.jpg?v=1788548389","url":"https:\/\/voomisupply.com\/products\/gast-af530-air-compressor-inlet-valve-48-frame","provider":"Voomi Supply","version":"1.0","type":"link"}
