{"product_id":"national-oilwell-100sd6604-3-in-gd-pg-2b-discharge-valve-assembly","title":"National Oilwell 100SD6604 3 in GD PG-2B Discharge Valve Assembly","description":"\u003cdiv style=\"font-family:Arial,sans-serif;line-height:1.6;color:#333;max-width:800px;\"\u003e\n\u003cp\u003eThis is a new National Oilwell (NOV) discharge valve assembly, part number 100SD6604, cross-referenced on the original box label as 0040-AR-066A-04, designated \"GD DISCH. VALVE ASSY PG-2B\" — a guided-disc (GD) style spring-loaded poppet valve assembly designed for use in the PG-2B series triplex or duplex mud pump discharge valve seats. The assembly consists of a stainless steel body\/retainer cup, a spring-loaded valve disc with a yellow elastomeric seal (visible in photos), a coil return spring, and a cast iron\/steel yoke-style guide frame stamped \"C-6,\" indicating a Class 6 or Group 6 designation typical of NOV pump valve classifications. The 3-inch nominal size refers to the valve bore\/seat diameter, and the guided-disc configuration provides positive, concentric seating for reliable high-pressure shutoff in drilling fluid (mud) pump discharge service. The box is marked \"VALVES LOOSELY ASSEMBLED,\" \"MADE IN U.S.A.,\" and dated 05\/02\/05; the valve body shows the pen-marked lot\/serial notation \"0040-AR-04\" and appears new\/unused with no wear marks on the sealing surfaces. Compatible with National Oilwell PG-2B series pump fluid ends; buyers should confirm seat compatibility and elastomer grade (standard appears to be Nitrile\/Buna-N based on yellow coloration) for their specific service fluid.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
