Teledyne 483-3/8D2-2 Instrumentation Sensor Module

The Teledyne 483-3/8D2-2 Check Valve provides automatic one-way flow control in hydraulic and fuel systems, preventing reverse flow to protect pumps, regulators, and upstream components from backflow. This straight‑through inline valve uses a spring‑loaded poppet with an aluminum alloy body, a stainless steel Type 304 poppet, and a synthetic rubber seat, rated to 3,000 PSI and 200°F (93°C) with 3/8 in NPT female connections for vertical mounting, and it is compatible with fuel, oil, and hydrocarbon fluids. Commonly installed in Teledyne Fluid Systems hydraulic power units, fuel distribution systems, industrial machinery, aerospace ground support equipment, and OEM fluid control applications, it is also listed as a common replacement for Parker-Hannifin 483-3/8D2-2 and Curtiss-Wright 483-3/8D2-2 models.
