The Hydraforce NV08-20C-0-N (5401200) is a screw-in, cartridge-style, variable orifice hydraulic flow restrictor valve designed for precise fluid control in hydraulic systems. This model operates by increasing its orifice size from fully closed to fully open with a counterclockwise adjustment rotation. It features a design where adjustments cannot be backed out of the valve, ensuring stable settings that can be securely locked down once the desired flow rate is achieved. Crafted with hardened parts for enhanced durability and longevity, the NV08-20C-0-N also offers an aluminum knob option for improved manual control. It ensures a positive shutoff and provides linear adjustment, allowing for precise flow regulation within compact systems. The valve is characterized by its robust pressure ratings which include a maximum operating pressure of 3500 psi, proof pressure of 5000 psi, and a burst pressure of 13000 psi. Temperature adaptability is another key feature with operating fluid temperatures ranging from -40 to 250°F with Buna N seals, -15 to 400°F with fluorocarbon seals, and -65 to 225°F with polyurethane seals. This versatility makes it suitable for various hydraulic fluids including mineral-based or synthetic types with lubricating properties. Additional specifications highlight its minimal internal leakage at shutoff (approximately 5 drops/min), corrosion protection up to 960 hours in salt spray per ASTM B117, and compatibility with VC082 cavity installations. The NV08-20C-0-N weighs around 0.26 lb and has an internal wetted surface area of approximately 9.36 in², making it an optimal choice for efficient and reliable fluid control in diverse hydraulic applications without orientation restrictions during installation.
