The Hydraforce NV08-20A-0-N (5401000) is a precision-engineered hydraulic flow restrictor valve designed for robust performance in controlling fluid flow in hydraulic systems. This screw-in, cartridge-style, variable orifice valve allows for the adjustment of fluid flow from fully closed to fully open through a counterclockwise rotation. It features a unique design where adjustments cannot be backed out, ensuring stable operation once settings are locked down. Constructed with hardened parts, this valve offers enhanced durability and longevity. The NV08-20A-0-N is equipped with an aluminum knob for manual adjustments and provides positive shutoff with linear adjustment capabilities. Its compact size makes it ideal for integration into tight spaces within various hydraulic applications. The valve operates effectively within a pressure rating of up to 241 bar (3500 psi), with proof pressure at 345 bar (5000 psi) and burst pressure reaching up to 896 bar (13000 psi). It supports a wide range of operating temperatures from -40 to +120°C (-40 to +250°F) with Buna N seals, extending up to +204°C (+400°F) with fluorocarbon seals. Additionally, this model offers minimal internal leakage at shutoff, measuring approximately 0.32 ml/min (5 drops/min), ensuring efficient operation and reduced fluid loss. The NV08-20A-0-N is compatible with mineral-based or synthetic hydraulic fluids with lubricating properties and can handle fluid viscosities ranging from 7.4 to 420 cSt. For installation, the valve uses an 08-size cavity (VC082) and can be installed without orientation restrictions, providing flexibility in system design. Accessories such as seal kits (SK082XM) are available to ensure proper maintenance and performance optimization over the lifespan of the valve.
