The Hydraforce NV10-20D-0-V (5411301) is a screw-in, cartridge-style, variable orifice, hydraulic flow restrictor valve designed for precise fluid control in hydraulic systems. This model features a variable orifice that adjusts from fully closed to fully open with a counterclockwise rotation, allowing for linear adjustment of flow. The NV10-20D-0-V is engineered with hardened parts to ensure durability and long life, and it includes an option for an aluminum knob for ease of adjustment. Notably, the valve settings are secure as adjustments cannot be backed out unintentionally and can be locked down once the desired setting is achieved. This valve offers positive shutoff capabilities and is designed to fit industry-common cavity VC102, making it versatile for integration into various hydraulic systems without the need for extensive modifications. It supports a wide range of operating temperatures depending on the seal material used—from -40°C to +212°F with Buna N seals up to 15°F to 400°F with fluorocarbon seals. The NV10-20D-0-V can handle pressures up to 3500 psi with a proof pressure of 5000 psi and a burst pressure of 13000 psi. The NV10-20D-0-V is suitable for use with mineral-based or synthetic hydraulic fluids that have lubricating properties within a viscosity range of 7.4 to 420 cSt. Its maximum internal leakage at shutoff is minimal at approximately one drop per minute, ensuring efficient operation and minimal fluid loss. The unit's compact design weighs only 0.30 lb (Option A) and offers corrosion protection up to 960 hours in salt spray per ASTM B117 standards, highlighting its suitability for challenging environments.
