The Hydraforce NV10-20B-0-N (5411100) 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 value from fully closed to fully open with a counterclockwise adjustment rotation. It features a robust design with hardened parts ensuring long life and durability. The valve adjustments are secure as they cannot be backed out unintentionally, and desired settings can be locked down to prevent tampering. This valve is notable for its positive shutoff capability and linear adjustment mechanism, providing users with precise control over flow rates. It is compatible with industry-common cavity VC102, facilitating easy installation across various applications. The NV10-20B-0-N can handle pressures up to 241 bar (3500 psi) and withstand proof pressures up to 345 bar (5000 psi), with burst pressures reaching up to 896 bar (13000 psi). Temperature adaptability is another strength of this model, operating efficiently within fluid temperatures ranging from -40°C to +100°C (-40°F to +212°F) when equipped with standard Buna N seals, and it can handle even broader temperature ranges with alternative seal materials. The valve's corrosion resistance is solidified by a 960-hour salt spray protection per ASTM B117 standards. Additional technical specifications include an internal wetted surface area of approximately 91 cm² (14.1 in²), and a minimal internal leakage at shutoff, making it highly reliable for critical applications where leakage could pose significant issues. The NV10-20B-0-N weighs about 0.14 kg (0.30 lb), making it lightweight yet sturdy enough for both mobile and industrial applications.
