The Hydraforce NV12-20C-0-N (5421200) is a high-performance, screw-in, cartridge-style needle valve designed for precise flow restriction in hydraulic systems. This variable orifice hydraulic flow restrictor valve allows for linear adjustment from fully closed to fully open with a counterclockwise rotation, ensuring easy and reliable control over fluid flow. The valve's construction includes features that prevent adjustments from being backed out unintentionally, with an option to lock down desired settings securely. Engineered for durability, the NV12-20C-0-N incorporates hardened parts to extend its operational life and is equipped with an aluminum knob for enhanced usability. It offers a positive shutoff capability and is designed to fit into VC122 or HNV122 cavities without any orientation restrictions. The unit weighs approximately 0.23 kg and has an internal wetted surface area of 94 cm². In terms of performance, the valve operates efficiently within a temperature range of -40°C to +100°C when using Buna N seals, with other seal options available for varying temperature conditions up to 204°C. It supports mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. The NV12-20C-0-N maintains its integrity under high pressures up to 241 bar (3500 psi) and is proof-tested up to 345 bar (5000 psi), with a burst pressure rating of 896 bar (13000 psi). This needle valve is suitable for applications requiring precise control over fluid handling in hydraulic systems across various sectors, supported by accessories like seal kits and housing options tailored for specific installation needs.
