The Hydraforce NV12-20A-0-N (5421000) 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 and controlled adjustments. The valve's design ensures that adjustments cannot be backed out unintentionally, and desired settings can be securely locked down. Constructed with hardened parts, the NV12-20A-0-N promises long service life and durability under harsh conditions. It includes an aluminum knob option for enhanced usability and offers positive shutoff capabilities to prevent fluid leakage when closed. The valve operates effectively within a pressure range up to 3500 psi, with proof pressure at 5000 psi and burst pressure reaching up to 13000 psi. Suitable for use with mineral-based or synthetic hydraulic fluids that have lubricating properties, it supports a fluid viscosity range from 7.4 to 420 cSt and can handle maximum operating contamination levels as specified by ISO4406: 18/16/13. This model is compatible with various seal materials including Buna N, Fluorocarbon, HNBR, and Polyurethane to accommodate different temperature and environmental conditions ranging from -40°C to +400°F depending on the seal type. The NV12-20A-0-N is designed for easy installation in standard VC122 or HNV122 cavities without orientation restrictions and requires an installation torque between 90 to 100 ft-lb. Weighing approximately 0.50 lbs., it integrates seamlessly into existing systems providing reliable performance and efficient flow control in diverse hydraulic applications.
