The Hydraforce NV12-20B-0-N (5421100) 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 size from fully closed to fully open with a counterclockwise adjustment rotation, allowing for linear and positive shutoff adjustments. The design ensures that adjustments cannot be backed out unintentionally and can be securely locked down once the desired setting is achieved. Constructed with hardened parts, the NV12-20B-0-N offers enhanced durability and longevity. It features an aluminum knob option for ease of use and aesthetic preference. The valve is compatible with various seal materials including Buna N, Fluorocarbon, HNBR, and Polyurethane, to suit different operating temperatures ranging from -40°C to +300°F depending on the seal type used. The NV12-20B-0-N can withstand pressures up to 3500 psi with a proof pressure of 5000 psi and a burst pressure of 13000 psi. Its maximum internal leakage is minimal at 3 drops per minute at shutoff. Suitable for use with mineral-based or synthetic hydraulic fluids with lubricating properties, it supports fluid viscosity ranges from 7.4 to 420 cSt and operates effectively within contamination levels specified by ISO4406 standards. This valve's design includes no orientation restrictions during installation, making it versatile for various system configurations. It fits into VC122 or HNV122 cavities and requires an installation torque between 90 to 100 ft-lb. The NV12-20B-0-N weighs approximately 0.50 lb and offers an internal wetted surface area of 14.6 square inches, ensuring efficient operation within hydraulic circuits.
