The Hydraforce NV12-20B-12T-N (5421180) 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 valve is crafted to ensure durability and reliability with features like hardened parts and an option for an aluminum knob. It is engineered to prevent adjustments from backing out, thereby maintaining desired settings securely. The NV12-20B-12T-N supports a pressure rating up to 241 bar (3500 psi), with proof pressure at 345 bar (5000 psi) and burst pressure reaching 896 bar (13000 psi). It accommodates a wide range of operating fluid temperatures depending on the seal material used—ranging from -40°C to +204°C. The valve is compatible with mineral-based or synthetic hydraulic fluids with lubricating properties and operates efficiently within a fluid viscosity range of 7.4 to 420 cSt. This model is versatile in terms of installation, fitting into VC122 or HNV122 cavities without orientation restrictions and requiring a cartridge installation torque between 122 to 136 Nm. Weighing approximately 0.23 kg, it has an internal wetted surface area of about 94 cm². The NV12-20B-12T-N can be used with various seal kits including Buna N, Fluorocarbon, HNBR, and Polyurethane options to suit different environmental conditions and applications. This makes it an ideal choice for a broad spectrum of hydraulic applications demanding robust performance and precise flow control.
