Shop Argo Hytos ST2C1A Needle Restrictor Cartridge Valves

The Argo Hytos ST2C1A Needle Restrictor valve is a hydraulic flow control device designed to regulate the flow of fluid in hydraulic systems. It comes in a cartridge form that can be easily screwed into compatible hydraulic systems via a common C-8-2 Cavity. With a maximum flow capacity of 5GPM and a maximum pressure rating of 4600psi, it effectively controls fluid flow within these parameters. The valve features precision-engineered hardened components, allowing for fine-tuned adjustments with low torque requirements. Additionally, it offers options for reverse flow check functionality, ensuring fluid only moves in the desired direction. The valve can be adjusted using either an allen key or hand screw, with settings capable of being securely locked down for operational stability. Its standard zinc coating provides extended protection against corrosion, ensuring long-lasting performance even in harsh environments.
