The Hydraforce PC08-30-0-N-XXX (5220000) is a screw-in, cartridge-style, pilot-operated hydraulic check valve designed primarily for blocking or load holding circuits in hydraulic systems. It facilitates free flow from port 2 to port 3 and generally blocks flow from port 3 to port 2. However, flow from port 3 to port 2 is permitted when pressure is applied at port 1. This model features a hardened seat that ensures long life and minimal leakage, enhancing the valve’s reliability and performance in demanding applications. The PC08-30-0-N-XXX offers optional components such as a sealed piston and various spring ranges, allowing customization to meet specific system requirements. Its compact size allows for easy integration into tight spaces within hydraulic circuits. The valve operates effectively within a pressure rating of up to 3500 psi (241 bar) and handles a wide range of operating temperatures depending on the seal material—ranging from -40°C to +100°C with Buna N seals and up to +204°C with Viton seals. Regarding fluid compatibility, it works with mineral-based or synthetic hydraulic fluids that have lubricating properties, supporting fluid viscosity ranges from 7.4 to 420 cSt. The maximum internal leakage specifications ensure efficient operation, with values like 0.1 ml/min between ports 3 and 2 under typical conditions. For installation, the valve fits into VC083 cavities with an installation torque between 25.8 to 28.5 Nm. Overall, the Hydraforce PC08-30-0-N-XXX is engineered for versatility and durability in various hydraulic applications requiring precise flow control and load holding capabilities.
