The Hydraforce PC08-30-0-N-120 (5220002) is a pilot-operated hydraulic check valve, engineered for blocking or load-holding circuits in various hydraulic systems. This screw-in, cartridge-style valve facilitates free flow from port 2 to port 3 and normally blocks flow from port 3 to port 2. It permits flow in the reverse direction when pressure is applied at port 1, making it versatile for controlled hydraulic operations. The valve features a hardened seat which ensures long life and minimal leakage, enhancing system reliability. Optional configurations include a sealed piston and variable spring ranges, allowing customization to meet specific application requirements. Its compact design aids in easy integration into tight spaces without compromising performance. The PC08-30-0-N-120 operates efficiently within a pressure rating of up to 3500 psi (241 bar) and supports a wide range of operating temperatures depending on seal material—ranging from -40°C to +100°C with Buna N seals and up to +204°C with Viton seals. This model demonstrates minimal internal leakage rates, crucial for maintaining system efficiency and performance integrity. Furthermore, it is designed to work with mineral-based or synthetic hydraulic fluids, accommodating fluid viscosities from 7.4 to 420 cSt and tolerating maximum contamination levels as specified by ISO 4406 standards. The unit's weight is light at approximately 0.06 kg (0.14 lb), which supports its application in mobile and industrial environments without adding significant weight or bulk. Overall, the Hydraforce PC08-30-0-N-120 offers robust performance for hydraulic systems requiring reliable load holding and flow blocking capabilities combined with flexibility in installation and maintenance.
