The Hydraforce DC08-40-0-N-135 (5230006) is a dual pilot operated check valve, specifically designed for use in blocking or load holding circuits that utilize general purpose hydraulic fluids. This model stands out due to its hardened seat which ensures long life and minimal leakage, contributing to its reliability and efficiency in various applications. The valve operates effectively with a compact size that facilitates easy integration into existing hydraulic systems without requiring extensive modifications. The DC08-40-0-N-135 supports a maximum flow rate of 19 liters per minute (5 gallons per minute) and exhibits maximum internal leakage of merely 0.25 ml/min at 207 bar (3500 psi), highlighting its precision and effectiveness in fluid control. It is engineered to handle a substantial pressure rating of up to 241 bar (3500 psi), with proof pressure reaching up to 350 bar (5075 psi) and an impressive burst pressure of 966 bar (14000 psi). The pilot ratio for this valve is set at 3:1, ensuring responsive operation under varying conditions. Temperature tolerance of the DC08-40-0-N-135 varies with the type of seal used; it ranges from -40°C to +100°C with Buna N seals, -26°C to +204°C with fluorocarbon seals, and -54°C to +107°C with polyurethane seals. This flexibility allows the valve to operate efficiently across different environmental conditions and fluid temperatures. Additional features include corrosion protection that withstands up to 960 hours of salt spray per ASTM B117 standards, making it suitable for challenging operating environments. The valve's design also accommodates various sealing options such as Buna N, fluorocarbon, polyurethane, and urethane, ensuring compatibility with different system requirements and enhancing its utility across diverse hydraulic applications.
