The Hydraforce PD12-45-0-NS-170 (5265826) is a high-performance, screw-in, cartridge style, pilot-operated, spool type hydraulic directional valve designed for advanced fluid control applications. This valve operates by allowing flow from port 2 to 3 bidirectionally in its neutral position. Upon receiving a remote pilot signal at port 1, the spool shifts to block the flow between these ports. The design includes a spring chamber vented to port 4, which is internally o-ring sealed from the cartridge's flow paths. Notably, any pressure on port 4 directly influences the pilot pressure required on a 1:1 basis and must be considered alongside the bias spring value. Constructed for durability and long-term use, the PD12-45-0-NS-170 features a hardened spool and cage. Its design is optimized for both efficiency and cost-effectiveness in its cavity configuration. The valve operates effectively within a pressure rating of up to 241 bar (3500 psi) and supports various fluid temperatures ranging from -40°C to +100°C with standard Buna N seals, making it versatile across different operating environments. Its compatibility with mineral-based or synthetic hydraulic fluids that possess lubricating properties ensures broad usability. Additionally, this model accommodates fluid viscosities ranging from 7.4 to 420 cSt and can handle maximum operating contamination levels as specified by ISO 4406 standards. For installation, the PD12-45-0-NS-170 utilizes a VC124 cavity and requires a torque of about 44.7 to 50.2 Nm for cartridge installation. There are no orientation restrictions in mounting this valve, allowing flexibility in system design. Accessories such as seal kits (SK124XMMM) tailored to specific seal options are available along with comprehensive installation instructions and compatible housings for complete setup solutions.
