The Hydraforce EV12-S34T-0-N-240 (5282820) is a screw-in, cartridge-style, spool-type, hydraulic directional element designed for versatile hydraulic system applications. This model operates as a spring-biased blocking valve that transitions to allow full flow from port 1 to port 2 only when port 3 is adequately vented to create a pressure drop across the internal orifice that exceeds the bias spring value. This precise operation ensures smooth shift transitions and a low pressure drop, enhancing overall system efficiency. The unit is engineered for multiple function applications and can be adapted to various hydraulic tasks thanks to its industry-common cavity design. It offers compatibility with mineral-based or synthetic hydraulic fluids with lubricating properties within a fluid viscosity range of 7.4 to 420 cSt. The EV12-S34T-0-N-240 can handle operating fluid temperatures ranging 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. Structurally, the valve features optional tall cap versions for higher bias spring values and has an internal wetted surface area of 253 cm² in the EV12S34T model variant. It fits into VC12S3 cavity types without any orientation restrictions during installation and supports a maximum operating contamination level of 20/18/14 per ISO 4406. The directional element's robust construction allows it to operate efficiently under pressures up to 345 bar (5000 psi), supporting maximum internal leakage standards of 164 ml/min at 207 bar (3000 psi). This makes the Hydraforce EV12-S34T-0-N-240 an ideal choice for demanding hydraulic applications requiring precise control and reliability.
