The Hydraforce EV12-S34 (5282807) is a screw-in, cartridge-style, spool-type hydraulic directional element designed for precision and efficiency in controlling fluid flow in hydraulic systems. This model functions as a spring-biased blocking valve, which transitions to allow full flow from port 1 to port 2 when port 3 is vented, causing a pressure drop across the internal orifice that exceeds the bias spring value. With its multiple function application potential and industry-common cavity design, the EV12-S34 ensures compatibility and interchangeability with various systems. The valve features a low pressure drop and smooth shift transition, enhancing the operational efficiency and reliability of hydraulic circuits. It supports a maximum flow as indicated by performance graphs and can handle pressures up to 345 bar (5000 psi). The EV12-S34 operates within a temperature range of -40 to +100°C (-40 to +212°F) with standard Buna N seals, but it can also accommodate fluorocarbon seals for temperatures ranging from -26 to +204°C (-15 to +400°F) and polyurethane seals for temperatures from -54 to +107°C (-65 to +225°F). This model is suitable for use with mineral-based or synthetic hydraulic fluids that have lubricating properties, within a viscosity range of 7.4 to 420 cSt. Its maximum operating contamination level is rated at 20/18/14 per ISO 4406, ensuring clean operation even under demanding conditions. The EV12-S34 weighs approximately 0.28 kg (0.61 lb) and offers an internal wetted surface area of about 206 cm² (31.91 in²), making it compact yet robust enough for various applications without orientation restrictions during installation. Optional accessories include seal kits specific to system requirements and various housings compatible with standard valve bodies.
