The Hydraforce HSV12-28-0-U-24EG (5542152) is a high-performance solenoid cartridge valve, meticulously designed for hydraulic applications requiring robust load holding or blocking capabilities with minimal internal leakage in both directions. This bidirectional, poppet-type, normally closed valve is engineered to operate efficiently under high-pressure conditions up to 350 bar (5075 psi) and can handle a maximum flow rate of 113.6 liters per minute (30 gpm). The valve showcases exceptional durability and reliability with its hardened seat ensuring long life and low leakage, and it can withstand proof pressures up to 690 bar (10000 psi) and burst pressures up to 1380 bar (20000 psi). The HSV12-28-0-U-24EG features an innovative manual override operation. In normal conditions when deenergized, the manual override pin must be seated in the lower detent groove. For manual operation, the operator can push down on the knob, rotate it 180 degrees in either direction, or pull on the knob for increased flow during emergencies—though it is not intended for continuous-duty operations. The unit’s versatility is further enhanced by its compatibility with various seal materials suitable for different temperature ranges: Buna N seals operate between -40°C to +100°C (-40°F to +212°F), fluorocarbon seals from -26°C to +204°C (-15°F to +400°F), and urethane seals from -54°C to +107°C (-65°F to +225°F). Additional features include optional waterproof E-Coils rated up to IP69K, efficient wet-armature construction, voltage interchangeable cartridges, and a unitized molded coil design. The valve’s construction adheres strictly to NFPA specification T2.6.1 standards with a verification level of 90% and an assurance level of 99%, ensuring top quality and performance in demanding hydraulic systems.
