The Hydraforce HSV12-28-12HT-U-12ER (5542246) is a high-performance hydraulic cartridge valve specifically designed for applications requiring a reliable method to hold or block loads with minimal internal leakage in both directions. This 2-way, piloted, poppet-type, normally closed valve operates bidirectionally and is engineered to be screwed into place, providing a secure and stable installation. When energized, the HSV12-28-12HT-U-12ER permits flow in both directions, while it blocks flow when deenergized. A key feature of this model is its manual override function. In normal operation with the valve deenergized, the manual override pin is seated in the lower detent groove. For manual shifting, an operator can push down on the knob and rotate it 180 degrees in either direction. Pulling on the knob when the manual override is actuated allows for increased flow. It's important to note that this manual override is intended primarily for emergency use rather than continuous-duty operation. The valve boasts a hardened seat ensuring long life and low leakage alongside optional coil voltages and terminations that enhance its adaptability across different systems. Its efficient wet-armature construction along with voltage interchangeable cartridges ensure operational efficiency and flexibility. The unit also features a unitized, molded coil design and offers an optional waterproof E-Coils rated up to IP69K for enhanced durability against harsh conditions. Furthermore, this model has been rigorously tested according to NFPA specification T2.6.1 ensuring reliability with a verification level of 90% and an assurance level of 99%. The solenoid tubes and coils are rated for 960 hours of salt spray, underscoring their robustness in corrosive environments. With pressure ratings up to 420 bar (6090 psi), proof pressure at 690 bar (10000 psi), and burst pressure at 1380 bar (20000 psi), along with other specifications like cycle life of one million cycles and various temperature ratings depending on seal material used, this valve is built for heavy-duty applications while maintaining precise control over hydraulic flows.
