The Hydraforce SP16-20Y-16T-N-24DG (5062061) is a solenoid-operated, 2-port, normally closed, poppet-type proportional hydraulic cartridge valve. It is specifically engineered for low leakage blocking and load-holding applications. In its default de-energized state, the SP16-20 functions as a check valve, permitting flow from port 1 to port 2 while obstructing flow in the reverse direction from port 2 to port 1. Upon energization, the poppet lifts to enable flow from port 2 to port 1, with significant restriction on the reverse flow path. This valve features a continuous-duty rated coil and efficient wet-armature construction. Optional manual override and waterproof E-Coils rated up to IP69K enhance its versatility and durability in various environments. The SP16-20 operates optimally under pressure ratings of up to 250 bar (3625 psi), with proof pressure at 344 bar (5000 psi) and burst pressure at an impressive 779 bar (11300 psi). It can handle a flow rate of up to 227.4 lpm (60 gpm) based on a pressure drop of 34.4 bar (500 psi). The valve maintains maximum internal leakage of only five drops per minute at rated pressure and exhibits hysteresis percentages of up to 5% for currents up to 60% of imax and up to 10% from there onwards. Designed for robustness in diverse temperature ranges, it accommodates operating fluid temperatures between -40\u00b0C (-40\u00b0F) and +204\u00b0C (+400\u00b0F) depending on seal type used\u2014buna N, fluorocarbon, or polyurethane seals are available. The unit's corrosion protection is affirmed by its ability to withstand salt spray for up to 960 hours per ASTM B117 standards. With a fluid viscosity range of 7.4 to 420 cSt and an ISO contamination level rating of 20/18/14, this valve is suitable for use with mineral-based or synthetic hydraulic fluids with lubricating properties.
