The Hydraforce SV16-21-16T-N-12DL (5061931) is a solenoid-operated, 2-way, normally open, poppet-type hydraulic cartridge valve. It is designed to serve as a load-holding or blocking valve in scenarios that demand low internal leakage. When de-energized, the SV16-21 configuration allows flow from port 2 to port 1, while severely restricting flow in the reverse direction. Upon energization, it closes the port 2 to port 1 path and functions as a check valve permitting flow from port 1 to port 2 after overcoming the solenoid force of 50 to 100 psi (3.4 to 6.9 bar). The valve features a continuous-duty rated coil and a hardened seat for durability and minimal leakage. It offers optional coil voltages and terminations along with an efficient wet-armature construction that supports voltage interchangeability among cartridges. The unitized, molded coil design includes a manual override option and optional waterproof E-Coils rated up to IP69K for enhanced environmental protection. The SV16-21 model is pressure-rated at 207 bar (3000 psi) with static pressure handling up to 250 bar (3650 psi) based on one million cycles. It has proof pressure capabilities of up to 345 bar (5000 psi) and burst pressure resistance reaching 965 bar (14000 psi). Maximum internal leakage stands at three drops per minute at full pressure rating. The operating fluid temperature ranges from -40\u00b0C to 100\u00b0C (-40\u00b0F to 212\u00b0F) with buna N seals, extending up to -26\u00b0C to 204\u00b0C (-15\u00b0F to 400\u00b0F) using viton seals. Compatible with mineral-based or synthetic hydraulic fluids with lubricating properties, it supports fluid viscosity ranging from 7.4 cSt to 420 cSt and maintains an ISO cleanliness level of 20/18/14 per ISO standards. Installation requires VC16-2 cavities with specified torque values for both cartridge installation and coil nut applications.
