The Hydraforce RV16-26A-16T-N-35/18 (Material Number: 5623572.18) is a screw-in, cartridge-style, pilot-operated relief valve designed for demanding hydraulic circuits requiring fast response and low hysteresis. It operates as a pressure-limiting device by blocking flow from port 1 to port 2 until sufficient pressure at port 1 forces the piloting relief off its seat, allowing the main spool to shift and open the passage. This valve is not suitable for cross-over relief applications. The RV16-26A features a pressure rating of up to 275.8 bar (4000 psi), with proof and burst pressures of 620.5 bar (9000 psi) and 1275.5 bar (18500 psi), respectively. Its crack pressure is defined at a flow rate of 7.6 lpm (2 gpm), with a reseat pressure nominally at 90% of crack pressure. The relief pressure range extends from 27.6 to 344.7 bar (140 to 3500 psi). The valve supports a flow rating of up to 302.8 lpm (80 gpm) at maximum pressure, with internal leakage rates varying based on the pressure setting: up to 114.7 ml/min below and up to 491.6 ml/min above a setting of approximately 137.9 bar (2000 psi). Operating fluid temperatures vary depending on seal material, ranging from -40\u00b0C (-40\u00b0F) with Buna N seals to -54\u00b0C (-65\u00b0F) with polyurethane seals. Installation requires adherence to specific torque values for both cartridge installation and H-style plug, with no orientation restrictions noted. The unit's weight varies by configuration from approximately 0.58 kg to 0.71 kg, while its internal wetted surface area ranges between 273 cm\u00b2 and 308 cm\u00b2 depending on the model specifics. The recommended cavity size for installation is VC16-2, in line with its design specifications as a pilot-operated relief valve under U.S Patent #7,137,406.
