The Hydraforce RV12-26A-0-V-04 (5623001) is a high-performance, screw-in, cartridge-style pilot-operated relief valve designed for demanding hydraulic circuits. This two-stage spool type relief valve serves as a pressure-limiting device, offering fast response and low hysteresis. It effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to dislodge the pilot relief, allowing the main stage to open and facilitate flow between the ports. Notably, this valve is unsuitable for cross-over relief applications. Key features include non-backout adjustments that prevent springs from solidifying, a hardened spool and cage for enhanced durability, and optional spring ranges up to 240 bar (3500 psi). The valve ensures rapid and smooth responses to pressure surges within its cost-effective cavity. The RV12-26A-0-V-04 handles pressure ratings of up to 241.3 bar (3500 psi) at port 1 and 103.4 bar (1500 psi) at port 2, with proof pressure reaching 689.5 bar (10000 psi) and burst pressure at an impressive 1379.0 bar (20000 psi). It defines crack pressure with flow evident at 7.6 lpm (2 gpm). The flow rating peaks at 170.3 lpm (45 gpm) under maximum pressure conditions, while maximum internal leakage is capped at 197 ml/min (12 in\u00b3/min) at port 2 when set nominally. Operating fluid temperature ranges vary with seal types: -40 to 100 \u00b0C (-40 to 212 \u00b0F) for Buna N seals, -26 to 204 \u00b0C (-15 to 400 \u00b0F) for fluorocarbon seals, and -54 to 107 \u00b0C (-65 to 225 \u00b0F) for polyurethane seals. The valve withstands storage and ambient temperatures from -40 to 70 \u00b0C (-40 to 160 \u00b0F), offers corrosion protection up to a remarkable 960 hours of salt spray per ASTM B117 standards, supports fluid viscosities from 7.4 to 420 cSt, and maintains an operating contamination level of ISO cleanliness code of up to18/16/13 per ISO4406 standards. Installation specifications include compatibility with VC12-2 cavities requiring cartridge installation torque between specified ranges depending on plug styles used; orientation restrictions are absent making it versatile across different setups while seal kits like SK12-2X-B offer additional customization options according sealing preferences required by specific applications where this robust hydraulic component finds utility effectively managing pressures reliably over extended operational periods ensuring system safety against overpressure risks inherent within complex hydraulic systems prevalent across varied domains utilizing such critical components engineered precisely meeting rigorous demands efficiently without compromise on quality performance longevity even under challenging conditions encountered routinely across diverse environments globally today!
