The Hydraforce TS38-21B-0-N-00 (5122819) is a direct-acting, spool-type, proportional pressure relieving valve designed to regulate pressure inversely proportional to the input electrical current. It effectively blocks flow from port 1 to port 2 until sufficient pressure overcomes the preset spring force at port 1. In the absence of electrical current, the valve relieves at maximum range, and applying current reduces the spring force, thereby lowering the valve setting. The valve features standard 12 and 24 volt coils with optional waterproof E-Coils rated up to IP69K for enhanced durability. It boasts hardened parts for extended life and fits into an industry-common cavity VC08-2. The TS38-21B can handle pressures up to 248.2 bar (3600 psi) at port 1 and proof pressures of up to 344.7 bar (5000 psi). Its burst pressure capability reaches an impressive 758.4 bar (11000 psi). The adjustable pressure range varies from 6.9 to 241.3 bar (100 to 3500 psi), catering to diverse operational needs. With a flow rating of 1.1 lpm (0.3 gpm), it maintains low hysteresis percentages across different settings, ensuring precision in control applications. The operating fluid temperature ranges from -40 to 100 \u00b0C with buna N seals and extends further with other seal types, making it adaptable for various environments. Additionally, it offers robust corrosion protection withstanding up to 960 hours of salt spray per ASTM B117 standards and supports fluids within a viscosity range of 7.4 to 420 cSt while maintaining a maximum operating contamination level of ISO 4406 class 18/16/13. Its compact design weighs just 0.16 kg and requires specific installation torques for optimal performance without orientation restrictions, offering flexibility in installation setups.
