SYMBOL: | DESCRIPTION A screw-in, cartridge-style, spool-type, hydraulic directional valve which operates by pressure-to-shift spring return. It is normally used to release a spring-applied brake whenever hydraulic power is directed to move a load. OPERATION In neutral, the BV10-40 allows flow from 2 to 3. When the pressure differential between the 1 and 4 ports exceeds approximay 5.5 bar (80 psi), the spool has moved far enough to close 2 to 3 flow, while opening the higher pressure of 1 or 4 to 2. FEATURES • Hardened spool and cage for long life. • Industry common cavity. RATINGS Operating Pressure: 240 bar (3500 psi) Proof Pressure: 390 bar (5700 psi) Flow: up to 7.5 lpm (2 gpm) Maximum Internal Leakage at 207 bar (3000 psi): 164 cc/minute (10 cu. in./minute) Differential Pressure Required: (1 > 4, 4 > 1) to Shift to Close 2 to 3 / Open 1 or 4 to 2: 5.5 bar (80 psi) Temperature: -40° to 100°C (-40° to 212°F) with Buna seals; -26° to 204°C (-15° to 400°F) with fluorocarbon seals. Filtration: See page 9.010.1 Fluids: Mineral-based or synthetics with lubricating properties at viscosities of 7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1 Installation: No restrictions; See page 9.020.1 Cavity: VC10-4; See page 9.110.1_4w Cavity Tool: CT10-4xx; See page 8.600.1 Seal Kit: SK10-4x-TBT; See page 8.650.1 |
