Valve bank (directional seated valve) type BVH - 1

Mounted valves Valve bank (directional seated valve) type BVH A valve bank combines different valves for operating independent consumers. The valve bank type BVH comprises several directional seated valves that are connected in parallel. As cone valves the directional seated valves have zero leakage in the closed state. The valve sections are connected using banjo bolts. 2/2, 3/2, 4/2 and 4/3-way directional seated valves are available. Depending on the functional requirement, pressure reducing valves, pressure switches, check valves, restrictors or restrictor check valves are integrated into the valve section. The valve bank can be flange-mounted directly on compact hydraulic power packs or integrated into a pipe system via a piping block. Features and benefits: ■ Flexible expandability ■ Compact and lighter design (elimination of the base plates) Intended applications: ■ Auxiliary and clamping functions on machine tools and fixtures ■ Auxiliary and clamping functions on forming machine tools ■ Brake and rotor adjustment modules on wind turbines Version: Valve sections for pipe connection Actuation: Solenoid Design and order coding example BVH 11 M/CZ/35/M/R/2 - 8 - G24 Solenoid voltage 12V DC, 24V DC, 110V AC, 230V AC End plate ■ With tapped plugs at P, R ■ With accumulator port and drain valve Valve sections ■ With individual pressure reduction (parallel connection) ■ Additional elements: ■ Pressure-reducing valves ■ Orifice and/or check valve in P gallery ■ Orifice or restrictor check valve for A ■ Return pressure block in R gallery ■ Pressure switches for A Basic type Type BVH 11 for direct mounting onto connection blocks type A etc. (for compact hydraulic power packs type KA, MPN, HC, HK, HKF, HKL) © HAWE Hydraulik SE HAWE Products - 04-2017-5.2 1
