Bosch Rexroth AG R978909997 4WH6D52/12 Directional Spool Hydraulic Valve With Actuator

Features

Ports: 4 Main PortsType of Actuation: HydraulicConnections RadialSize: 6Spool Symbol: D

Description

Valves of type WP and WH are directional spool valves with fluid actuation. They control the start, stop, and direction of flow. A full array of spools are available for both the WH and WP operator. Features: Size 6 and 10. Direct operated directional spool valve. Porting pattern according to DIN 24340 form A (without locating hole). Porting pattern according to ISO 4401-03-02-0-05 and NFPA T3.5.1 R2-2002 D03 (with locating hole). Valves of type WP and WH are directional spool valves with fluid logics actuation. They control the start, stop and direction of a flow. The directional valves basically consist of housing (1), one or two actuation elements (2) (hydraulic, pneumatic actuation cylinder), control piston (3), and one or two return springs (4). The connections for control are arranged in a radial (model œWP, œWH) (5) or axial (model œWPZ, œWHZ) (6) way. In the de-energized condition, control piston (3) is held in the central position or in the initial position by the return springs (4) (except for impulse spool). The control spool (3) is moved to the required spool position by means of the actuation elements. SPECIFICATIONS: Ports: 4 Main Ports; Directional Valve; Type of Actuation: Hydraulic; Connections Radial; Size: 6; Spool Symbol: D; Component Series: 52; With Spring Return; Without Manual Override; Without Locating Hole; Clamping Length: 42mm (Standard); Seal Material: NBR Seals; Without Throttle Insert; Without Position Switch
