Опис производа

Strategic cooperation between the Chinese and German governments from 1979, Huade has incorporated cutting-edge technology from Rexroth. Huade® WE 4 directional spool valve is an affordable alternative to the same model offered by Rexroth. Huade puts great stress on the quality. Huade has a strict testing system to ensure that every directional valve has superior performance. The solenoid valve series has passed CE certification. Huade® hydraulic valves are widely used in engineering and construction machinery, metallurgy, machine tools, environmental protection, shipbuilding, aerospace, rail transit, petroleum and petrochemical, military industry and other fields. It is a reliable national brand in China.

Product Feature And Application of Directional Control Valve WE 4 for Rexroth

Features:

▶ Directional valves of type WE 4 are solenoid operated directional spool valves

▶ Wet pin solenoids of direct or alternating current

▶ Porting pattern to ISO 4401 and CETOP - RP 121H

Application:

Directional valves of type WE 4 are solenoid operated directional spool valves. They control the start, stop and direction of a fluid.

Functions,Section and Symbols of the Directional Control Valve WE 4 for Rexroth

These directional valves basically consist of the housing(1), one or two solenoids (2), the control spool(3), and one or two return springs(4).

The control spool (3) is held by the return spring (4) in the central or in the initial position (except for detented spools). The control spool(3) is actuated via wet pin solenoids (2). In the energized condition. The force of the solenoid(2) acts via the plunger (5) on the control spool (3) and shifts the same from its rest position to the desired end position. Thus, the required flow pattern from P to A and B to Tor P to B and A to T is selected. When the solenoid(2) is de-energized, the control spool (3) is returned to its neutral

This version is a directional valve with 2 switching positions and position by the return spring (4). A covered manual override is provided so that the control spool (3)can be operated without

energizing the solenoid.
