Hawei BWH1A-3/4-AR2R2R2R2-1-G24 directional valve

HAWE BWH1A-3/4-AR2R2R2R2-1-G24 is a globe type directional valve group belonging to the BWH1 series, mainly used for controlling the on/off and flow direction of oil circuits in hydraulic systems.

This model code contains key information such as the structure, specifications, function, and driving mode of the valve. The following is a detailed parameter analysis:

1. Model code analysis

• Brand and Series

• HAWE: German Hawei brand.

• BWH1A: Belongs to the BWH1 series globe directional valve. This series adopts a conical valve core, which seals without leakage when closed.

• Specification and diameter

• 3/4: Indicates that the interface size or diameter of the valve is 3/4 inch.

• Valve core function

• As a valve group, it is usually composed of multiple 2/2 (two position two-way) or 3/2 (three position two-way) valves combined.

• A "and" R "respectively represent different working oil port functions.

• This model is specifically configured with 4 valve positions (because there are 4 sets of "R2"), with complex control logic, commonly used to control multiple actuators or implement specific sequential actions.

• AR2R2R2R2: This section defines the functionality of multiple directional valves.

• Design and Accessories

• 1-1: Usually represents the structural form of the valve group, the type of connecting block, or whether it includes specific one-way valves and other configurations.

• Drive Type

• G24: Refers to electromagnetic drive, with a power supply of 24V DC.

2. Core Features

• No leakage: As a globe type directional valve, its conical seat structure ensures that there will be no hydraulic oil leakage when in the closed state, which is very important for working conditions that require long-term pressure maintenance.

• Modular combination: The BWH1 valve group can be combined like building blocks, with multiple valves, front blocks, and tailboards connected in series through connecting rods, allowing for up to 10 valves to be combined.

• High integration: The valve group integrates pressure oil circuit (P) and return oil circuit (R) inside, and can integrate overflow valve or pressure relay on the bottom plate to reduce pipeline connections.

3. Typical application scenarios

Due to its compact structure, leak free and high-pressure resistance, this valve group is commonly used in:

• Machine tools (metal cutting and non cutting)

• Agricultural and forestry machinery

• Mining and engineering machinery

• Rubber and plastic machinery
