WMM Model 70 Series Manual Directional Control Valve: Technical Overview

Technical Specifications & Structural Features

• Operating Pressure Range: Supports 28–35 MPa (high-pressure variants) for heavy-load applications; low-pressure models (≤10 bar) for conventional hydraulic systems.

• Flow Characteristics: 70mm bore size models achieve flow rates up to 160 L/min (e.g., TRM20E series), compatible with parallel/series manifold configurations.

• Material & Manufacturing: Valve bodies crafted from cast steel or stainless steel with anti-corrosion surface treatments, suitable for high-dust/high-humidity environments. Precision casting and CNC machining ensure sealing integrity and durability.

• Operation Mechanism: Manual lever-actuated spool design with 3/2, 5/2 way configurations, featuring spring-return functionality for automatic mid-position reset.

• Interface Standards: Complies with ISO 1219 hydraulic symbol standards and Cetop3/5 manifold mounting, supporting pipe, flange, and other connection methods.

Application Scenarios & Functions

• Core Applications: Widely deployed in construction machinery (excavators, loaders, cranes), industrial equipment (forklift transmissions, hydraulic presses), and port logistics systems requiring precise fluid direction control.

• Functional Features: Enables circuit start/stop, flow reversal, and flow regulation (integrated throttling in select models). Supports manual emergency operation and integrates with electro-hydraulic hybrid control systems.
