1. Product Overview
TheOne-Way Throttle Valve MG10is a hydraulic valve that combines throttling and check functions, designed for applications requiring precise flow control while preventing reverse flow of the medium. This valve enables stepless flow adjustment by rotating an adjustable sleeve and allows free reverse flow to prevent system pressure fluctuations or equipment damage.

2. Technical Characteristics
Functional Design
• Throttling Function: Flow rate is adjusted steplessly by rotating the adjustable sleeve to modify the throttle cross-section.
• Check Function: Throttles during forward flow while permitting unrestricted reverse flow to prevent backflow.
• Self-Cleaning Design: Fluid flow through the annular gap removes contaminants, reducing the risk of valve core jamming.
Performance Parameters
• Pressure Range: Up to315 bar, suitable for high-pressure hydraulic systems.
• Flow Range: Maximum flow rate of400 L/min(varies by model and configuration).
• Temperature Range: Typically applicable in environments from-20°C to +80°C(may vary based on sealing materials).
• Connection Type: Threaded connection (e.g.,G 1 ISO 228-1 standard) for direct integration into pipelines.
Materials and Structure
• Valve Body Material: High-pressure, corrosion-resistant alloy steel or tungsten carbide hard alloy for long-term reliability.
• Sealing Design: Wear-resistant sealing materials (e.g.,VFPM seals) prevent leakage.
• Adjustment Mechanism: Flow is adjusted via rotational markings on the sleeve, ensuring precision and ease of operation.

3. Applications
Construction Machinery
• Controls cylinder speeds in excavators, loaders, and other equipment by regulating actuator movement via throttling.
• Prevents hydraulic oil backflow, protecting pumps and other components from damage.
Industrial Equipment
• Precisely regulates motor speeds or pilot valve response times in injection molding machines, machine tools, and hydraulic fixtures.
• Suitable for bidirectional flow adjustment scenarios, such as clamping/releasing operations.
Energy Sector
• Stabilizes flow in hydraulic systems of wind turbines and hydroelectric equipment to maintain operational efficiency.
• Prevents backflow-induced pressure fluctuations, ensuring safe system operation.

4. Selection and Installation Guidelines
Selection Principles
• Pressure and Flow Matching: Choose a valve with appropriate pressure ratings and flow ranges to align with system requirements.
• Media Compatibility: Verify material compatibility with hydraulic fluids or other media to avoid corrosion or wear.
• Temperature Adaptability: Account for ambient temperature effects on sealing materials and fluid viscosity.
Installation Precautions
• Pipeline Cleaning: Thoroughly clean pipelines before installation to prevent contaminants from causing wear or jamming.
• Correct Orientation: Ensure installation direction matches media flow (indicated by arrows on the valve body).
• Accessibility: Select an easily operable and adjustable location for maintenance convenience.
• Shut-Off Valves: Install upstream/downstream shut-off valves to isolate the system during servicing.
