Product details

I. Definition

TheQJF Series Accumulator Ball Valvesare specialized valves designed to control the charging and discharging of hydraulic accumulators. Typically installed between the accumulator and the hydraulic circuit, they regulate fluid flow by rotating a spherical disc to isolate or connect the accumulator to the system.

------

II. Functions

1. Isolation: Enables safe accumulator maintenance or replacement by shutting off fluid flow, preventing hydraulic leaks.

2. Charge/Discharge Control: Manages accumulator pressurization and depressurization to stabilize system pressure.

3. Protection: Works with accumulators to absorb pressure surges, safeguarding system components from damage.

------

III. Applications

1. Construction Machinery: Used in excavators, loaders, and rollers for pressure maintenance and energy recovery in hydraulic systems.

2. Industrial Equipment: Applied in injection molding machines, die-casting machines, and machine tools requiring stable pressure or shock absorption.

3. Energy Sector: Utilized in wind turbines and oil drilling rigs for energy storage and load balancing.

------

IV. Structural Features

1. Precision Ball Design: High-accuracy spherical disc paired with valve seats ensures low leakage and superior sealing.

2. Durable Materials: Forged steel or stainless steel valve bodies resist high pressure and corrosion, adapting to harsh environments.

3. Easy Operation: 90° rotation via a handle or actuator enables quick opening/closing.

4. Compact Design: Lightweight and space-saving for simplified installation and maintenance.

------

V. Selection Guidelines

1. Pressure Rating: Choose a valve with a pressure rating exceeding the system’s maximum operating pressure for safety margins.

2. Port Size Matching: Ensure the valve’s port size aligns with the accumulator interface and hydraulic piping to avoid flow restrictions.

3. Material Suitability: Select valve body materials (e.g., stainless steel for corrosive fluids) based on hydraulic fluid type and operating conditions.

4. Sealing Performance: Prioritize valves with bidirectional sealing to prevent reverse fluid leakage.
