YJZQ Series High-Pressure Ball Valve

I. Product Introduction

The YJZQ Series High-Pressure Ball Valve is a 2-way threaded ball valve designed for high-pressure hydraulic systems. The valve features a floating ball sealing structure, forged steel body, and internal threaded connections, providing reliable sealing and convenient operation for industrial high-pressure fluid pipeline applications.

II. Working Principle

The ball valve uses a 90° rotary operation to control medium flow. The floating ball is pressed against the downstream seal seat by medium pressure, achieving self-sealing under high-pressure conditions. The full bore design ensures minimal flow resistance and smooth medium transfer.

III. Structural Features

1. Internal threaded connection, convenient for pipeline installation and disassembly;

2. Floating ball self-pressure sealing, medium pressure assists sealing, reliable leak-free performance;

3. Forged steel body with high structural strength, pressure and impact resistant;

4. 90° rotary operation with small torque, quick and labor-saving opening/closing;

5. Full bore design, smooth medium flow with minimal pressure loss;

6. Surface anti-corrosion treatment, suitable for various industrial environments.

IV. Core Applications

Widely used in hydraulic machinery, hydraulic control systems, industrial fluid pipelines, and energy storage hydraulic circuits, for high-pressure pipeline medium on-off control and pipeline isolation in machine tools, construction machinery, and industrial equipment.

V. Usage Precautions

1. Select the appropriate specification based on pipeline pressure rating and medium type;

2. Ensure threaded connections are clean, use appropriate sealing tape or compound;

3. Operate with uniform force, do not use tools to force the valve beyond its design limits;

4. Regularly inspect sealing performance, replace worn seals as needed;

5. Clean the valve cavity before installation to prevent impurity damage to the ball surface.
