KHB (BKH), KHM (MKH) Series High-Pressure Ball Valve

I. Product Introduction

This product is a 2-way high-pressure ball valve available in KHB (BKH) and KHM (MKH) series, suitable for high-pressure hydraulic pipeline systems. The valve adopts a floating ball sealing structure with 90° rotary operation, providing reliable sealing and convenient operation. The valve body is made of high-quality forged steel with surface anti-corrosion treatment, suitable for long-term use in various industrial conditions.

II. Working Principle

The ball valve uses the valve stem to drive the ball, rotating around the valve stem axis. By rotating the ball 90°, the internal flow port aligns with or blocks the pipeline, achieving medium conduction or cut-off. The floating ball design uses medium pressure to press the ball against the downstream seal seat, enhancing the sealing effect under high-pressure conditions.

III. Connection Methods

1. Threaded connection: Suitable for small to medium diameter pipelines with convenient installation;

2. Flange connection: Suitable for medium to high pressure and large diameter pipelines;

3. Plate connection: Suitable for hydraulic integrated valve block embedded installation.

IV. Product Features

1. Available in KHB (BKH) and KHM (MKH) series with clear selection categories;

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

3. 90° rotary operation with small torque, convenient and labor-saving;

4. Full bore design with minimal flow resistance, suitable for high-pressure fluid transfer;

5. Forged steel body with anti-corrosion surface treatment, durable and wear-resistant;

6. Multiple connection options, versatile for different pipeline installation requirements.

V. Core Applications

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

VI. Usage Precautions

1. Select the appropriate series based on pipeline pressure rating and connection requirements;

2. Ensure connection interfaces are clean and free of impurities, tighten evenly to prevent leakage;

3. Operate the valve with uniform force; do not use excessive force to avoid ball or seal damage;

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

5. Clean the valve cavity before installation to prevent impurities from entering and damaging the ball surface.
