Manual eccentric hemisphere valve

Categories：

Eccentric Half Ball Valve

Supports customization. This product features an eccentric hemisphere valve structure design, equipped with a manual operation device to achieve reliable opening and closing and precise control of fluid pipelines. The friction between the valve seat and the valve plate is low, with excellent sealing performance, suitable for industrial pipeline systems in petroleum, chemical, electric power, metallurgy, and water treatment sectors.

Can be customized according to your needs.

Structural Features:

1. Straight-through Flow Channel Design
Feature: The internal flow channel of the valve is fully aligned with the pipeline, without any reduction or expansion in diameter, resulting in low fluid resistance and good fluid passage.

2. Eccentric Structure
Feature: The valve disc (ball) uses an eccentric design; when closed, the valve disc fits tightly with the valve seat, and when opened, the valve disc completely separates from the valve seat.

3. Single-seat Double-seal Structure
Feature: The single-seat double-seal design ensures the valve can achieve sealing under bidirectional conditions.

4. High Hardness Sealing Surface
Feature: The sealing surface is made of high hardness materials (such as stainless steel, hard alloy, etc.) and undergoes special treatment.

5. Low Opening and Closing Torque
Feature: The valve has low opening and closing torque, making operation easy. It consumes less energy, reducing the energy consumption of the drive device and lowering operating costs.

6. Top-mounted Structure
Feature: The valve's opening and closing components (such as valve disc, valve seat, etc.) can be removed and replaced from the top without dismantling the entire valve from the pipeline.

7. Self-cleaning Function

Feature: When the valve disc (ball) opens, the fluid flows evenly along the sealing surface, washing away deposits on the sealing surface.
Advantage: Reduces scaling on the sealing surface, extends the service life of the sealing surface, and maintains the valve's effective sealing performance.

8. Multiple Material Options Available
Feature: Components such as valve body, valve seat, and valve disc can be made from different materials according to various working conditions, such as ductile iron, carbon steel, etc.

Advantages:
Strong adaptability: Suitable for various media and working conditions, meeting different user needs.
Economical: Users can select appropriate materials based on actual needs to optimize costs.
