Cast Iron Flange Ball Valve

The Cast Iron Ball Valve with Flange, supplied by Zhongguan Valve, is a flanged ball valve suitable for medium- and low-pressure applications, providing long-term, stable supply to manufacturers, suppliers, and factories in China. This product features a high-quality cast iron valve body and a standard flange connection, suitable for fluid control systems handling common media such as water, oil, and gas. During the design phase, we prioritized corrosion resistance, sealing performance, and installation compatibility to meet the practical needs of water treatment, heating, and industrial piping systems.

Product Introduction

In conventional industrial piping systems, structural stability, ease of maintenance, and reliable sealing are crucial factors in selecting ball valves. The Cast Iron Flange Type Ball Valve uses a high-strength cast iron valve body, capable of withstanding long-term operation in medium- and low-pressure environments. The cast iron material offers excellent resistance to corrosion from water, oil, and low-pressure gases, maintaining structural stability under normal operating conditions.


The flange connection is designed according to international standards, ensuring compatibility with existing piping systems, simplifying installation, and helping to reduce future maintenance costs. Cast Iron Ball Valve with Flange is widely used for flow control in water treatment systems, heating pipelines, and municipal engineering projects.


Structural Design and Material Advantages


1. Valve Body Material – High-Quality Cast Iron

Good mechanical strength


Suitable for medium and low pressure environments


Resistant to corrosion from water, oil, and gas


Reasonable cost-performance ratio, suitable for large-scale projects


2. Precision Ball Structure

The internal ball of the valve undergoes surface treatment to improve wear resistance and corrosion resistance. It maintains stable sealing performance even under frequent opening and closing and high-load operating conditions.


The ball forms a stable sealing structure in both fully open and fully closed states, helping to reduce the risk of leakage and improve system safety.


3. Flange Connection

Complies with international standards (e.g., DIN / ANSI / GB optional)

Stable installation

Suitable for large-diameter piping systems

Easy for disassembly and maintenance

Performance Advantages
