In industrial pipeline fluid control systems, flange gate valves, as one of the most commonly used cut-off valves, have become the preferred products in multiple industries such as petroleum, chemical, power, metallurgy, municipal, etc. due to their excellent sealing performance, low flow resistance structure, and wide applicability. As a professional industrial valve manufacturer, Paili Valve Group Co., Ltd. has accumulated rich experience in the design, production, and application of flange gate valves. Its products are widely praised in the market for their excellent quality and technical reliability.

1、 Product Structure and Working Principle

A flange gate valve is a type of straight through valve that uses a gate as the opening and closing component and drives the valve stem up and down through a handwheel or actuator to control fluid flow. Its two ends are connected by standard flanges, which has good sealing and versatility, and is easy to install and disassemble. It is widely applicable to pipeline systems of various diameters and Pressure grades.

The flange gate valve produced by Paili Valve has a rigorous structural design, with common types including wedge-shaped rigid gate and elastic gate to adapt to different media and working conditions.

2、 Product performance advantages

The flange gate valve products of Paili Valve Group always adhere to technology as the core and quality as the foundation, and have the following outstanding advantages:

1. Full bore design, with minimal flow resistance

When the valve is fully opened, the medium channel is kept consistent with the inner diameter of the pipeline, and the flow resistance is almost zero, which is particularly suitable for systems that are sensitive to pressure drop requirements.

2. Good sealing and reliable cutting

The metal sealing pair design adopts precision machining, and the gate and valve seat are in close contact to ensure bidirectional sealing, eliminate the risk of medium leakage, and meet the cutting requirements of high-pressure or corrosive media.

3. Flange connection, stable structure

Flange connection is applicable to various Pressure levels, with good anti vibration performance and stable operation in high-strength industrial scenarios.

4. Various Material, wide adaptability to working conditions

Poly can provide a variety of Material, including cast iron, ductile iron, carbon steel, stainless steel, alloy steel, etc., which are suitable for water, steam, oil, gas and corrosive media.

5. Smooth opening and closing, with multiple driving modes available

According to customer needs, we provide various opening and closing forms such as manual, electric, pneumatic, and hydraulic to meet different requirements from traditional control to automation systems.

3、 Widely applicable in various fields

The wide applicability of flange gate valves makes them an irreplaceable control component in multiple industries. The Paili flange gate valve product has been successfully applied to:

Petrochemical industry: used as the main control valve in crude oil, refined oil, and chemical liquid pipeline systems;

Power industry: safety control devices in high-temperature and high-pressure water and steam systems;
