Lug-Type Soft-Seal Butterfly Valves Are Used In Piping Systems

Butterfly Valve Introduction

This is a wafer-type soft-seal butterfly valve, belonging to industrial valve equipment.

These butterfly valves use blue cast iron or cast steel valve bodies, equipped with internal rubber soft-seal valve seats and metal discs, providing excellent sealing performance. They are suitable for pipeline systems carrying water, air, and mildly corrosive media, used to control the flow of fluids. Their wafer-type connection is secured by flanges on both sides of the pipeline, making installation convenient and space-saving.

Butterfly Valve Main Materials

Advantages of Butterfly Valves:

1. Excellent Sealing Performance: Utilizing soft sealing materials such as rubber and PTFE, the valves fit tightly against the butterfly plate, achieving a zero-leakage seal. This is particularly suitable for applications requiring strict media shut-off (e.g., isolation of drinking water and chemical raw material pipelines).

2. Compact Structure and Easy Installation: The wafer-type connection eliminates the need for large flanges; it is fixed simply by clamping the flanges on both sides of the pipe, saving installation space. This is especially suitable for applications with small pipeline spacing and compact layouts (e.g., municipal pipe networks and small equipment pipelines).

3. Low Flow Resistance and Energy Efficiency: The butterfly plate has minimal obstruction to the fluid when open, resulting in a low flow resistance coefficient. This reduces energy loss in the pipeline system, making it suitable for transporting large flow rates of media (e.g., urban water supply and air conditioning water circulation systems).

4. Low Cost and Easy Maintenance: The valve body is mostly made of cast iron or ductile iron, and the seals are easy to replace. Overall procurement and maintenance costs are lower than hard-seal or other types of valves, offering excellent value for money.

5. Wide Applicability to Various Media
Suitable for cleaning media such as water, air, oil, and mildly corrosive liquids, with wide applications in municipal, construction, and general industrial fields.

6. Low Operating Torque and Flexible Adjustment
Easy to operate manually, and can be automated remotely controlled with electric/pneumatic actuators, facilitating precise flow adjustment (such as flow distribution in HVAC systems).
