Stainless Steel Pipe Network Butterfly Valves

The Stainless Steel Pipe Network Butterfly Valves is a general-purpose control valve specifically designed for various fluid transmission pipeline systems. Its valve body and key pressure-bearing, sealing components are all made of stainless steel materials (304, 316, 304L, 316L, 2205 duplex stainless steel, etc.). The valve drives the stem to rotate via an actuator, enabling the disc to open, close, or regulate inside the valve body, thereby achieving shut-off and flow control of media in the pipeline network.

Featuring a compact structure and high bore utilization rate, this valve offers unobstructed flow passages and low pressure loss in the open state, making it ideal for installation in pipeline systems with space constraints or dense pipelines. The stainless steel material provides excellent corrosion resistance, oxidation resistance, and media erosion resistance, ensuring long-term stable operation in complex media and harsh environments.

The Stainless Steel Pipe Network Butterfly Valves is widely used in pipeline systems such as municipal water supply and drainage, industrial circulating water, petrochemicals, food and pharmaceuticals, and environmental treatment. It is particularly suitable for engineering scenarios with high requirements for media cleanliness, corrosion resistance, and operational reliability.

Structure & Working Characteristics

1. Valve Body Structure Configuration

Based on the pressure class and operating conditions of the pipeline network, Stainless Steel Pipe Network Butterfly Valves can be configured with various structural types:

● Center-line Type Structure: The rotation center of the disc coincides with the center line of the valve body. It features a simple structure and low flow resistance, suitable for low-pressure, large-flow pipeline networks.

● Offset Type Structure: Including single-offset, double-offset, and triple-offset designs. The sealing pair disengages quickly during opening and closing, suitable for medium-high pressure, high-frequency opening/closing, or high-temperature working conditions.

The valve body is usually manufactured via precision casting or welding forming processes to ensure overall strength and dimensional stability. The disc and stem adopt a rigid connection to guarantee reliable transmission.

2. Sealing Structure Design

To adapt to the requirements of different pipeline media and working conditions, the valve can be equipped with the following sealing types:

● Soft-seal Structure: Composed of EPDM or fluororubber compounded with a stainless steel skeleton, suitable for low-pressure, clean, or hygienic-grade media.

● Metal Hard-seal Structure: Stainless steel metal sealing surfaces or Stellite alloy overlay welding, suitable for high-temperature, high-pressure, particle-containing, or corrosive media.

Reasonable sealing configuration ensures sealing performance while reducing wear during opening and closing and extending the service life of the valve.

3. Drive & Control Methods

The valve can be flexibly equipped with actuators according to the control mode of the pipeline network:

● Manual Drive: Suitable for small-diameter, low-pressure, or manually controlled pipeline networks.

● Pneumatic Drive: Suitable for high-frequency opening/closing and on-site automated control systems.

● Electric Drive: Suitable for remote control, centralized management, or pipeline networks requiring precise flow regulation.
