WEIZIDOM Eccentric Metal-Seated Butterfly Valve Selection & Installation Guide
The eccentric metal-seated butterfly valve is a high-performance valve that utilizes an eccentric structural design combined with a metal-to-metal sealing pair. It is suitable for medium to high-pressure, high-temperature, and high-sealing-requirement working conditions. The sealing form typically involves metal-to-metal contact (e.g., stainless steel + hard alloy), or metal to flexible alloy coating, offering excellent wear and temperature resistance.

How to Select the Right Butterfly Valve?
A butterfly valve is a type of valve commonly used in fluid pipelines to isolate, regulate, or throttle the flow of media. Due to its simple structure, compact size, lightweight design, and fast actuation, it is widely applied in industries such as waterworks, chemical processing, petroleum, power generation, food and beverage, and pharmaceuticals.

Is Soft-Sealed Gate Valve Prone to Leakage?
The sealing performance of soft-sealed gate valves relies on elastic materials (e.g., rubber, PTFE). Over time, these materials may degrade due to temperature, media, or prolonged use, leading to hardening, cracking, or detachment, which compromises sealing and causes leakage.

What are the installation and contraindications for valves such as gate valves and butterfly valves?
During the installation process of gate valves, butterfly valves and other valves, the quality of the installation will directly affect the normal operation in the future, so you must pay attention to it. So, how to install gate valves and butterfly valves? Five key points for installing the five major valves: 1. Direction and location Many valves are directional: For example, stop valves, throttle valves, pressure reducing valves, check valves, etc., if installed upside down, will affect the use effect and life (such as throttle valves), or will not work at all (such as pressure reducing valves), or even Causing hazards (e.g. check valves). Generally, valves have direction marks on the valve body. If not, it should be correctly identified based on the working principle of the valve. The valve cavity of the stop valve is asymmetrical from left to right, and the fluid must pass through the valve port from bottom to top. In this way, the fluid resistance is small (determined by the shape), and it is labor-saving to open (because the medium pressure is upward). After closing, the medium does not press the packing, which is convenient for maintenance. , this is why the stop valve cannot...
