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.

How to Select Valves in the Chemical Industry? Hard-Seal vs. Soft-Seal Gate Valves
Hard-seal valves are suited for extreme conditions (high temp/pressure, corrosive/abrasive media), offering long-term reliability. Soft-seal valves provide cost-effective sealing in mild environments. Select based on operational demands, media properties, and budget to optimize safety, reliability, and cost-efficiency.

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...

Understanding the Distinction: Wafer Butterfly Valve vs. Flange Butterfly Valve
In the realm of fluid control systems, butterfly valves play a crucial role in regulating flow. Among the varieties of butterfly valves available, the wafer butterfly valve stands out for its compact design and versatile application. The term "butterfly valve" refers to a valve that uses a circular disc or vane to regulate flow by pivoting on an axis perpendicular to the direction of flow.
