I. Overview of J-Valves 20-inch 150LB Flanged Gate ValvesThe J-Valves 20-inch 150LB flanged gate valve is a valve specifically designed for high-pressure working conditions. Its main features are as follows:• Large Diameter Design: With a diameter of 20 inches, it can meet the pipeline requirements

CHECK VALVES and GATE VALVES are two common types of valves in industrial piping systems, which are respectively used to prevent the backflow of media and control fluid flow. However, due to the differences in their designs and working principles, there are significant differences in their performance in terms of reliability. This article will conduct a reliability assessment of these two types of valves from multiple perspectives to help users choose the appropriate valve types.

ISO 14726 Standard OverviewISO 14726 is an international standard that specifies the requirements for the design, manufacturing, and testing of valves, particularly for corrosive environments. It covers various types of valves, including ball valves and gate valves, and provides detailed guidelines

In the industrial field, J-VALVES red flange gate valves have become an ideal choice in numerous scenarios with their unique charm. Inside industrial plants, the pipelines in industries such as chemical and petroleum are crisscrossed, just like a complex network. The red flange gate valves stand out conspicuously in this "steel jungle". When workers conduct inspections and operations, they can quickly locate these valves due to their eye-catching red color and efficiently control the cut-off or conduction of fluids, ensuring that the production process proceeds in an orderly manner. The professionalism they convey also meets the strict requirements of high-quality valves in industrial production.

In the complex environment of industrial production, safety is always the top priority. The 300LB forged long-stem gate valves made in China by J-VALVES are a solid shield safeguarding industrial safety, leaving you free from worries.

Butterfly Valves in the Chemical IndustryDesign and Performance• Compact Structure: Butterfly valves are known for their compact design, which makes them suitable for applications with limited space. They consist of a circular disc that rotates around a central axis to control fluid flow.• Low Flow
