PTFE/PFA Lined Plug Valve: Anti-Corrosion Solution for Highly Corrosive Working Conditions
19 Jun, 2026
Industries such as chemical, pharmaceutical and wastewater treatment often handle highly corrosive media including strong acids, alkalis and organic solvents. Conventional metal plug valves are in direct contact with process media, so they easily suffer from corrosion, wear, leakage and clogging during long-term service. Frequent maintenance and production downtime greatly raise operational costs, making them unable to support stable long-term operation in corrosive services.
High-Performance 904L Plug Valves for Corrosive Service in Chemical Projects
02 Jun, 2026
On June 1, 2026, over at Zhengzhou Jinggong Technology (ZZJG VALVE)'s production workshop, a batch of 904L super austenitic stainless steel plug valves wrapped up their final quality checks, got packed up tight, and hopped onto the delivery trucks. They're all set to head to a big-time chemical project in Southeast Asia! These valves will handle precise on/off control for super corrosive media—total lifesavers for keeping the customer's core production line running smooth and steady.
Third-Party Inspection Process for Plug Valves
29 May, 2026
In order to help you understand the complete process of the third-party inspection of the plug valve, the following is a specific description of the steps we coordinate and conduct on-site witnessing inspections with BV, DNV or SGS. We have four stages of the whole process.
Structural Differences and Application Selection of Lubricated and Non-Lubricated Plug Valves
19 May, 2026
Widely used in oil and gas, chemical and municipal water supply fields, plug valves are mainly divided into lubricated and non-lubricated types, with obvious differences in structure, performance, typical categories and applications.
Plug Valve Selection for New Pipelines: 4 Core Questions to Answer Before Procurement
12 May, 2026
In the new pipeline projects, the plug valve as crucial cutting-off or regulating equipment, its selection directly affects the long-term reliability, safety and economy of the system. However, many purchasing personnel, when confronted complex technical specification, tend to fall into trap of "overloading with parameters", thereby neglect the core decision-making logic. 70% of pipeline valve failures are caused by incorrect selection rather than product quality issues.Senior engineers emphasize that the following 4 questions must be accurately answered before procurement to avoid hidden dangers from the source.
