PP pinch valve, as the name suggests, is a pinch valve of PP shell material. The main advantage of this valve is that the valve body is made of pp plastic, so the valve body is lighter and can be installed on the suspended pipe. PP material has the characteristics of acid and alkali resistance […]
This guide explains what a basket-type strainer is, how it works, and how to choose the right one for your line. A strainer basket type helps catch dirt, rust, scale, and other solids before they reach pumps, valves, or machines. This keeps the flow cleaner and helps reduce damage in busy pipe systems. Lianke Valve […]
Choosing the right valve can look simple at first. Then the small details start to matter. Size, pressure, heat, flow, and fluid type can all change what works best. This guide explains what the valve does, how the 90-degree turn works, and how 1-piece, 2-piece, and 3-piece designs differ. It also gives simple size data […]
Choosing the wrong lining for a chemical valve in acid service is an expensive mistake. The wrong coating cracks, contaminates your process fluid, or fails under pressure — sometimes all three. Two coatings dominate this space: glass lining and fluorine lining (PFA). Both work. But they suit different conditions, and specifying the wrong one costs […]
Choosing the right valve for a petrochemical plant is a safety decision, not just a purchasing one. When your pipeline carries flammable liquids or gases — such as benzene, ethanol, or liquefied petroleum gas — even a tiny spark can cause a fire or explosion. This is why selecting the right petrochemical valves is critical […]
Picture this: your process line must send fluid to two different tanks, and two reagents need blending before the reactor. The old setup uses multiple two-way valves, tees, and separate actuators. It works, but it’s costly, takes up space, and adds maintenance headaches. A 3-way lined ball valve handles both tasks in a single body. […]
Backflow is one of those problems that looks minor on paper but can shut down an entire process line in practice. A check valve is the simplest fix. It lets fluid move in one direction and stops it from reversing. But walk into any valve supplier’s catalog, and you’ll quickly face a choice: swing check […]
Choosing the wrong metal for a seawater pipeline is an expensive mistake. It leads to early valve failure, unplanned shutdowns, and high repair costs. Two of the most common materials used in marine and desalination systems are 316 stainless steel and Duplex 2205. Both are good metals — but they perform very differently in saltwater […]
P&ID (Piping and Instrumentation Diagram) valve symbols, also referred to as p and id valve symbols or P&ID valve symbols, are essential tools for engineers, EPC teams, and maintenance crews. They allow quick identification of valve type, actuation method, and fail-safe position directly on process diagrams. This guide serves as a quick-reference library of the […]
Lined valve low fugitive emission solutions help address a major challenge in modern industrial facilities. Fugitive emissions represent a major challenge for modern industrial facilities. These unintentional leaks of gases or vapors happen at process equipment connections, gaskets, and seals, negatively affecting environmental safety and operational emissions efficiency. Regulating these leaks is a primary objective […]
