A sludge pinch valve helps wastewater plants control thick, sticky, and solids-heavy sludge. It closes by squeezing a rubber sleeve, so sludge does not pass through seats, stems, or small inner parts. This makes the valve useful for sludge lines that often clog, wear, or need regular cleaning. This guide explains why pinch valves work […]
? Lianke Valves Secures Major Export Order for 1,685 Units of Pinch and Lined Valves Our international business continues to thrive as we have recently signed a significant export order involving 1,685 units of pinch valves and fluorine-lined valves.This successful deal is not only a testament to the long-term trust between both parties, but also […]
What is A Diaphragm Valve? A diaphragm valve is a type of valve that uses a flexible diaphragm to control the flow of fluids. This valve is part of the linear motion family, which means the moving parts go in a straight line—not in circles like ball or butterfly valves. The elastomeric diaphragm in diaphragm […]
Ball valves are quarter-turn valves widely used to control the flow of liquids and gases in pipelines. They use a rotating ball with a bore through the center to open or block flow, providing quick shut-off and reliable sealing. Among the different designs, full-portand standard port ball valves are two common options. The main difference […]
Your valve is leaking because something has gone wrong with its sealing system. Maybe the seals are worn out after years of service. Perhaps debris is stuck between critical surfaces. Or it could be that improper installation created misalignment from the beginning. These common problems prevent the valve from achieving perfect closure when you need […]
Valve Flow Coefficient (Cv) is a measure of a valve’s capacity to allow liquid or gas to flow through it. It’s technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop of 1 psi across the valve.” You calculate Cv by […]
When selecting the right valve for industrial applications, understanding pressure and temperature ratings is crucial. Many professionals in the field struggle with terms like Class, Rating, and PN, which can lead to costly mistakes if misunderstood. This guide will help you understand these concepts so you can select valves with confidence. What Do Pressure Units […]
The main difference between plastic and elastomer comes down to flexibility and shape retention. Plastics are rigid or semi-rigid. Once they bend or break, they don’t bounce back. Elastomers are flexible. They stretch, twist, or compress and return to their original shape. Below, we’ll take a closer look at how these materials differ and the conditions […]
Polyurethane and rubber differ in durability, flexibility, and resistance to wear. For manufacturers, it often comes down to the application. Some industries need the toughness of polyurethane, while others rely on the flexibility and impact absorption of rubber. Let’s take a closer look at how these materials compare and where each one performs best. What […]
Viton and EPDM differ in their temperature range, chemical resistance, and flexibility. In industrial applications, manufacturers often use Viton to handle fuel, oil, and high-temperature environments. In water-based systems, EPDM makes for a better seal due to its resistance to steam and weather conditions. Let’s take a closer look at how they compare. EPDM vs […]
