What is the Difference Between Cryogenic Ball Valves and High-Temperature Ball Valves?
As a common family of control valve, sanitary ball valves play a crucial role in the food and pharmaceutical industries. However, different working environments require different types of ball valves, among which cryogenic ball valves and high-temperature ball valves are two common variants. Let’s explore the differences between them. Sanitary ball valves are known for […]
Read moreGate Valve vs. Globe Valve vs. Check Valve – Principles, Applications, and Differences
Gate valves, globe valves, and check valves are three of the most fundamental and common types of valves. While their external appearances can sometimes be similar, their internal structures, working principles, and core missions are distinctly different. What is a Gate Valve? A gate valve is intended for the ON/OFF operation of fluid flow, involving […]
Read moreApplication of Pneumatic Control Valves in the Pharmaceutical Industry
The pharmaceutical industry is a crucial sector directly impacting human health, and it imposes extremely high requirements for precision, stability, and safety in production processes. Fluid control plays an indispensable role in pharmaceutical manufacturing, from raw material handling to drug synthesis, purification, and final packaging. As an important fluid control device, pneumatic control valves (pneumatic […]
Read moreGuide to Common Valves
Valves are essential components in fluid control systems. And they are used to regulate the flow rate, direction, and pressure of fluids. Common Types of Valves Gate Valve: Primarily used to block or allow the flow of media in pipelines. It is a simple structure and low cost. Globe Valve: A frequently used valve suitable […]
Read moreSealing Technology for Sanitary Valves: Dynamic Sealing and Static Sealing
The sealing performance of sanitary valves is crucial, as issues like leakage, spurting, dripping, and seeping often originate here. Based on whether there is relative motion between the sealing surfaces, seals can be categorized into dynamic seals and static seals. What is a Dynamic Seal? A dynamic seal refers to a seal achieved between components […]
Read moreWhat are the End Connection Types for Valves?
The main types of valve connections include flanged connection, welded connection, threaded connection, sleeve connection, clamp connection, and wafer connection. 1. Flanged Connection For pipelines larger than 2 inches, flanged connections are the most commonly used method. Valves with flanged connections are easy to install and disassemble. They are also widely applicable in terms of […]
Read moreAre All Valves Closed Clockwise and Opened Counterclockwise?
In daily life, we use many valves. We might follow a simple rule: “Turn right to tighten (clockwise), turn left to loosen (counterclockwise).” But is this rule always true? Are all valves really closed clockwise and opened counterclockwise? The answer is: Yes, in most cases. But there is a very important exception. The General Rule: Righty-Tighty, […]
Read moreWhere Should a Check Valve Be Installed?
How is the installation location of a check valve determined? What is the difference between installing a check valve before the pump versus after the pump? Where is pre-pump installation suitable? Check valves are often used with other valves. So, where should the check valve be installed when used in combination with other valves? Let’s […]
Read moreAre Breather Valves and Pressure Relief Valves the Same Type of Valve?
Breather Valves and Pressure Relief Valves (PRVs) are two very common and important types. Both are related to pressure management, so many people wonder if they are the same device. The answer is: No. Although they may sometimes be used in the same device, they are fundamentally different in their design purpose, working principles, and […]
Read moreGuide to Choose Sanitary Butterfly Valves
Sanitary butterfly valves are key parts in fluid control systems. They are widely used in industries with strict hygiene needs, like food, beverage, pharma, biotech, and cosmetics. These valves help control fluid flow accurately while keeping the product safe from contamination. Picking the right type and size is very important. It affects how well the […]
