    Sanitary Double Check Valve-An Overview

    What is a check valve? A check valve, or a one-way valve, is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. It is a type of two-port valves. In other words, it has two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. The check valve is available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valve work automatically and most are not controlled by a person or any external…

    Two Basic Types of Butterfly Valve: Lug & Wafer

    About butterfly valve Butterfly valves have been around for a long time and have been used more and more widely in various industries since the 1930s when they first came out. Butterfly valves are usually made of cast iron and their name is based on the function of their discs. There are several different types of butterfly valves, but there are always two basic types of butterfly valves — lug and wafer. Butterfly valves are classified as “quarter turn” valves. The valve can be opened or closed by rotating the metal disk of the butterfly valve a quarter turn. When the butterfly valve is fully open, the fluid is allowed…

    An introduction to Sample Valve

    A sampling valve is a valve used to take a sample of a medium in a pipeline or equipment. It can be used in many cases where chemical analysis of media samples is required. Here is how most sample valve works: According to the working principle or performance in the sampling process, the sampling valves are mainly divided into four types, including double opening valves, flange clip valves, sampling valves with thermal insulation jackets and aseptic sampling valve. Double open valve The double open valve is a more common sampling valve characterized by safe and stable sampling. It is usually composed of two connected ball valves. Sampling process: first close…

    Comparison between floating ball valve and Trunnion ball valve

    What is a ball valve? A ball valve is a one-way valve that is opened and closed by pressure on a ball which fits into a cup-shaped opening. Generally, a ball valve has two entries, but there is also 3-way ball valve, as shown below. A 3-way ball valve has three entries. It may have an L or a T design as shown in the picture below. Depending on your own requirement, you can arrange the entries of the 3-way ball valve in the following three-way. 1. One inlet and two distribute 2. One inlet and one outlet with diverting a flow 3. Straight pass the fluid without No inlet…

    Sanitary Valves for Industrial Perfume Manufacturing

    Perfume is one of our important cosmetics, both for women and men. It is a mixture of fragrant essential oils or aroma compounds, fixatives and solvents sprayed on the clothes, handkerchiefs or hairline to give a pleasant aroma. But do you have any idea about how the perfume is made? Generally, once the designers got the raw material they need for their perfume, they can start to make their perfume. The manufacturers distill the raw materials to get the essential oil and mix the essential oil with a designed percentage. Then, they need to add some alcohol products to ensure the high quality of the perfume. Perfume preparation in laboratory…

    Valve Collection: 8 Types of Valve

    Gate Valve The gate valve is one of the most commonly used on-off valves that utilizes the gate to turn on (fully open) and cut off (fully closed) the media in the pipeline. The gate is lifted and lowered in a plane perpendicular to the center line of the gate seat passage and cut the medium in the pipeline like a gate, so it is called a gate valve. This type of valve cannot be used for throttling. Feautures: 1. The flow resistance is small. The inner medium passage of the valve body is straight so the medium flows in a straight line and the flow resistance is thus small.…

    Types of Valve and Their Pros and Cons

    Gate valve A gate valve is a valve that moves the closing member (gate) in the vertical direction of the channel axis. It is mainly used fully open or fully closed to shut off the medium in the pipeline. In general, gate valves are not available for regulated flow. It can be applied to low-temperature and low pressure or high temperature and high pressure, related to what kind of materials it is made of. However, gate valves are generally not used in pipelines for transporting media such as mud. Advantage 1 The fluid resistance is small; 2 The required torque for opening and closing is small; 3 can be used…

    Different Subtypes of Butterfly Valves

    Over the years, butterfly valves have become increasingly popular due to the thin profile between their flanges. The butterfly valve weighs less than other valves and has a smaller footprint and lower initial cost. A butterfly valve is a flow regulating disc valve in which the obturator rotates about an axis that is at right angles to the direction of flow. In other words, the butterfly valve consists of a disc in which a rod is constructed by an intermediate or additional offset. When opened, the valve flaps 90 degrees in the valve bore, in line with the direction of fluid flow, and the fluid passes smoothly; the butterfly valve…

    Sanitary Valves: The Best Choice For Food Industry

    In the process of food manufacturing, antiseptic equipment, including valves used by quality control personnel to simply and safely transport liquids in pipelines and vessels, are vital to make sure the security of the food as well as its consumers. Therefore, sanitary valves are far more preferred in food industry than common industrial valves. What does “sanitary” means? Sanitary means “clean and not dangerous for your health or protecting health by removing dirt and waste”. Since we consume food into our body, the safety of the food is directly related to human health. Sanitary valve used in food processing can reduce the possibility of contamination from harmful pathogens, during transportation.…

    How to Maintain the Sanitary Diaphragm Valves?

    In the previous article An Overview of Diaphragm Valves, you have already known what the diaphragm valve is. Its opening and closing part is a piece of the diaphragm made of soft material, which is used to separate the body cavity, cover cavity and the drive parts. Sanitary diaphragm valves is a special type of diaphragm valve which has higher specifications and is safer and more hygienic. The main material of sanitary diaphragm valves is stainless steel. Although the stainless steel sanitary diaphragm valve has a better performance than the ordinary valve, one thing similar is that all kinds of valves have a service life and maintenance cycle. Regular maintenance…
