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.…

Top 10 Valve Sealing Materials
Synthetic rubber Synthetic rubber is superior to natural rubber in its oil resistance, temperature resistance and corrosion resistance. Generally, the using temperature of synthetic rubber is lower than 150 °C (t ≤ 150 °C), and that of natural rubber is lower than 60 ° C (t ≤ 60 °C). Rubber is used for shut-off valve, gate valve, diaphragm valve, butterfly valve, check valve, pinch valve and other valves whose nominal pressure is smaller than 1 MPa (PN ≤ 1MPa). Nylon Nylon has the characteristics of small friction coefficient and good corrosion resistance. Nylon is mostly used for ball valves and globe valves with a temperature less than 90 ° C…

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…
