The movement path of the metal sealing valve has the characteristics of both gate valve (multi-turn) and sanitary ball valve (90-degree turn), so its performance has the advantages of both gate valve and ball valve. The structures of the metal sealing valves and sanitary ball valves have similarities and differences, as is discussed below. Similarities: 1. Both of the metal sealing valve and sanitary ball valve can achieve metal sealing and endure high temperature. 2. They share the same way of operation. They can be operated by hand wheel or bevel gear box. 3. They share the same way of valve stem action. Lift first to make the valve flap…

4 Metrics for the Quality of Sanitary Pneumatic Ball Valves
The switch control of the Sanitary Pneumatic Ball Valves is a top priority. This affects a series of production of sanitary valve production and transportation. The valve should be sealed and pressure tested. If the valve switch can be used normally, and there is no leakage during the pressure test, the valve is qualified. The valve is the control component of the fluid line. The body, disc and sealing surface of the valve need to meet the corresponding requirements in order to avoid corrosion. Generally speaking, the requirements for valve strength are mainly considered from the various conditions of temperature, corrosivity and pressure of the medium. When the valve is…

Press Drop: An Important Selection Criteria for Choosing Control Valves
Pressure drop, also known as pressure loss, is an important selection criteria for control valves as it’s used in the sizing calculation. Let’s define the term pressure drop, show how it’s calculated, and discuss why it’s important for engineers designing flow systems. Definition of Pressure Loss Pressure drop is the difference in pressure as measured between two points in a pipe with flowing fluid. For a control valve, the pressure drop is the difference between the inlet pressure and the outlet pressure. It varies with the flow. Calculation of Pressure Loss The calculation for pressure drop looks like this △P=P1 + P2. The pressure drop is usually measured in pounds per…

Development History of Butterfly Valve
Butterfly valve developing history In the 1930s, the United States invented butterfly valves. This valve has a small operating torque, a small installation space and a light weight. Taking DN1000 as an example, the butterfly valve is about 2T, but the gate valve is as heavy as 3.5T. The butterfly valve is easy to combine with various driving devices, and has good durability and reliability. The relationship between the opening of the butterfly valve and the flow rate changes substantially linearly. If used to control flow, its flow characteristics are also closely related to the flow resistance of the piping. For example, if the diameters, forms, etc. of the two…
