  Valves are mechanical devices that control the flow and pressure of fluid in a hydraulic or pneumatic system. They are essential components of the  Duplex Pipe  system transporting liquids, gases, vapours, dirt, etc. Various types of valves are available, each with its characteristics, performance and function. There are also different types of actuators (manual, pneumatic, electric ...). How to choose a valve? To select the correct valve, it is necessary to define its function. Will it regulate or stop the fluid flow? Then it is necessary to check what type of substance will circulate: gas or liquid. Will it be a corrosive, chemically neutral, food-grade or medical liquid that requires special sanitary and hygienic conditions? It is essential to know the actuation system of the valve to determine whether it is manual or automatic. In the first case, the presence of a person on site is required to control the  904L Tube  valve. In the second case, the valve ca...

  The function of a valve is to control the flow of water and to stop it. It is present in industrial environments, even in our homes. This valve brings together many technical characteristics necessary for the various uses to which it is put. The function of the valve is roughly divided into three: "stop the flow", "fix the flow direction" and "adjust the flow rate and pressure". We will introduce the types and characteristics of valves as a guide for selection to exert these functions.   Butterfly valve Butterfly valves are used for water, hot water, oil, air, steam, slurry, etc. The lever is rotated to rotate the valve stem, and the valve body connected to the valve stem turns to control the fluid. A highly versatile valve that can be used for both ON-OFF and fluid adjustment. When to use a butterfly valve? The butterfly valve is mainly used to control the flow of a fluid. On the other hand, the butterfly valve cannot be used for liquids loaded...

  The selection of material is never due to a chance in the industry. During the design phase, the characteristics of the materials must be carefully studied and fixed to avoid any complications. This is even truer when it comes to choosing a material for a tube. Certain tubes are subjected to strong mechanical, thermal or even chemical stresses. The material from which the tube was made will have an influence on all manufacturing operations, including machining operations. The machinability of a tube depends directly on the material in which it was made. For each material, special precautions must be taken to guarantee quality machining. Machining is a common operation when preparing for welding.     Duplex steel A Duplex stainless steel consists of a chrome stainless steel and addition of nickel. This alloy has been designed to provide corrosion resistance and tensile strength. Duplex steel pipes are widely used in oil and gas exploitation on offshore sites where pipeli...

Needle valve - is a structure of fittings, a shutter moving along the sealing surfaces of the seat. It is made in the form of a narrow conical cylinder. The shape in which the shutter is made ensures a high level of tightness of the device and a smoother change in the cross-section of the passage. It is done with an increase and decrease in the volume of the working medium supply. The high degree of tightness of the valves allows them to be used for media in various states of aggregation - liquid and gaseous. Needle valves have no analogues and are produced by  Needle Valve manufacturer in India  only as single-seated ones. They are widely used in industry to completely shut off the flow of working material, as well as to regulate its pressure and flow. Device principle of operation The needle valve device includes a body, a cover, a plug, a stem (spindle). The valve is operated manually or using a drive. It does this by transferring the torque from the handle or actuator to t...
