Selling the best price Needle Valve from suppliers & distributors

The types of valves that are usually found are as follows: 1. Gate valve This type of valve is usually used to withstand strong water currents. You will usually find this type of valve on oil well testing tools such as flowheads, chrismast trees, and choke manifolds. In this type of valve you cannot restrain the fluid flow by only half opening or closing it. The use of this valve must be fully open or fully closed. If you use this valve with only half open, the fluid flow can erode the gate corners, causing erosion and the valve can no longer be used. when opening / closing the gate you need to pay attention to calculate the rotation, this is so that the gate is not half open or half closed. 2. Ball / Plug valve Ball or Plug valve is used to open or close the fluid flow quickly. To operate this type of valve is easy because you only need to turn the handle so that the ball or plug changes direction by 90 degrees. This type of valve is not recommended to be used to restrain fluid flow, because fluid flow can cause erosion at the angle of the ball or plug and can cause the seal to break quickly. 3. Needle valve Needle valves are mostly used for systems or releasing fluid flow rates, where these valves can withstand pressures of up to 10,000 psi. How to use this type of valve can be said to be relatively easy, because you only need to turn the valve once or twice a meal, the fluid will start to flow. To stop the flow of fluid, you only need to turn the valve in the opposite direction from the direction you opened the valve. When the valve is completely closed, the fluid flow will stop. 4. Globe valve This type of valve can not only close the fluid flow quickly, we can also find this valve at the outlet / discarge pump. The system of this valve is when the handwheel is rotated clockwise, the disc pushes the globe position so that it closes the fluid flow and vice versa.
