The Needle valve got its name because of its narrow needle like plug and port arrangement. The needle valves are small in size but fluid flow controlling is of exceptional accuracy. Needle valves are linear motion valves Which are used in instrument systems for throttling of
Gate valves are used when minimal pressure drop through the valve Is required. They are designed to permit a straight full and free flow or no flow at all. Gate valves are normally wide open or completely closed. PLUG VALVES Like gate valves plug valves are used primarily for non throttling on off service.

The globe valve body is divided into two halves by a partition or a baffle. These two halves can be connected by an opening at the center of the partitioning which divides the valve body in two halves. A small horizontal disc or plug is the closure member which can move up and down attached to the stem thus opening or closing the valve. This

Oct 10 2018 The needle valve is a valve that can be precisely adjusted. It is widely used such as the cutting distance for flame cutting. The knob for adjusting the flame temperature is a needle valve. The instrument needle valve is an important part of the instrument measurement pipeline system. It mainly has a globe valve type and a ball valve type.
Feb 08 2022 Flow control valves are necessary components in a broad range of industries. Determining which flow control valve type is best for your particular situation depends on a host of criteria but the most commonly used types include gate valves globe valves pinch valves diaphragm valves and needle valves.

Of 316 stainless steel as standard and some as alloy 400 Hy Lok needle valves are meticulously designed for the flow temperature and system required. Common applications include pharmaceutical life support and oil gas. End connection options include male / female NPT Hy Lok tube fittings and ISO threads from 1/8″ to 1″.
Globe valve is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction resulting
The needle valve has a mesh and machined body. This body can be forged carbon steel or stainless steel depending on the requirements of the services. A seat can be soft metal or composite similar to a globe valve. Needle valves are typically used in smaller sizes and are provided with screwed or socket weld endings.
Apr 02 2013 A needle valve is a type of valve having a small orifice and a threaded needle like plunger. It allows precise regulation of flow although it is
Jun 05 2020 Needle valves have sharp needle like a disk and are similar to a globe valve in design and these types of valves are designed to give very accurate control of flow in small diameter piping systems. In vacuum systems
Introduction to Plug valves Plug valves. A Plug Valve is a quarter turn rotational motion Valve that use a tapered or cylindrical plug to stop or start flow. In the open position the plug passage is in one line with the inlet and outlet ports of the Valve body. If the plug 90 is rotated from the open position the solid part of the plug
Globe valve working principle. This regulation of flow is achieved by the perpendicular movement of the disk to the seat. Globe valves are capable of controlling the flow automatically or manually. The gate valve is situated at a right angle which restricts the leakage. When the
Apr 01 2020 The needle valve got its name because of its narrow tapered plug and port arrangement. The needle valve is small in size and the control of the fluid flow can be done accurately. Needle valves can be used if the pressure heads or flow rates must be safely reduced and controlled. The needle valves are capable to control the pressure and flow.
