Specialityvalve is the leading Needle Valve Manufacturer in India. Needle Valve is a type of valve with small port and threaded, needle shaped plunger which is why sometimes referred to as Plunger Valves.
It is used to accurately control flow rates of clean gases and fluids. It got its name due to the narrow needle-like plug and port arrangement. It is used where continuous throttling is required.
The amount of air or oil passing through the valve can be decreased or increased by using the Needle valve, which controls an opening within the valve by a needle. The speed of the piston of an air cylinder can also be regulated by using this valve.
Specialityvalve is the leading Needle valve manufacturer in India. Needle valve typically spoken as plunger valves, area unit regulation valves and change engineers to finely manage and regulate water flow and pressure. The preciseness is achieved through the fine movement of the shaft, which permits the casing to maneuver the piston tube in slippery motion towards gap or closing position, betting on the necessities from the system.
Needle valve could be a manual valve that used wherever continuous asphyxiation of flow is needed for regulation. Needle valves area unit the same as the world valve in style with the largest distinction is that the sharp needle-like disk.
Needle valves area unit designed to provide terribly correct management of flow in tiny diameter piping systems. They get their name from their end round shape disc and matching seat.
Needle Valve work flow:
Fluid flowing through the valve turns ninety degrees and passes through a passageway.Thanks to the needle form disk, an exact portion of the disk can meet up with the seat gap before the disk comes in touch with the seat, which has to match the tapered style as a disk. This arrangement permits an awfully gradual increase or decrease within the size of the gap.
Advantages of Needle Valves:
· Controlling fluid media is easy.
· Ideal for vacuum services or any system requiring consistency.
· Sealing the valve needs less amount of mechanical force.
Applications of Needle Valves:
· Low-pressure hydraulic systems, chemical processing, and other gas and liquid services are common applications.
· Used to precisely control and adjust the fluid flow.
· When a lower flow rate is needed, this valve is used.
· Needle valves can also be used as both on/off and throttling valves.
It has use in almost every industry and main role of needle valve is to control flow, to start the pump, for pressure regulation, flow discharge, air regulation and reservoir inlet.

• PN10-PN450
• Size – 1/2” –72”
Uses
• It is used where the flow needs to stop immediately
• Used as an on/off and throttle valve
• Used on gas blender lines
• To control the flow, all analog field instrument are installed with it
• Helpful for sample points in piping where little flow rate is required
Advantages
• Valve flow control available at very low rate with higher accuracy
• Flow rates can be adjusted precisely
• Operation is easier
• There is no space problem as it requires less space
Disadvantages
• Used only for low flow rate piping system
• Not able to examine the opening and closing by looking at the handle
• If the solid has solid particles, then it can damage the seat and the needle
• High pressure loss
