Stainless Steel Welded Globe Needle Valves
The name "Stainless Steel Welded Globe Needle Valves" refers to the mechanism of the valve's small, tapered plug and port. The needle valve's tiny size allows for fine fluid flow control. When pressure or flow needs to be safely lowered or controlled, needle valves are utilized.
Stainless Steel Welded Globe Needle Valves
Stainless Steel Welded Globe Needle Valves are named for their narrow tapered plug and port mechanism. The small size of the needle valve provides precise control of fluid flow. Needle valves are used when pressure or flow must be safely reduced and controlled.
The constitute of Stainless Steel Welded Globe Needle Valves
Needle valves consist of a body with an orifice and a tapered stem that can be screwed in and out to change the orifice opening, and with the help of the needle valve, flow in both directions can be restricted. The preferred direction of flow is indicated by an arrow in the valve body, and when the flow is in that direction, there will be less pressure loss through the valve. Needle valves with internal check valves allow restricted flow in one direction and free flow in the other. Needle valves use the stem to change the size of the orifice, this will allow us to compensate for changes in differential pressure to maintain a constant flow rate through the valve and a constant actuator speed, it also allows the establishment of desired flow rate.
The advantages of Stainless Steel Welded Globe Needle Valves

Smaller needle size
They can be used for throttling purposes
Flow can be precisely adjusted
Needle valve used as vent valve for hot water heating
These valves can be easily closed
The application of Stainless Steel Welded Globe Needle Valves
they can be used for exhaust pipes
These valves can be used in sampling lines and other abrasive services
fluid power system
These valves are used in flow metering applications
Needle valves are used in automatic combustion control systems requiring precise flow regulation
Needle valves are used in constant pressure pump governors to reduce the effects of pump discharge pressure fluctuations
