When to use needle valve?
This Valves used with higher differential pressure, and our valve standard range covers a pressure range up to PN40, and on request up to PN100. It can be manually actuated or can be controlled by electrical, hydraulic or pneumatic actuation.

Check Screwed Bonnet, Cryogenic and Flanged Needle Valves Pressure Ratings
Needle Ball Valve Pressure Rating
pressure of up to 4,000 to 5,000 psi (275 up to 413 bar) at 100°F (38°C)
Difference Between Needle Valve And Ball Valve
| Needle Valve | Ball Valve |
| It can adjust the flow rate | ball valve can not adjust the flow |
| It needs to be screwed a few times when this valve is fully opened, | It only needs to turn 90° |
| It is also called as plunger valves | It is Categorized in low pressure and high pressure Ball Valve. High pressure ball valve used in Hydraulic system. so ther are called as hydraulic ball valve |
| Use to Control and regulate water flow and pressure | used to control flow, pressure control in gas distribution systems and pressure reduction in connection with gas storage. |
| More Expensive | Less Expensive |
