Product Description

Product Description

Needle Valves 

The needle valve made by Hongji Instrument& Valve Manufacturing Co., Ltd. is a type of valve with a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, They are also usually used in flow-metering applications, especially when a constant, calibrated, flow rate must be maintained for a certain duration, such as the idle fuel flow in a carburetor, steam in the pipe from the power plant, as well as to provide shut off for the pressure gauge or on applicators in many industries.

1. Needle Valve Features& Applications:

• Accurate& Precise control flow rate and pressure.
• Provide reliable cutoff.
• Precise adjustment of flow, bearing resistance, and pressure regulation.
• Also can be used in pump start, turbine by-pass, flow discharge, air regulation, and Reservoir inlet.
• Small Size.

2. Variety of Needle Valves( Manually Operated, Forged Stainless Steel):

• Inlet/Outlet: Straight type, Tee Type, Elbow Type, Y type

3. Needle Valve General Data:

• Pressure Range: 5000Psi-15000Psi(344Bar-10343Bar)
• Working temperatures: -54°C-649°C (-65°F-1200°F)
• Size:1/8''-1''(NPT), DN6-DN20, 
• Connection: Dual Ferrules, Flange, Thread, Welding.
• Application: Liquid or Gas, Steam, Water
• Body Material:304, 1316,316L, 321, Alloy
