Screwed Bonnet Needle Valves-Socket Weld Type

The Screwed Bonnet Socket Weld Needle Valve is a high-integrity shut-off valve featuring a threaded bonnet-to-body construction and socket weld end connections.
It is designed for high-pressure and high-temperature service, providing precise flow control and a secure, permanent weld connection in instrumentation or process systems.

Typical Type Of Needle Valve:

a. Straight Type Needle Valve: Inlet and outlet ports are inline (180°).

b. Angle Type Needle Valve: Inlet and outlet at 90°.

c. T-Pattern (Globe Type): Flow turns 90° internally with top-mounted stem.

d. Cross Type Needle Valve: Four ports (two inlet/outlet pairs).

Anhui Hongji (Valvento) Needle Valves

The screwed bonnet needle valves socket weld type are types of valves used for precise flow control of liquids or gases in a system. It is designed with a long, tapered needle-like plunger that fits into a similarly shaped seat. The valve’s construction allows for very fine adjustments to the flow, making it ideal for applications where precise control is needed.

Applications:

• Flow Regulation : screwed bonnet needle valves union weld type used in systems where the flow needs to be controlled very precisely, such as in gas or liquid pipelines.

• Testing and Calibration : Frequently used in instrumentation, laboratories, and process control applications to calibrate equipment and regulate test fluids.

• Gas and Liquid Distribution : Hongji Needle valves are common in gas and liquid distribution systems, including those in pharmaceuticals, food and beverage, and oil and gas industries.

• Pressure Control : Often used for controlling the pressure and flow of sensitive or hazardous fluids in applications like fuel systems, high-pressure systems, or critical fluid handling systems.
