industial that we serve

Industries That We Serve

  • Needle valves are widely employed to regulate flow and protect sensitive gauges from damage caused by liquid and gas pressure surges. They’re suitable for systems with lower flow rates and lighter, less viscous materials.
  • Needle valves are commonly found in low-pressure hydraulic systems, chemical processing, and other gas and liquid applications. Because of the materials used, these valves may be used in high-temperature and oxygen applications.
  • Stainless steel, bronze, brass, or metal alloys are commonly used for needle valves. Therefore, it’s critical to select a needle valve made of the appropriate material for the job at hand. This will extend the life of the valve and keep your systems functioning smoothly and safely.

what is needle valve

What is a needle valve

Needle valves and shutoff valves are almost similar but designed differently. They are used to start, stop, and control the flow rate of a pipeline. As opposed to a cut-off valve, a needle valve has a long, tapered, needle-like tip at the end of the valve stem. This is commonly known as the plunger.

These valves also include a handwheel or a tiny lever on the plunger that regulates the plunger position. The needle-like plunger of the valve inserts into the seat. Because of its unique shape, a needle valve can precisely and reliably control the amount of fluid that goes through it

How does needle valve works

The operation of needle valves can be done manually or mechanically. The distance between the plunger and the valve seat is controlled by the handwheel in manually operated needle valves.

The plunger is lifted when the handwheel is moved in one direction, opening the valve, and allowing fluid to pass through. The plunger travels closer to the seat when the handwheel is moved in the opposite direction, reducing the flow rate, or closing the valve.

 Automated needle valves have a hydraulic motor or an air actuator that opens and shut the valve automatically. The motor or actuator will adjust the plunger’s position in response to timers or pre-set data obtained while monitoring the machinery.

Needle Valve Selection Guide

  1. For the main pipeline of oil and natural gas transportation, the needle valve with full diameter and full welding structure shall be selected for the pipeline that needs to be cleaned and buried underground;
  2. The needle valve with flange connection is selected for the product oil transmission pipeline and storage equipment.
  3. In the pipeline of city gas and natural gas, the needle valve with flange connection and female thread connection is selected.
  4. In the oxygen pipeline system in the metallurgical system, the needle valve with strict degreasing treatment and flange connection should be selected.
  5. The low-temperature needle valve with valve cover should be selected for the pipeline system and device of low-temperature medium.
  6. Lifting rod needle valve can be used in pipeline system of FCC unit in oil refining unit.
  7. All stainless steel needle valve made of austenitic stainless steel with PTFE as seat sealing ring should be used in the equipment and piping system of corrosive medium such as acid and alkali in chemical system.
  8. Metal to metal sealing needle valve can be used in high temperature medium pipeline system or device in metallurgical system, power system, petrochemical plant and urban heating system.
  9. When flow adjustment is needed, worm gear driven, pneumatic or electric needle valve with V-shaped opening can be selected.
