Understanding Using Brass Needle Valves to Control Gas or Liquid Flow

If you need more precise valves to control liquid or gas distribution, you should consider using needle valves. These valves are a perfect solution for a task requiring careful resistance in a non-viscous system.

Needle valves are designed to control many different mediums as they offer excellent flow control. Read on to learn everything you need to know about brass valves.

How Needle Valves Work

Brass needle valves, like most other valves, are used to guarantee the efficient and safe operation of heavy-duty machinery and the liquid or gas used in the process. These valves control the rate of fluid flowing through a pipeline.

Similar to shut off valves, needle valves can be used to stop, start, and regulate the flow of gas or liquid. As needle valves are designed with tapered, needle-like points at the end of their valve stem, they offer better control over the rate of flow.

While not all needle valves are the same, both automatic and manual needle valves have a handwheel that controls the distance between the valve seat and plunger. Once the handwheel is turned in a specific direction, the plunger lifts and opens the valve, allowing the fluid to go through.

Using a Needle Valve

Brass needle valves have many different uses. However, they are commonly used for protecting delicate gauges from the sudden damage caused by surges of gases or liquids.

Needle valves are ideal for a system that uses less vicious and light materials as they have low flow rates. Oftentimes, these valves are used in chemical processing, low-pressure hydraulic systems, and similar liquid and gas services.
