When working with air compressors and air tools, airflow is crucial. The same goes for controlling airflow when operating your machine. The working process is effective with the right Valve Airflow Control item. There are many types of airflow control valves you can find, and one of which is the needle valve. However, choosing the right needle valve for your application should not be random and needs detailed attention. As it may affect your working process, it is only necessary to follow a guide that discusses factors for the best needle valve airflow control.
Using Needle Valve As Airflow Control: How It Works
Like any other valves, using needle valves as airflow control helps maintain a safe and efficient work. Needle Valve Airflow Control manages the movement flows of fluids and gas. For a reliable shut-off valve, the needle valve is also useful.
The needle valve airflow control may be automatically run or manually. The manual needle valve has a handwheel that controls the gap amid the plunger and seat. The handwheel turn directions guide whether to lift the plunger and enable the fluid to run through or drive the plunger closer to the valve seat and reduce the flow rate up to shut the valve. On the other hand, an automatic needle valve, from the name itself, opens and seals the valve automatically. The plunger position may be automatically adjusted according to the timer set when operating the machine or system.
Guide to Right Needle Valve Airflow Control Selection
Once you have decided the type of airflow control valve you need, picking the right one requires consideration. As for the needle valve airflow control and its function, finding the best one is necessary. It will ensure you can achieve the same outstanding purpose and have a smooth working process managing your machine. Before buying one, additional research and a better understanding of the valve is a helpful guide.
Some factors can help you land on the right one and set a budget for an airflow control valve price. These include material, pressure, size, and temperature that plays a crucial role in every needle valve. To help you with your purchase, here are the detailed factors and guide for the right needle valve selection:
Needle Valve Material: Brass or Stainless Steel?
Choosing a needle valve is also not a guessing game. To ensure the right housing material for your needle valve, understanding your application must come first. There are many housing valve material designs for specific applications. However, chemical endurance materials in brass and stainless steel are common housing materials for needle valves. Those valves in brass material are fit for high applications, hydraulic systems, or drinking water applications. On the other hand, stainless steel needle valves are suitable for almost any applications as it is durable. It can also manage even if the temperature and pressure are high.
Another factor that needs consideration is the pressure specification for your application. It is vital when choosing the right needle valve to use. If you are dealing with an application that requires high pressure, then a valve that can withstand the requirements is needed. There are also vacuum needle valves specifically designed to cater applications that need low pressure.
The Sizes of Needle Valve Ports & Orifices
Aside from material and pressure application, the sizes of needle valve ports and orifices also matter. It comes in different sizes, and finding the needle valve that fits your application will ensure the flow rate and operation is efficient. Flow rate is vital in operating your machine, and understanding what size of the needle valve you need is necessary. Its ports come with male and female ends and follow the NPT or National American Pipe Thread, ISO, and BSP metric standards.
Temperature also plays a vital role when working with your machine. To ensure an efficient work operation, a needle valve that can handle whether your application requires low or high temperature is needed. The temperature factor is also your guide to choosing the right sealing and housing material for the needle valve. Making sure that your needle valve can handle and withstand extreme temperatures secures a well-running operation.
