What You Must Know About Needle Valve

As with most other valves, high-quality needle valves are responsible for the efficient and safe operation of various commercial machinery and equipment. They are made to take care of the fluid flow rate passing through a pipeline. So, you might wonder how it works now. We've created this blog to help you with that question. Continue reading to learn more about needle valves, which will also be helpful if you intend to buy a block and bleed needle valve online.



Construction and Design

Such valves operate in a manner similar to the shut-off valves. Within a pipes system, they are used to start, stop, and also control the flow rate. The operation may be similar, but needle valves are designed differently. Contrary to those shut-off, the needle valves are longer at the endpoint of the stem and are equipped with a needle-like point (thus the name). Mostly, this is known as the plunger.

Working 

The needle valves can work in two different ways: manual and automatic. Manually operated needle valves use a hand wheel to regulate the distance between the plunger and the valve seat. On the other side, automated needle valves are attached to an air actuator or a hydraulic motor, which automatically opens and closes the valve. The operation differs, but both offer accurate control over the flow rate.

In case you are looking to purchase a high-quality multiport needle valve for your specific industrial requirements, you must try searching for it online. Visit websites of different suppliers and you can easily get an affordable deal.

3 Interesting Applications of Pressure Transmitters

Pressure transmitters are widely used across various process industries to measure pressure of liquids, gases and fluids. Additionally, they are also referred to as pressure transducers. These devices are capable of doing much more than just checking the pressure of an equipment or machine. Over the course of time, numerous process companies have figured out some interesting uses of pressure transmitters, which we are going to discuss in the next part of the blog. Level Measurement Applications — This is regarded as one of the most fascinating uses of pressure transducers. The sensors fitted to the transmitter can be used to accurately measure the level of liquid present in a container. If someone is using a pressure transmitter for the purpose of level measurement, you must acknowledge the fact that you need to know the precise capacity of the container, and also the specific fluid gravity. Flow Measurement — There are numerous flow measurement equipment that can be used to
