Valve is a multifunction device that can be used for almost every purpose. There are many types of valve available out there to select. Either it is butterfly or ball valve, all the types of valves have their own functions and specialties. One of the valve’s types is used by a lot of people is the needle valve. This kind of valve can give benefits for the users in many ways, include digging in the dirt for water recycling and conservation purposes. To give you clearer description of how this type of valve will work for you to dig in the dirt, here are all things you need to know about it.
What Is Needle Valve?
A needle valve is a type of valve with needle – shaped plunger. The device has a threaded and small port attached to it. This type of valve is designed to make it possible for the device to get precise regulation of the liquid’s flow. But the device comes with only relatively low rate of flow that will not suitable for large scale of usage. In using the valve, you have to make sure that the device is completely opened or closed due to the low rate of flow. The needle valve is commonly found in the applications of flow – metering with a calibrated and constant flow rate in particular. The device is completed with a spindle that functions to control the flow of the fluids. The size of this type of valve is relatively small that makes it easier to transport. Just like the other types of valve, the needle valve is also made of stainless steel, titanium, brass, PVC, chrome, CPVC, PFA-lined, and many more. But just to keep in mind to avoid picking up the one made of brass since it is easy to damage. This is because the device can’t bear the excessive turning force when it comes for the valve to prevent the flow of the liquid.
Selection Criteria of Valve to Improve SAGD
In order to provide clean water and conserve it, the SAGD uses needle valves to dig in the dirt. The device is applied by slurring the bitumen and water. The quality of water resulted is also influenced by the choosing of technology used in the process. The selection of the device considers the safety, capital cost, as well as the plant reliability. The material construction of the valve as well as the design also determines the device’s resistance. Here are some criteria of the valve selection you should know:
- Make sure that all the sealing members of the valve are hard-faced.
- Picking up a full – port valve that can streamline erosion and turbulence.
- To decrease the seat water, you can choose valve seats which are not the path of the flow.
- The coating on the valve must be applied through the parts of the body flow.
