As an actuators and valves company, COVNA has always been committed to providing sustainable flow solutions for various industries, including wastewater treatment, shipbuilding, and power plants.
At present, due to the development of science and technology, the demand for electricity is increasing, which has led to an increase in the demand for valves in power plants.
In this article, we will briefly introduce you to valves used in power plants, hoping to help you make better choices.
Gate Valves
The gate valve is used for transport or shut-off. The gate valve can only be fully open or fully closed, so it is not suitable for regulating. According to the design, the gate valve can be divided into rising stem gate valve and non-rising stem gate valve. More importantly, if the medium is thicker, the knife gate valve is recommended to avoid clogging, which will affect the normal operation of the project.
Available in manual type and automated type.
Globe Valves
The globe valve and the gate valve both belong to the isolation valve, the difference is that the globe valve can adjust the flow according to your needs. The globe valve is simple in design, easy to maintain, and has a long service life. Available in electrically type, pneumatically type and manual type.
Ball Valves
The ball valve is a quarter-turn valve. There is a hollow ball inside, which can transport or shut off the medium as the valve stem rotates 90 degrees. Since power plants will require high temperature or high pressure, the metal seat trunnion-mounted ball valve will be more suitable. For the requirements of normal temperature and pressure, a 2-piece or 3-piece ball valve could help you to control the flow rate, and the cost is low.
We could offer electric actuated ball valve, pneumatic actuated ball valve and manual ball valve for your options.
Butterfly Valves
Butterfly valves and ball valves are both quarter-turn valves. The butterfly valve has a disc that rotates 90 degrees around the valve stem to open or close the valve. The butterfly valve is easy to install, easy to maintain and saves installation space. For power plants, we would recommend high-performance butterfly valves. Because it adopts a metal seal and metal valve seat, it can withstand high temperature and high pressure well. For the needs of normal temperature and pressure, we would recommend soft-sealed butterfly valves. Its advantages are cheap and deliver more cost-effective solutions. We could provide actuated butterfly valve and manual butterfly valve for your power plant.
Check Valves(Non-Return Valves)
Check valves are used to prevent backflow. This means that the check valve only allows one-way flow. It can protect the entire pipeline system and equipment from damage and ensure the normal operation of the system. According to the design, check valves can be divided into wafer type, swing type, spring type, double door type, flap type, etc., to meet your different industry needs.
Industrial valves in power plants often need to withstand high pressures and high temperatures, so it is very important to choose cooperative valves.
