The Industrial valve is a kind of necessary element inside of pneumatic actuator and its function is to control the current passing through. Therefore, it is necessary to figure out some ways to prolong the industrial valve and pneumatic actuators lifespan.
The Industrial valve is the general name of several valves such as ball valve, plug valve as well as butterfly valve. And it is a kind of component for devices like electric actuator or pneumatic actuator. Due to the presence of new technology, the Industrial valve is able to possess higher performance and wider applications.
The American Petroleum Institute has released its newest valve standard as part of the industry’s continuous efforts to improve operational safety and environmental protection. Specification 6A governs the design and operations of the critical safety valves at wells used in the offshore and onshore
The Industrial valve is the necessary control and adjustment part inside of pneumatic actuators, and in order to make sure the normal running of the Industrial valve, it is necessary to lay emphasis on the Industrial valve maintenance period.
The Industrial valve is a crucial component of electric actuator. It is used to connect two pipelines and control the fluid. Although having some problems in technology, the Industrial valve still has its own application due to the advantages and wide functions.
Low-pressure casting is to inject the molten metal into the sealed electric resistance furnace. The mold (usually of the metal type) is placed on the sealing cap, and the vertical riser allows the molten metal to communicate with the gate that faces downward. The mold is horizontally divided, and the metal type must be preheated before spraying and sprayed with paint.
The correct operation of the safety valve is very important, so what are the aspects that need to be paid attention to when installing, using and maintaining the safety valve?
Principles of selecting gate valve, the gate valve should be the first choice when shut-off valves need to be used for pipelines. Normally, globe valves are a little bit expensive than gate valves, but a little cheaper than metal-sealed ball valves, seldom used as shut-off valves for main pipelines.
China has produced and applied cast iron valves for nearly 100 years, but significant development has been the case in the last 10 years. According to relevant statistics, the annual output of domestic cast iron valves and fittings has increased from 800,000 tons to 2,000,000 tons in the past 10 years, with an average annual decline rate of about 20%.
Common manual valves, including ball valve, gate valve, globe valve, butterfly valve, plug valve, etc., are the most widely used valves. Their handwheels or handles are designed according to ordinary manpower, taking into account the strength of the sealing surface and the required closing force.
