✧ Description

Forged steel globe valve is a high-performance valve, widely used in chemical industry, petroleum, natural gas, metallurgy, electric power and other industries. The forged steel globe valve adopts a fully welded structure, and the valve body and gate are made of forged steel parts. The valve has good sealing performance, strong corrosion resistance and long service life. Its structure is simple, small in size, easy to install and maintain. The gate switch is flexible and can completely cut off the medium flow without leakage. The forged steel globe valve has a wide temperature range and high working pressure, and can be used for medium flow control under high temperature and high pressure and low temperature and high pressure conditions.

✧ Features of Forged Steel Globe Valve Bolted Bonnet

1.It is easier to make and maintain due to its simpler structure than a globe valve.
2.The sealing performance is good and the sealing surface is resistant to wear and scratches. When the valve is opened and closed, there is no relative sliding between the sealing surface of the valve body and the valve disc. As a result, there is little wear and tear, strong sealing performance, and a long service life.
3.Because the stop valve's disc stroke is modest when it opens and closes, its height is less than that of the globe valve, but its structural length is longer.
4.The opening and closing process requires a lot of work, a huge torque, and a lengthy opening and shutting time.
5.The fluid resistance is high due to the valve body's curved medium channel, which also contributes to the high power consumption.
6.Medium direction of flow In general, forward flow occurs when the nominal pressure (PN) is less than 16 MPa, with the medium flowing upward from the bottom of the valve disc. Counter flow occurs when the nominal pressure (PN) exceeds 20 MPa, with the medium flowing downward from the top of the valve disc. to improve the seal's functionality. The globe valve media can only flow in one direction while it is in use, and it cannot be adjusted.
7.When the disc is fully open, it frequently erodes.

✧ Advantages of API 602 forged steel globe valve

During the opening and closing process of the forged steel globe valve, because the friction between the disc and the sealing surface of the valve body is smaller than that of the globe valve, it is wear-resistant.
The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for the adjustment of the flow rate. Therefore, this type of valve is very suitable for cut-off or regulation and throttling.
