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.As a seasoned producer and exporter of forged steel valves, we guarantee to offer our clients first-rate post-purchase support, which includes the following: 1.

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.| Product | Forged Steel Globe Valve Bolted Bonnet |
