Advantages: Necked flat welding flanges are also classified as flat welding flanges, as they have a short neck, which improves the strength of the flange and improves its load-bearing capacity. So it can be used on higher pressure official roads. Disadvantages: Compared to plate type flat welding flanges, they have a higher cost and are more prone 1
The self operated pressure regulating valve series products have three structures: single seat (ZZYP), sleeve (ZZYM), double (ZZYN), and so on; There are two types of actuators: membrane type and piston type; There are two types of functions: pressure regulation after the valve for pressure reduction (Type B) and pressure regulation before the valv1
Knife gate valve, also known as knife gate valve, knife gate gate valve, slurry valve, and mud valve, has a gate as its opening and closing component. The direction of movement of the gate is perpendicular to the direction of the fluid, and the medium is cut off by a blade shaped gate that can cut fiber materials. The gate has two sealing surfaces,1
This series of proportional pressure reducing valves is a regulating valve that proportionally reduces the pressure of the medium flowing through it. It utilizes the pressure generated by the different cross-sectional areas of the piston at both ends inside the valve body to change the pressure behind the valve and achieve the purpose of reducing p1
Product Overview: The flange gate valve is widely used as the opening and closing device for connecting or cutting off the medium in the oil and steam pipelines of petrochemical industry, Fossil fuel power station, etc. Product features: 1. Compact structure, reasonable design, good valve rigidity, smooth channel, and low flow coefficient 2. The se1
Cast steel electric ball valves are suitable for two-position cut-off and adjustment situations. The connection between the valve and the actuator adopts a direct connection method. The electric actuator is equipped with a built-in servo system, without the need for an additional servo amplifier. The operation can be controlled by inputting a 4-20m1
The fully lined rubber and fluorine lined flange butterfly valve has a simple structure, small volume, and light weight, and is only composed of a few parts. Moreover, the valve can be quickly opened and closed by rotating it 90 °, with simple operation and excellent fluid control characteristics. When the butterfly valve is in the fully open posit1
Product Usage The PZ973H electric knife gate valve series products are widely used in various industrial fields, especially in mining and steel industries - used for coal, filter slurry, purification devices - used for wastewater, mud, dirt, and clarified water with suspended solids, paper industry - used for any concentration of pulp, feed water m1
