FQA:
1.What is the difference between A105 and WCB in valve material?
1). Different materials
Carbon steel for A105 valve refers to a series of forged steel in ASTM A105 standard, and the material used is forged Bai steel. The carbon steel for WCB valve refers to WCB and WCC cast steel in ASTM A216 standard, and the material used is cast steel.
2). Different molding methods
A105 valve using plastic deformation, forging workpiece can improve the internal structure, good mechanical properties, uniform grain. WCB valve is formed in liquid state, which will cause structural segregation and defects. Of course, casting has its advantages. It is difficult to open the mold when forging complex parts, so casting has been adopted.
3). Different performance
The quality of A105 valve forging steel is higher than that of steel casting, which can withstand large impact force, and the mechanical properties of plasticity, toughness and other aspects are also higher than that of WCB steel casting. Therefore, forging steel should be used for all important machine parts.
2.What are the structural characteristics of swing check valve?
There are 9 structural features of swing check valve
1). The length of the structure is short, which is only 1 / 8~ 1 / 4 of that of the traditional flange check valve
2). Small size, light weight, its weight is only 1 / 20 ~ 1 / 4 of the traditional flange check valve
3). The valve disc closes quickly and the water hammer pressure is small
4). Horizontal or vertical pipe can be used, easy to install
5). The flow channel is smooth and the fluid resistance is small
6). Good sealing performance, sensitive action
7). The disc stroke is short and the valve closing impact is small
8). Overall structure, simple and compact, beautiful shape
9). Long service life and high reliability
Our outstanding advantage is our ability to provide users with high-quality Cast Iron Wafer Check Valve and comprehensive and excellent services. We have always adhered to the corporate philosophy of making ideas come true and the corporate culture of diversity, tolerance and innovation.
