DI CI SS304 SS316 Butterfly Valve Body
The valve body is the most basic, one of the most important parts of the valve, choose the right material for the valve body is very important. We ZFA Valve has many different model of valve body to meet your require. For valve body, according to the medium, we can choose Cast Iron, Ductile Iron, and we also have stainless steel valve body, such SS304,SS316. Cast iron can be used for media that are not corrosive. And SS303 and SS316 weak acids and alkaline media can be selected from SS304 and SS316.The price of stainless steel is higher that cast iron.

Butterfly Check Valve with Heavy Hammer
Butterfly check valve are widely used in water, waste water and sea water. According to the medium and temperature, we can choose different material. Such as CI, DI, WCB, SS304, SS316, 2205, 2507, Bronze, Aluminium. The micro-resistance slow-closing check valve not only prevents the back flow of media, but also effectively limits destructive water hammer and ensures the safety of pipeline use.
