First, detailed materials of the product [the diaphragm valve ]:

Name of product: Manual diaphragm valve

Characteristic of the products: The lack of mutual understanding valve is that a kind of special shape worker has valves which blocks the function, it opens and close one by steel one and soft material (whether rubber and fluoroplastics compound), lack of mutual understanding that make make up and separate by achieving the goal of blocking medium while managing in covering with valve valve body.

Design specification: Follow GB 1239, BS 5156 standard.
Drive way: Manual , pneumatic (often open or often close ) , electronic.
The flange joins the diaphragm valve
It accords with China's national standard to design and make
Basic structure form : The weir type, direct current type
Nominal pressure PN0.6 common 1.0 (Mpa)
Nominal Yes DN15-400 directly (mm)
