Diaphragm Valve
Good Quality Y -Type pneumatic Diaphragm Valve Hydrodynamic Diaphragm Valve
Products Features
Adopt upper and lower double chamber design, control water flow independently of the flow body chamber, through the upper and lower two pressure source end, flexible control valve switch, randomly realize normally open or normally closed. For the choice of pressure source is also more diverse, can be hydraulic, can also be pneumatic.
What is the advantage of Y type diaphragm valve?
● Enhanced engineering plastics manufacturing, durable.
● Y-type diaphragm valve adopts the upper and lower double control chamber design. It control water flow independently of the flow body chamber, thus making the valve control more flexible, reliable and durable. It completely eliminated the single-chamber control valves may exist in the switching malfunction, the hidden danger of laxity.
● The valve body and bonnet are made of glass fiber reinforced NORYL material. the valve has high strength, long service life and corrosion resistance.
● Special treatment of molded reinforced rubber diaphragm sheet, long service life, high fatigue strength.
● Y-shaped fluid passage design reduces the pressure loss of the valve and improves the water flux.
● Normally open and normally closed types can be easily and flexibly converted.
● Functions such as spring-assisted opening (closing), flow limitation or switching display can be added.
How does Y type diaphragm valve work?
● Close the valve:
the control pressure source (water or gas source, pressure equal to or greater than the pressure of the incoming water) is led to the control chamber on the diaphragm, and the diaphragm pushes the valve seat through the valve stem, thus cutting off the incoming water to close the valve;
● Opening the valve:
when the pressure in the upper chamber of the diaphragm is relieved, the incoming water pushes open the valve stem through its own pressure, thus easily forming a through chamber for the fluid to pass through.
