~Ypattern diaphragm valve Introduction
■Ypattern diaphragm valve Features:
1.Ypattern diaphragm valve adopts dual control chamber design, to control the internal water flow, so that the control function is more flexible, reliable and durable, totally eliminates the switching defects that single chamber might have.
2.Y pattern diaphragm valve body and valve bonnet is made from fiberglass reinforced NORYL material, high strength, long service life and corrosion resistant.
3.The reinforced rubber diaphragm is molded by special treatment, long service life, and high strength.
4.Y shape flow channel design reduces pressure loss, increases water flux.
5.Flexible conversion between normally-open type and normally-closed type.
6.spring assisting, water flow restriction and operation display are available also.

■Y attern diaphragm valve Operation principle
valve Close:
Control signal (either water pressure or air pressure, should higher than inlet water pressure) led to diaphragm upper control chamber, valve stem push valve to close inlet water.
valve Open:
signal Pressure is relieved from upper control chamber, inlet water pressure push up valve stem, easy to form a open channel, and let liquid flow through.
