INTRODUCTION
Donjoy specializes in manufacturing and exporting valve,pump,fitting for over 20 years with good quality and pretty competitive price. Products are with 3A,CE,FDA cetification and production management is according to ISO9001-2008.
APPLICATION
V-type (inlet constant pressure),maintain constant pressure at the valve inlet, Such design is specially applied
at the back of heat-exchager,it is used as safety valve.
A-type (outlet constant pressure),maintain constant pressure at the outlet,Such design is used as the front of filling machine and bottle filling machine.
OPERATING PRINCIPLE
Constant pressure valve operated by compressed air, automatically run without sensor on piping system or
other auxiliary instruments,and only one compressed air pressure regulating valve that maintains pressure stability can be realized the normal work on the valve.
Diaphragm slice and valve rod can be fit to transport product any pressure changes to make a quick respones.
and the corresponding change the valve stem position, in order to continue to keep the preset pressure valve.
