Sanitary Pneumatic Reversing Seat Regulating Valve with Controller
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
Lift type mixing proof valve is remotely operated through compressed air,it's normally closed before running.The
