Product Description

Application

RA series safety valve is the sanitary stainless steel valve,its safety design make it protect the equipment,so it installed  in the return circuit of discharge pressure,it's good for safety protect function in pipeline ,pump ,device,storage tank.This valve extensively use to food ,beverage,dairy,beer etc.

Working Principle

RA series safety valve is calibration one specific pressure by adjust gland nut.calibration pressure is the max.safety pressure in order to avoid equipment damage.Under the normal working pressure,the valve is close:When the pressure of system beyond the calibration pressure,the valve will be open .The pressure in the pipeline system get release,thus protect the pipeline and equipment.
RA11 series valve is the improve type of RA,it add the start and open device,it is easy to doing CIP cleaning for safety is a little special valve,it through strict calibration before leave factory ,but if have conditional ,should be calibration the valve again in locate as far as possible.
