sanitary pneumatic( manual ) safety / relief valve
HS Code:84818010
TECHNICAL PARAMETER:
Application:
The valves are used in automation and contronl systems to control the pressure, flow, level,t emperature and the tank level.
Working principle:
This sery safety valve is to adjust the spring compression nut to calibrate a particular pressure .The calibration of pressure is to fix the maximum pressure to avoid the quipement damage .In the normal working operating pressure ,the valve is closed ;when the system pressure exceeds the calibrated pressure ,the valve is closed ;whne the system presure exceeds the calibrated pressure ,the valve is open .The pressure in the piping system being released ,so as to protect the pipe system and the equipment .The valve is with start the open device for the CIP cleaning of the safety valve and the piping .
The safety valve is a special valve through a rigorous calibration,but to make the valve more realistic operating conditions,so the conditions should be as much as possible the scene of the valve and then parity .
Advantages :
with simple structure,good shape ,fast to adjust the pressure ,easy to maintenance
Pressure contronl is adjustable ,and can be adjusted in the safety range .
The valve body made of stainless steel can bear acid ,the surface is bright and clean ,the sealing made of food rubber ,comply with the sanitary regulations.
When install,we can not reverse the flow of fluid input .
Material:
material contact Steel parts: Stainless 304\316L
valve core seal selection:a)soft seal: EPDM. (standard)
SILICON,FDM, HNBR(CHOOSE).
b)metal seal
