EFFECT of VENTIDUCT

Ventiduct provides the following protection:

・  The "VENTIDUCT" option protects the metal parts of the solenoid from any volatile corrosive gases (such as TRIFLUORO ACETIC ACID) that manage to pass through the diaphragm. It is also available with a "Backup Diaphragm" to further increase the protection provided.

・  VENTIDUCT protects the fluid from heat generated in the solenoid.

・  VENTIDUCT shields the solenoid when the valve is used to control high temperature fluids.

TEST 1
The effectiveness of VENTIDUCT when protecting metal parts from gaseous TRIFLUORO ACETIC ACID

Test Conditions
Diaphragm: PTFE, 0.2mm thick
Time: 48 hours
Plunger: ME1F
Ambient Temp.: Room Temp.
Fluid: Trifluoro Acetic Acid
Without Backup Diaphragm

                             

Sample A (without Ventiduct) - Sample B (with Ventiduct)

WITHOUT VENTIDUCT: Corroded by Trifluoro Acetic acid that passed through the diaphram
