- Original Designs
Takasago's VENTIDUCT is an optional part which is fitted between a valve body and the solenoid. It has ducts for ventilation and heat radiation. It is used as follows.
・With volatile and corrosive fluids
・With fluids which are temperature sensitive
・By users of high temperature fluids
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.
