Features/Applications
Features
Quick startup
Automatically discharges initial air and cold condensate.
Condensate recovery
With its high degree of back pressure tolerance, this model supports condensate recovery.
High discharge capacity
A double ported balance valve provides a large discharge capacity in comparison with single valve models.

●This product uses a double ported balance valve system so if the actual condensate volume is significantly lower than the product’s discharge capacity, there may be a steam leak.
Discharge Capacity
