Type T is the caged equivalent to the Type A valve. The use of this FRI-tested valve precedes the Type A valve.
- The Type T valve has a single moving cap with no moving legs protruding through the deck.
- A cage assembly retains the cap.
- It is more resistant to weeping and to becoming dislodged from the deck.
- It is more fouling resistant than the Type A valve.
- It normally comes dimpled, but can be flush seated as necessary.
Equivalent BALLAST® designation: A-2.
