The Type T valve 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
