Giacomini A61 Test Drain Valve features
Giacomini A61 Test Drain Valve is used in fire installations, sprinkler lines, to perform testing operations in installations with the same orifice diameter as the k factor of the smallest orifice sprinkler, and in maintenance work.
There is an observation glass on the venturi created by the water flow in the oropharynx of the test drainage valve. One of the biggest advantages of the test drainage valve is that it can both test and drain the line with a single valve.
In determining the test drain valve size, in addition to looking at the line diameter, the orifice diameter should have the same orifice diameter as the sprinkler models in the line.
The internal threaded Test Drain Valve is made of forged brass and has NPT internal threaded inlet and outlet. It is a valve with teflon seal and brass ball.
