Description
Rubber PRV Ball
The rubber PRV balls help fireproofers and other sprayers to know when pressure has exceeded certain limits in the manifold. The red pressure relief ball, found circling the manifold , withstands pressure within the manifold up to 1000 psi while the green PRV ball goes to 700 psi. Both the red and green balls are sold at the same price.
Before the use of the red and green PRV balls, sprayers used the black prv ball.
