Matco Norca have upgraded the Press Ball Valve to feature leak prior to press technology. This new design incorporates a special EPDM o-ring that will allow water or air past the sealing element of any unpressed connection.
In any press-fit application, the main difference between water and gas fittings is the o-ring seal. The seal is the important part in this system. In order to get the highest safety level and durability, different o-rings are used for different applications. Each o-ring has different properties that make it most suitable for the application. Matco-Norca Press Ball Valves have an EPDM water o-ring, designed for use with potable water.
Matco-Norca Press Ball Valves have a new feature that provides quick feedback, identifying any unpressed connection during the pressure testing process.
This feature is built into the design of the ball valves o-ring and provides a path for liquids from inside the pipe to weep past the sealing o-ring of an unpressed connection. When testing with water the proper pressure range is 15 to 85 psi maximum. Matco Norca does not recommend pressure testing with air as it can be extremely dangerous at high pressures.
