Jerguson® 360 Series Metal Seated Safety Ballcheck Valves

Innovative Core Design Locating an Internal Ballcheck within a Metal Seated Valve. All 360 Valves now include a color indicator ring as standard. The high visibility of this indicator ring will confirm your valve status from a glance!

Red = Isolation of Gage from Vessel

The Jerguson 360 Series valve is equipped with many features that elevate its performance above traditional style safety ballcheck valves. Designed to alleviate a widespread problem, the 360 Series’ bypass mode seeks to remove guess work or operator error during commissioning. The quarter turn position — visible handle provides clear operation status and a locking pin to secure its position.

As opposed to traditional ballcheck valves, it is impossible to get a false level reading with a 360 Series valve during commissioning.  When using a traditional ballcheck valve and commissioning a gage assembly when there is already liquid present in the vessel, it is common for the operator to open the valve too quickly, causing the ballcheck to engage and the level gage to display a false level reading!  That problem is eliminated with the 360 Series valve. The video below demonstrates the simplified commissioning procedure of the 360 Series valve.




Jerguson Safety Ballcheck Valves are an essential component of a glass level gage assembly.  In addition to isolation, Safety Ballcheck Valves provide an automatic shut-off for glass level gage products in the event of a catastrophic glass or gasket failure.

With liquid present in the
vessel, open the top valve
to By-Pass position.

Then open the bottom valve to
the bypass position. Fluid will
now flow through the valve and
into the glass without seating
the ballcheck.

Once the level stops rising, move both valves to the run position. Now, the valves are ready for normal operation. If your level gage is not maintained properly or a leak occurs, the ballcheck will engage and isolate the gage from the vessel.
