Clark-Reliance has announced Jerguson 360 series safety ball check valves that are said to greatly improve the safety and reliability of traditional-style safety ball check valves by eliminating the potential of false level indication during commissioning.

A unique quarter-turn position visible handle allows the operator to easily see the valve’s mode of operation (run, closed or bypass). When commissioning a level gage assembly, the operator simply turns the handle of the valve to the bypass position.

In this scenario, the ball check cannot seat because the ball check seating surface is upstream of the ball. Fluid will flow around the ball, through a retainer plate, and into the gage. When the fluid stops rising, the handles are turned to the run position.

The run position is intended for when the gage is in normal operation. The handles can also be positioned to closed mode when it is necessary to isolate the gage from the vessel. This will prevent fluid from entering the gage or draining back to the vessel.

Each valve is equipped with a locking pin and lock-out tag-out slot to enhance plant safety. As a standard these valves are low emission certified to API 641 and ISO 15848-1.

Valves meet API Class V shutoff requirements and have wetted components that comply with NACE MR0103 and MR0175.
