Working pressure in psig(bar)Pressure up to 6000 psig(414 bar) for stainless steel

Pressure up to 3000 psig(207 bar) for brass

Temperature for PTFE packing from -65oF to 450oF(-54oC to 232oC)

Temperature for Grafoil packing from -65oF to 1200oF(-54oC to 649oC)

Packing below stem thread isolates the thread lubricants from the media

PTFE ring in the gland protects stem thread from outside contamination

Non-rotating stem tip

Optional mounting holes at the bottom of the body

Every valve is factory tested at or above 1000 psig(69 bar) with nitrogen, 3%

valves have another test at 1.5 times maximum working pressure with pure water
