250°F (121°C) max with UHMWPE stem packing.
450°F (232°C) max with PTFE stem tip (NTR) or stem packing.
600°F (315°C) max with PEEK stem packing and 316 SS, 316/316L SSD, alloy 20, alloy 600, alloy C-276, or titanium
500°F (260°C) max with PEEK stem packing and alloy 400 (alloy 400 available in N series only).
1000°F (537°C) max with 316/316L SSD body, bonnet and stem components.
Testing of Needle Valve
Each set of HI-TEK threaded Needle Valve has been tested in the factory with nitrogen at 1000Psig (69bar), and the maximum allowable leakage rate of the valve is 0.1 standard cm³/m in. The shell test is based on the use of leak detection fluid, and there is no detectable leak.
Note: Packing may need to be adjusted during the service life of the valve. Valves that have not been opened for a period of time will have a higher initial force torque.
