High-Temperature Threaded Precision Flow-Adjustment Valves
- Valve Type: Needle
- For Use With: Water, Oil, Air, Steam
Rated for nearly twice the maximum temperature of standard threaded precision flow-adjustment valves, these can handle up to 700° F. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Body is 316 stainless steel for excellent corrosion resistance. Valves have metal-to-metal seats that resist temperature fluctuations. All have a nut that can be tightened to compress the packing if it leaks.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
