This panel mountable, two-piece design is available in globe and angle patterns for fl exibility of installation. Dyna-Pak packing provides leak-tight sealing with low operating torque. Optional Graph-Lock packing is available for high-temperature applications. The safety back-seating prevents accidental removal of the stem.
