How Figure 4000 Series Operates:

Line pressure and heavy spring hold disc firmly against the body sea, sealing off the flow. When operated, the disc slides across the body seat pushing harmful boiler scale away, and wiping clean the precision lapped surfaces.

Hand adjustment of the post packing is eliminated. Post packing is self-adjusted by a spring and line pressure. This prevent destructive erosion and leakage of stuffing box.
