DESCRIPTION

Everlasting Boiler Blowdown Valve, 2 in, FNPT, 250 LB Class, Quick Opening, Series 4000-A, Cast Iron Body, Lever Actuator
Line pressure and heavy spring hold disc firmly against the body seat, sealing off the flow. When the Everlasting Quick Opening Blow Down Valve operates, the disc slides across the body seat pushing harmful boiler scale away, and wiping clean the precision lapped surface. Hand adjustment of the post packing is eliminated. Post packing is self-adjusted by a spring and line pressure. This prevents destructive erosion and leakage of stuffing box.
