Variation of floating ball design
• Ball is fixed against
the seats with springs
that apply pressure
• Springs are sensitive
to pressure
Belleville
Spring
Washers
Flow
• Pressure may not be
evenly applied,
resulting in leaks
Seat
• Springs may corrode

 Adjust-O-Seal®

maintains bi-directional
sealing using force of

seats to the ball

• Allows for upstream sealing on 2-way valves
• Allows flush tank valves to seal on upstream (top) seat
• Provides positive sealing on 3-, 4-, and 5-way valves
• Creates a “dual chamber” that allows optional cleaning
or steaming of valve internals while providing complete
isolation from the process -- when the valve is in the
full closed or full open position.

PACKING
Bellville washers compensate
for normal wear by providing a
constant load on the stem seal
23
• Stem becomes integral part
of actuator drive shaft
• Eliminates problems caused
by uneven bolting
• Prevents side-loading and
premature or uneven stem
packing wear
• Increases cycling life
