Self Compensating Valve Stem Seal Design Ensures Long, Leak-Tight Maintenance Free Service
Full Thread Length Compliance with ANSI B1.20.1 Specification Allows More Flexibility in L1 (hand) and L3 (wrench) Pipe Makeup for Handle Orientation and or Positive Sealing with Lesser Quality Mating Pipe Threads
Machined Reinforced PTFE Seats and Stem Seal Standard for Uniform Operating Torque and Long Life
Bar Stock Construction Offers Optimum Material Strength and Consistency
The BV80 series has been discontinued. Please contact our Flow Engineering department.
The BV80 Series is a standard port, two-piece body offered in 1/4 thru 2" pipe size.
Proper valve selection is dependent on your flow and functional requirements as well
as physical size and value considerations.
The BV80 Series, all internal components, including the polymer seats, are precisely
machined to strict tolerances, assuring repeated bubble tight sealing and maximum
valve life. Our spring loaded stem seal provides automatic compensation for stem seal
wear and thermal expansion and contraction. Each valve is bubble tested to ensure
reliable, leak tight performance.
The BV80 Series are ideal for automation when coupled to our compact pneumatic
or electric actuators.
