OPERATION
  
Valve is held closed permitting a
tight seal by both tank pressure
and the valve’s closing spring.
As the actuator moves the
operating lever to mid-stroke,
rapid equalization occurs
through the enlarged bleed ports.
Tank and downstream volume
pressures equalize quickly with
the Jet Bleed Internal™ Valve trim
and the main poppet opens.
FIELD PROVEN FEATURES
Fisher C Series Internal Valves have long been known
for reliability, the Fisher Jet Bleed Internal™ Valves
carry that tradition forward.

PERFORMANCE and VALUE
New Fisher
®
Jet Bleed Internal™ Valves target speed
of opening issues commonly encountered in the
operation of internal valves. Enlarged bleed ports
provide faster equalization of tank pressure and
downstream line pressure, giving a faster response
time for quick valve opening.
• Allows operators to be more efficient
• Reduces potential for damage caused by
running pumps dry
• Improved service features for
easy maintenance
