Series 50
Flangeless, Wafer Ball Valves
Rev: 01 | 01-2014 | Nº: VW50
Flangeless, Wafer Ball Valves
Compact, flangeless ball valves designed for installation between ANSI Class 150# and 300# flanges. Easy to automate &
control at maximum flow capacity with minimum torque & pressure loss.
VALBOL Series 50 wafer Ball Valves are designed to meet
all standards in a wide variety of industries including, chemical processing, petrochemical, oil and gas production, pulp
and paper and others. Capable of handling a wide range of
liquids and gases in these industries, these valves offer all
the advantages inherent in a ball valve; quick, quarter-turn
operation, visual indication of the valve position, light weight
compact size.
Available in sizes 3”, 4” and 6” these wafer valves are designed to mount between ANSI flanges class 150# and 300#.
with fire safety, their rugged construction facilitates inspection and repair while insuring long life and durability. Like all
Valbol ball valves, they offer tighter shutoff, high cycle life
with lower torques to operate, and the ability to automate
with a choice of pneumatic or electric actuation.

Automation
VALBOL offers a complete line of pneumatic and electric automation packages for Series 50 valves. Both pneumatic
and electric packages are offered for on/off or proportional
control. Available options include
• Top mounted limit switches
• Proximity switches
• Single and double acting pneumatic actuators
• TYPE 4, 4x, 7 and 9 enclosures
• Remote position indication
• Positioners
PTFE Seat
Before an actuator can be sized for any given valve application the operating torque required for the valve must be
determined. The operating torque of a ball valve is influenced by a number of factors, some are design and materials
related, others are application and service conditions. Design related factors include the type and material of the valve seats, while application factors include system differential
pressure, media and frequency of operation. For complete
valve operating torque data refer to the torque curves given
for each seat material, and provide the correction factor for
media and the type of service such as on-off operation, cycle frequency, etc.
