NEWAY series BS ball valves are trunnion mounted
supported and available in size 2 to 48 , ANSI class
rating 150 to 1500 and temperature ratings of - 46 0C to
Series BS Trunnion Mounted Ball Valve
200 0C . All meets the fire safe requirement of BS 6755
and API 6FA.
Fully forged steel body and closure eliminates the
inevitable defects of casting and assures the tough
structure of the valve at full rated working pressure. It
also has advantage of quick delivery time, thus more
popular in modern oil and gas industry.
All BS series ball valves are featured with trunnion
mounted ball and independent floating spring loaded
seats which provides bubble-tight shut off and low
operating torques even at low different pressure. Double

expanding gate valve can be used up to 500 0C.
Neway through conduit gate valve size range from 2
~48 class rating from 150lb~2500lb, all available in
bolted bonnet or pressure seal bonnet.
Whether proof stem yoke
ISO 5210 mounting flange easily
for installation of gear, motor or
pneumatic actuator
Emergency Sealant Injection Fitting
prevent leakage from the stem
Vent valve to release the body cavity
Slab gate with Electric Nickel Plate
or Stellite No. 6 welding deposit
fitting prevent leakage from
the seat
Drain plug to release the residue within body cavity
Floating spring loaded seats with
double O-ring ensure efficient
total sealing even at low pressure
This is a typical NEWAY series GT Through Conduit Gate Valve illustrated cross-section drawing which is only for demonstrating of basic
design features. The actual product design may be slightly different from this sample drawing due to its size and pressure class.
