CAST STEEL VALVES
-
GATE VALVE
Gate valve is characterized by a sliding wedge which is moved
by actuator perpendicular to the flow direction. There are a
variety of valve sizes and types. The valve is used primarily as a
stop valve to open or close fully. Normally it works for slurries,
viscous fluid, etc.,but not for throttling. The gate valve usually
has a minimum pressure drop in full open and a tight seal in full
close, and therefore there is little possibility that contaminants
may enter the valve.

GLOBE VALVE
The globe valve is used where throttling alone or both throttling and shutoff is needed. It may also be used for
on-off service, but because of high pressure drop, such application is limited to the cases that the valve is
normally closed and the pressure drop is of no importance in valve open condition.
PK cast steel globe valve is regularly made in outside screw and yoke design with full-way type disc.
Sizes: 2” – 12”
Larger sizes are available upon request
ANSI Class: 150 – 1500

End Connections: Raised Face
Also available in RTJ and Butt Weld
Options: Y-Pattern and Stop Check
*Additional sizes and materials available upon request. Availability is dependent on market demands -
SWING CHECK VALVE
The swing check valve is designed so that it is opened
automatically at the forward flow and closed at the reverse
flow in horizontal or vertical (upward flow only through valve)
piping runs. It has an advantage of low pressure drop and
therefore is best suitable for velocity application.
