Description
Dual Plug Valves, also known as cock or stop-cock
valves are typically used in both on/off and throttling
services.
The simple design consists of three parts: the body,
cover and plug. The plug is a cylindrical device that can
be raised or lowered within the seat to maintain, restrict,
or completely shut off flow.

Operation
S&K Dual Plug Valves are mounted between two oil
coolers inside the reservoir tank. The valve is piped to
the system inlet and outlet and to inlet and outlet ports on
both coolers. During operation only one cooler is in
operation and the other cooler is isolated. The valve is
rotated to select operation on the desired cooler.

Applications
Dual Plug Valves are extremely versatile valves that are
used in low-pressure sanitary and industrial applications,
especially petroleum pipelines, chemical processing, and
power plants, among others. They are high capacity
valves that can be used for directional flow control even
in moderate vacuum systems. Dual Plug Valves can
safely and efficiently handle gas and liquid fuel, and
extreme temperature flow such as boiler feed water,
condensate as well as to regulate flow of liquids slurries.
