valve is equipment that is utilized in a household as well as in a
large industry; the types of valves obviously differ as per
requirement. The basic function of a valve is to either check or
control the flow of a fluid. There is also pressure-check valve which
has a different function altogether. One may wonder why different
types of valves are designed for such an incomplex task. It is
because different types of flows like partial flow, full flow or no
flow are required by industries. Valve types like the gate valve are
suitable only where full or no flow is needed, for throttle purposes
a gate valve is of no use. Gate valves are best suited for industrial
usage where high flow, for a prolonged time is required.
gate valve is generally classified according to its parts. Valve trim
is the main part of any gate valve. Stem, discs and seat are the
sub-parts of a valve trim. Rising stem and non-rising stem are the
two types of discs used in a gate valve. Expanding gate valve is
available in both types. The mechanism of both rising stem and
non-rising stem is easy to understand. In case of a rising stem, the
stem (shaft) rises above the handwheel of the gate, when the valve is
opened. In case of a non-rising stem design, the stem does not move
upward, only the disk moves upward while the stem remains still.
Sometimes, two padlocks are needed to lock the expanding gate valve.
The advantage of rising stem over non-rising stem is that it is
possible to tell the open or close position of the valve with a
rising stem. Non-rising stem valve is suited for equipment which do
not have enough space for the stem (shaft) to rise. Also, only one
padlock is needed to lock a non-rising stem gate valve.
gate valves manufactured by Integrated Equipment have close machining
tolerance which provides a valve that can seal under almost all
conditions. Some of the other features provided by our design of
expanded gate valves include F-1 seats, valves that provide positive
sealing and conform to API 6A. Our expanding gate valves are
forged/cast in alloy or stainless steel. We also provide bolted
bonnet for easy change out of internal parts.
with Expanding gate valve, we, Integrated Equipment also
manufacture FC style gate valve. Other wellhead equipment like tubing
head and spools, studded tees and crosses, tubing head adapter, X-mas
tree components and so on are also manufactured at Integrated
Equipment. We can also build custom products for our clients, after
all client satisfaction and quality products are our two principle
