Gate valves in industryThegate valve, also known as asluice
valve, is avalvethat opens by lifting a round or rectangular
gate/wedge out of the path of thefluid. The distinct feature of a
gate valve is the sealing surfaces between the gate and seats are
planar, so gate valves are often used when a straight-line flow of
fluid and minimum restriction is desired. The gate faces can form a
wedge shape or they can be parallel. Gate valves are primarily used
to permit or prevent the flow of liquids, but typical gate valves
shouldn't be used for regulating flow, unless they are specifically
designed for that purpose. Because of their ability to cut through
liquids, gate valves are often used in thepetroleumindustry.
The design of gate valves makes them ideal for the free flow of
fluid when minimum restriction is desired. When a gate valve is
wide open, the gate is completely drawn up into the valve body,
allowing for pressure and flow through the valve that is consistent
with the attached pipe.Rising or Non-Rising, Threaded or Flanged
Gate ValvesGate valves are classified as either rising or
non-rising stem valve. A non-rising stem valve has its stem
threaded on the lower end into the gate. Even though the gate
travels up and down, the stem remains vertically stationary;
whereas in a rising stem gate valve, the stem is attached to the
gate, and both the gate and stem rise or lower simultaneously. Gate
valves are available in a threaded or flanged gate valve
design.
industrial valves and systems are engineered to provide
continuous reliable performance under the most rigorous and
demanding operating conditions. Industrial valves are at work all
over the world delivering durable, reliable performance across the
full spectrum of industrial applications.
Industrial valves are used to control machine functions in the
harsh environments and under the demanding continuous duty cycles
of todays manufacturing and processing operations. Engineered for
reliable performance and long service life, these valves deliver
increased productivity and improved performance in the full range
of industrial applications. Industrial valves can be found anywhere
in the world machines are used to cut, groove, bore, clamp, inject,
press, form, lift, dig, haul or perform other functions
required.
Main benefits of using Gate valve :-I. Little friction and
minimal drop in pressure when fully openedII. Eliminates leaksIII.
Rising stem configurations make visual inspections easyIV. Non
rising stem configurations are ideal for areas underground or where
space is limited
