Germany
Valvesonly
Europe is one of the best Gate Valve
Manufacturers in Germany. Gate valves play a crucial role in controlling the flow of fluids in
various applications. These valves are known for their robust construction and
reliable performance.
What is a Gate Valve?
A gate
valve is a type of valve used to regulate the flow of fluid through a pipeline.
It operates by raising or lowering a gate or wedge-shaped obstruction to either
allow or block the flow of fluid. Gate valves are commonly used in systems
where straight-line flow and minimal pressure drop are desired.
Working of Gate Valve:
The working
principle of a gate valve is relatively simple yet effective. When the valve is
open, the gate is lifted to allow the fluid to pass through freely. Conversely,
when the valve is closed, the gate is lowered to obstruct the flow completely.
This on-off functionality makes gate valves ideal for applications where tight
shut-off is essential.
Function of the Stem on a Gate Valve:
The stem on
a gate valve serves a crucial function in its operation. It is responsible for
raising and lowering the gate to control the flow of fluid. When the handwheel
or actuator attached to the stem is turned, it transfers the motion to the
stem, causing the gate to move accordingly. Thus, the stem acts as a mechanical
linkage between the operator and the gate, enabling precise control over the
flow.
Gate valve types:
·
Rising Stem Gate Valve
·
Non Rising Stem Gate Valve
·
Bellow Seal Gate Valve
·
Pressure Seal Gate Valve

Gate Valve Diagram and Parts:
A typical
gate valve consists of several essential components:
·
Body: The main outer casing of the valve.
·
Bonnet: Encloses the valve internals and provides a connection point
for the stem.
·
Gate: The obstruction that either allows or blocks the flow of fluid.
·
Stem: Transfers motion from the operator to the gate.
·
Seat: Provides a sealing surface for the gate to achieve a tight
shut-off.
·
Wedge: The portion of the gate that meets the seat.
·
Handwheel or Actuator: Used to operate the valve manually or
automatically.
·
Stem Nut: Secures the stem and provides a means for transferring
rotational motion.
Gate Valve Operation:
The
operation of a gate valve involves the following steps:
·
Open Position: The handwheel or actuator is turned counterclockwise,
lifting the gate to allow fluid flow.
·
Closed Position: The handwheel or actuator is turned clockwise,
lowering the gate to block the flow of fluid completely.
·
Intermediate Positions: Gate valves can also be partially opened or
closed to regulate the flow as needed.

Double Offset Butterfly Valve
Manufacturers
Valvesonly Europe is your premier Double
Offset Butterfly Valve manufacturers Germany and Italy. Double offset
butterfly valve is a type of butterfly
valve used in high perfromance applications. The double offset design of a
double offset butterfly valve allows the disc to move away from the seat via
action mechanism, hence the name. A double offset butterfly valve is a type of
quarter-turn valve used to control the flow of fluids in pipelines. It earns
its name from its unique design, featuring two offsets:
l The
first offset involves the shaft positioned behind the valve disc.
l The
second offset slightly shifts the shaft position behind the valve disc in
relation to the pipe centerline.
This dual offset configuration enables the valve disc to
move in a cam-like motion when opening or closing, minimizing friction between
the disc and the seat. As a result, the valve provides a tight seal with
reduced wear and tear, allowing it to operate effectively even in high-pressure
or high-temperature applications.
Difference between Double Offset and Triple Offset
Butterfly valve?
The primary differences between double offset and triple
offset butterfly valves lie in their design complexity and sealing mechanisms:
1. Number
of Offsets: Double offset butterfly valves have two offsetswhile .
2. Triple
offset butterfly valves have three offsets: the first two offsets are similar
to those in double offset valves, while the third offset involves an
asymmetrical shape in the sealing mechanism
3. In
double offset butterfly valves, the sealing mechanism is primarily achieved
through a combination of the offset design and the interference fit between the
disc and the seat. Whereas in Triple offset butterfly valves utilize a
laminated or metal-to-metal sealing mechanism in addition to the offset design.
4. Double
offset butterfly valves are suitable for a wide range of applications where
reliable sealing and moderate operating conditions are required. Triple offset
butterfly valves are typically used in demanding applications where tight
shut-off, high-pressure, high-temperature, or corrosive conditions are present,
such as in oil and gas, petrochemical, and refining industries.

Electric
Actuated Gate Valve manufacturer in Italy
Valvesonly Europe is one of the trusted
electric actuated gate valve manufacturer in Italy. Electric actuated gate valves is a type of
valve which is controlled by an electric
actuator to open or close the gate, allowing or blocking fluid flow in the
industry process.
What does an electric actuated means?
“Electric actuated" means a device that
is powered by electricity to perform an
function. In this context of gate valves, being "electric
actuated" means that the valve is operated or controlled using an
electrically powered actuator. This actuator receives electrical signals or
power to move the valve's component thereby allowing valve to function.
How does it work?
The valve operated with the
help of the actuator, which moves a gate
inside the valve to regulate fluid flow. The actuator raises or lowers the gate
by turning internal gears in response to an electrical signal. When the gate is
lowered, the valve is closed and no fluid may pass through. When the gate is
raised, the valve is opened and fluid can pass through. These valves are
frequently accompanied by sensors that offer input on the position of the
valve, guaranteeing precise functioning and flow control.
