Butterfly Valve Supplier
Valvesonly
europe is the largest Butterfly Valve Supplierin Germany. A butterfly valve is a
type of quarter-turn valve used to regulate the flow of fluids. Its name is
derived from the disc's movement, which resembles a butterfly's wings. This
disc, or vane, rotates around a central axis within the valve body to open or close
the valve, thus controlling the flow of liquid or gas through the pipe.
Butterfly valves are known for their compact design, efficiency, and ability to
provide a quick shut-off.
Where are
Butterfly Valves Used?
Butterfly
valves are versatile and used across various industries due to their efficient
operation and cost-effectiveness. Common applications include:
· Water and Wastewater Treatment: Used
to regulate water flow, control chemical additives, and manage waste discharge.
· Oil and Gas Industry: Essential for
managing the flow of crude oil, natural gas, and refined products.
· Chemical and Pharmaceutical
Industries: Handles corrosive and non-corrosive chemicals safely.
· Fire Protection Systems: Utilized in
firefighting water lines due to their reliability and quick operation.
Main Design
of Butterfly Valves:
Butterfly
valves come in several designs, each suited to specific applications. The main
types include:
· Wafer Type: This is the most common
type, designed to maintain a seal against bi-directional pressure differential
to prevent backflow in systems designed for unidirectional flow.
· Lug Type: This design features
threaded inserts (lugs) on both sides of the valve body, which allow it to be
installed using two sets of bolts and without nuts, providing a more secure
fit.
· Flanged Type: These valves have
flanges on either side that match the pipe flanges, making them easy to install
and remove.
· Double Eccentric (High-Performance)
Butterfly Valves: These valves have an offset stem that reduces seat wear and
allows for a tighter seal.
· Triple Eccentric (Triple Offset)
Butterfly Valves: These are used for high-pressure applications and provide
bubble-tight shut-off.
Working
Theory of Butterfly Valve
The working principle
of a butterfly valve is relatively simple. It involves a circular disc that is
fixed to a rod. When the valve is closed, the disc blocks the passageway
entirely. When the valve is fully open, the disc rotates a quarter turn to
allow fluid to pass through with minimal obstruction.
· Closed Position: The disc is
perpendicular to the flow direction, effectively blocking the flow.
· Open Position: The disc is parallel
to the flow direction, allowing maximum flow.
· Throttling Position: The disc is at
an angle between fully open and fully closed, which allows for flow regulation.
