We are India's one of leading manufacturers, suppliers
and exporters of Duplex stainless steel Check valves. We are known
as most prominent source of DSS check valves in India. Duplex stainless
steel Check valves are "automatic" valves that open with
forward flow and close with reverse flow. In this type of valves,
the pressure of the fluid passing through a system opens the valve,
while any reversal of flow itself will close the valve. Exact operation
will vary depending on the type of Check valve mechanism. Most common
types of Duplex Steel Check valves are swing, lift (piston and ball),
butterfly, stop and tilting-disk valves.
Duplex Stainless Steel Check valves are two-port
but one way valves, meaning they have two openings in the body, one
for fluid to enter and the other for fluid to leave. We manufacture
and supply various types of duplex steel check valves used in a wide
variety of applications across industries. Although DSS check valves
are available in a wide range of sizes and types, check valves generally
are very small, simple, and/or comparitively inexpensive. Check valves
work automatically and most are not needed to be controlled by a human
or any external control; accordingly, most do not have any valve handle
DSS Check valves are used in many fluid systems
such as those in chemical and power plants, and in many other industrial
processes applications. Duplex steel Check valves are also often used
when multiple gases or chemicals or fluids are mixed into one gas
or chemical or fluid stream. In this kind of applications check valve
is installed on each of the individual gas streams to prevent mixing
of these gases.
Check valves may have flanged ends which are drilled according to
pipeline compatible flange dimensional standards. Also can be Butt
weld and Socket Weld connection.
