Check Valves
Wafer Check Valves Technical Data and Installation
MODEL:WAFER CHECK VALVES(CW1000.CW2000.CW3000,CW4000)
Wafer check valves is a general purpose and one way flow valves. Due
to lighter in weight and short dimension, wafer check valves is very easy
to be installed between flanges. Inner parts assembled by two semicircle
springs and plates, which pinned to the body. Normally closed by spring
action and open by fluid pressure. Because the spring cycle reaction is
very quick, it could protect the pipe from wafer hammer.
Precautions in piping
-
Lay pipes so that the cast direction of wafer check valves
body corresponds with the flow direction.
-
It can be installed in vertical piping. In horizontal piping, set the rib wafer check valves vertically.
-
Use an extension tube between wafer check valves and
butterfly valves, never connect the wafer check valves to the valves
directly.
-
Avoid entering the end of a tube or gasket within the
operating of a radius of the wafer check valves discs.
-
Never mount a reducer just in front of or behind the wafer
check valves
-
When installing a wafer check valves near an elbow, leave a
space as large as possible between them.
-
When installing a wafer check valves at a pump outlet, leave
a space at lease 6 times of valves diameter and be sure that the
plate is evenly stressed by fluid.
