Integral bleed valve
The integral bleed valve normally operates as a simple, directly controlled
bleed valve. As soon as the pressure exceeds the pressure value, which is
set using the large spring (1), it lifts the ball (2). The feed chemical then
flows out through the hose connection (5), e.g. into a storage tank.
