Bladder Gate Valve and Bladder Hose
Principle of the Bladder Gate Valve and Bladder Hose
The bladder gate valve provides water ow control in maintaining the bladder and lling the
furnace with water. The bladder hose provides a means for the water to freely ow from the
water jacket to the bladder allowing expansion and contraction.
Maintenance / Result
To maintain the bladder gate valve, open and close the valve periodically to prevent it from
seizing. Ensure that the hose clamp is tightly fastened, securing the bladder hose to the
bladder and to the bladder gate valve.
Removal and Replacement
1. Turn off the power to the furnace.
2. Drain some of the water from the furnace to prevent water from draining while you
are replacing the valve.
3. Loosen the hose clamp holding the bladder hose to the bladder gate valve.
4. Remove the bladder hose from the bladder gate valve and let the water drain from
the bladder.
5. Remove the old bladder gate valve and install the new bladder gate valve.
6. Attach the bladder hose to the bladder gate valve and tighten the hose clamp.
