Break Pressure Tank

Break Pressure Tank

A break pressure tank is the most reliable method of breaking pressure in bulk and reticulation water supply networks. They are generally used in rural areas where little or no maintenance is carried out.

Reasons to consider using a break pressure tank rather than a pressure reducing valve include:

less maintenance
break pressure tanks, operating in the same system, won’t “hunt” against each other like pressure reducing valves do.
break pressure tanks have a higher turndown ratio than pressure reducing valves.
even if the break pressure tank fails, the downstream pipeline will never be exposed to excessive pressures.
a break pressure tank has fewer components than a conventional pressure-reducing installation.

Description

CONSTRUCTION

The break pressure tank consists of the following:

1000L 3cr12 stainless steel tank
basket strainer with flush valve
butterfly valve for isolation
diaphragm operated level control valve
inlet, outlet, and overflow pipework

OPERATION

The diaphragm valve in the BPT opens and closes as system demand fluctuates. The flow into the tank is automatically regulated to match the system demand thereby ensuring that the velocity in the upstream pipeline is limited to the design flow rate. Opening and closing occur gradually to prevent unwanted surges and water hammers.
