3 Instances In Which An Excess Flow Aussie Check Valve Could Save The Day

There are several reasons why excess flow check valves, such as those supplied by Equipco in Australia, are used. In several instances, they are, more than anything else, utilised as a precaution. Especially in some industries that feature fuel lines or other varying chemicals, they mustn't leak into areas in which they don’t belong. Excess flow check valves in the most appropriate areas have saved hazardous major spills on more than a single occasion. When used properly, they are capable of preventing safety hazards, releases, and helping to safeguard the environment as well as saving companies’ significant sums of money.


1. Rupture

When any transfer or loading line features a rupture, it can be quite disastrous. Particularly with high-vapour, flammable materials, a hose or line rupture could mean that dangerous liquids will get to escape. Excess flow check valves could save the day as the devices will notice the alteration of pressure and completely cut the flow of the gas or any other fluid so it no longer flows through the pipe at the particular point that has been ruptured. The flow doesn’t resume until the pressure has been equalised, which isn’t possible until the hose or pipe is fixed.


2. Disconnection

Unfortunately, workers do not always fully pay attention to the whole system. They could even have something disconnected without realising that there is fluid flow that is passing through it from one area to the other. This is among the foremost reasons why most industries use valves offered by Equipco Valves in Australia. If there has been anydisconnection in a flow line, the flow check valves that have been installed on such a line will sense the change in pressure and the disc of the valve will then close, thus preventing any further passage of the affected fluid.


3. Line break

Surely, line breaks do occur. Unluckily, the break might not be instantly sensed or noticed. Consequently, products could be spilled, thus bringing about a potentially explosive condition, great hazards to personnel safety, contamination problems and so much more. Flow shutoff devices will function to prevent any major release from happening. The line break that occurs will bring about a change in pressure and thus the valve will automatically close, thus preventing any flow wherever there is a break in the flow line of any fluid.


What can actually happen? Why on earth do fluid releases occur? We check and even go on to double-check, create checklists and have safety reviews. Yet chemical releases still do happen and their causes either when loading or when unloading are many. Hose fittings could pop loose, worn hoses could rupture, a car or truck could be inadvertently moved, operators could just disconnect the line by mistake, hose connectors do fail, traffic could puncture a hose, pipe fittings could burst, and pipes could rupture from accumulated corrosion and wear.


Whatever might have occurred, it all falls within the three categories listed in this article. And, they are the foremost instances in which excess flow check valves, such as those supplied by Equipco Australia, could be the devices that will save the day. These valves are valuable. Read more:
