Why happy stock are healthier stock
Editorial written by Philmac for the Summer 2020/2021 Seasons Magazine
In Australia, there is growing interest in maintaining the quality and availability of stock water.
A simple, yet effective, idea is to fit shade over water troughs. It provides stock with some relief from the sun and should also lower the water temperature, which in turn may reduce the amount of algal growth and water loss due to evaporation.
Ideally, float valves should be matched to meet the water demand of the stock. Rather than considering the maximum flow of the valve, selection should be based on the pressure the float valve operates at the trough. Quite often this may only be around 100 kPa (15 psi).
Dealing with a variety of water pressure on the one property is a common problem. Farmers are faced with having a range of different float valves on hand to enable them to deal with the high and low water pressures they encounter.
The Philmac 200 Series High Flow Float Valve solves this problem as it comes with a high-pressure adaptor. This float valve delivers very high flow at both high and low pressure, meaning you only need to carry the on-float valve with you and, no matter what the pressure is at the trough, you’ll have it covered.
Many farmers are now installing additional troughs to ensure stock do not have to walk as far for water, but also to optimise feed utilisation within a paddock.
More troughs means more float valves. But as long as a regular maintenance program is followed, most valves will provide years of trouble-free service. A properly operating valve means no loss of precious water.
“In dry seasons, you don’t want things going wrong with fittings and valves, so we use Philmac products because they’re reliable, cost-effective and easy to use,” said Brendon Finger, “Telarah”, Clermont, Queensland.
Your trough valve maintenance program should start with checking that the lever arm moves freely up and down. If there’s any “stickiness” it could be due to debris, a bent pivot pin or, in the case of a sleeve valve, a dry O-ring.
If the valve weeps, it is likely the seal is worn or clogged with debris.
Once the valve is disassembled, it’s easy to check for wear in the seal, and that the valve is clean.
Fitting a new seal to a Philmac 200 Series float valve is as easy. Simply prise it from the flapper. In most cases, you can turn the seal over and reuse it.
When replacing a Philmac 120 Series float valve seal, it is recommended that the O-ring on the plunger be re-greased with rubber grease. More detailed information on installing Philmac float valves and their maintenance is available in the installation section on the Philmac website.
At Philmac, we recommend regular maintenance of float valves and provide a full range of spares to ensure years of trouble-free operation.
