Water doesn’t always behave the way you expect it to, especially in a long irrigation line. One end might gush, the other trickles. Pressure drops, flow fluctuates, and suddenly your “uniform irrigation” isn’t so uniform anymore.
Hydraulic flow control valves in such situations can come in handy as they are designed to manage these pressure shifts while keeping your irrigation system balanced, whether you’re using sprinklers, drips, or filters.
Automat builds these control valves for irrigation to take the stress out of irrigation, especially in fields where pressure isn’t always predictable. Although it is a small component, the valve plays a big role in keeping your system efficient and your crop consistently watered.
How Do Hydraulic Flow Control Valves Manage Pressure?
A hydraulic flow control valve matters for balancing irrigation pressure across your system. As an alternative to relying on manual adjustments, the hydraulic valve uses the pipeline’s own pressure to regulate flow automatically, ensuring stable performance even when the input pressure fluctuates.
Automat’s hydraulic control valves are engineered with responsive diaphragms, durable construction, and internal designs that minimise head loss. Be it a filter backwash setup or an open-field irrigation system, these valves ensure your lines run smoothly, efficiently, and without pressure shocks.
Filter Backwash Hydraulic Valves
If your filters keep clogging or cleaning them means shutting everything down, you know how frustrating that gets. The Filter Backwash Hydraulic Valve takes that trouble off your hands and automatically cleans out sand, disc, or screen filters. Designed with a double-chamber, it reacts quickly and works smoothly even when the pressure dips. It runs at just 0.8 bar, which means it doesn’t need much to do its job. Also, it is light, corrosion-resistant, and easy to install outdoors.
Built from UV-stabilised plastic and fitted with a stainless steel shaft and strong internal seals, it is a solid addition to your system. The internal parts are designed to reduce wear and tear from friction, while the short valve travel helps it respond faster and more accurately. Whether you’re dealing with a single filter or a full battery, this valve keeps things clean and flowing without constant maintenance. Just hook it into your 3-inch line (threaded or grooved) and let it do its own thing.
Bronze Hydraulic Control Valve
When you want a smooth shutoff without fuss and a valve that doesn’t give up under pressure, this one fits right in. Automat’s Bronze Hydraulic Control Valve is built simple with just four main parts, but it does some heavy lifting. The bronze body can take on daily field wear without rusting or warping, and the metal-reinforced rubber lid holds its seal tight even when pressure spikes.
Its internal design keeps head loss low, so your pump doesn’t have to overwork to maintain flow. Compatible with most irrigation controllers in the market, this valve is often used in turf irrigation, greenhouse setups, or open fields where steady water control matters. It handles flows up to 97 lpm (depending on size) and operates across a wide pressure range. Once installed, it stays dependable through the seasons.
Where Do They Work Best?
Not every field needs the same kind of pressure regulation. If you are dealing with variable pressure or need to automate part of your irrigation, a hydraulic flow control valve can make a lot of difference. They’re especially useful in:
- Filter stations where automatic backwashing is critical
- Greenhouses and nurseries that need precise pressure control
- Large open fields where elevation and pipe length create a pressure imbalance
- Turf systems where even watering keeps the landscape healthy
They can also be paired with pressure-sustaining or pressure-reducing pilots for even more control, helping you fine-tune flow across different field zones.
Valves Matter More Than You Think!
Too often, valves are treated like background parts — installed and forgotten. A faulty or missing control valve can lead to irregular watering, wasted water, or even pipe damage over time. That loud clunk you sometimes hear when a pump shuts off is called a water hammer, and it can crack pipes or wear out joints. A good hydraulic valve prevents that. Adding the right valve isn’t just a technical decision; it’s peace of mind.
So if you’re building a system meant to last, don’t overlook the humble hydraulic valve. Whether it’s a butterfly valve type or another essential component, It keeps your irrigation steady, your components safe, and your crops watered just right. Sometimes, the parts you don’t see working are the ones doing the heaviest lifting.
