HYDRAULIC VALVES
Armadillo’s hydraulic valves offer precise control over flow and pressure for improved system efficiency. These directional control valves fine-tune machinery movement, optimizing speed and response in equipment. By delivering smooth and accurate fluid control, our valves increase productivity and energy efficiency in agriculture, mining, construction, and manufacturing operations.
HYDRAULIC VALVES
Built for safety and reliability, Armadillo’s valves prevent leaks and unintended motion in critical systems. Each valve is engineered with fail-safe mechanisms to maintain control even under extreme conditions. This means heavy machinery and industrial equipment operate securely, protecting your crew and assets while minimizing downtime due to malfunctions.
HYDRAULIC VALVES
Our valves are designed in-house and customisable to meet specific project needs. Whether you require a compact flow control or a high-capacity relief valve, we tailor solutions that seamlessly fit your hydraulic system. This customisation ensures optimal performance, giving engineers and project managers the precise control they need.
HYDRAULIC VALVES
From mining excavators to factory automation lines, Armadillo’s hydraulic valves excel across diverse applications. They adapt easily to different machinery, whether controlling heavy-duty mining equipment or fine-tuning agricultural implements. Project managers across industries trust these versatile valves to deliver consistent, reliable performance wherever precise fluid control is required.
Quality hydraulic valves generally last 5–10 years or more with proper maintenance. Lifespan depends primarily on fluid cleanliness, pressure cycles, and operating conditions.
Minimal maintenance—mainly ensuring clean fluid, regularly checking for leaks, and verifying valve operation. Replace filters and fluid on schedule to prevent contamination.
Choose valves based on their type (directional, pressure control, flow control), pressure rating, flow capacity, fluid compatibility, mounting style, and actuation method (manual, electric, hydraulic pilot).
Contaminated fluid is the main cause of valve failure. Other reasons include worn seals, incorrect installation, or using a valve with inadequate pressure or flow ratings.
Ensure cleanliness during installation, use new O-rings lubricated with hydraulic fluid, tighten fittings to manufacturer specs, check valve orientation carefully, and test thoroughly after installation.
Hallite seals are hydraulic and pneumatic sealing products manufactured by Hallite Seals International, a well-known global brand in the sealing industry. They are used extensively in hydraulic cylinders, pumps, and other fluid-power applications to control leakage, exclude contaminants, and maintain system pressure. While many manufacturers claim they use Hallite they are mostly copies.
You should set the relief just above your true maximum working pressure—but below the rating of the weakest component. A common starting rule is to set 10–15% above the maximum pressure required to complete the job, then fine-tune under warm oil, full-flow conditions. And if possible, make sure your system has either a pressure gauge or a test point.
“OCV” in hydraulics usually means an Over-Centre Valve (sometimes also called a counterbalance valve). They are used mainly on hydraulic cylinders or motors that are subject to overrunning loads (where the load tries to run away faster than the pump is feeding oil).
How to set the cracking pressure
The OCV’s “spring setting” (or cracking pressure) is set relative to the load-induced pressure on the actuator.
Typical rule of thumb:
Set at 1.3 – 1.5 × the maximum load-induced pressure (sometimes up to 1.8× if more damping is needed).
