Inline hydraulic valves are the traffic controllers of a fluid power system. Unlike manifold-mounted valves, inline valves are designed to connect directly into a hydraulic line or pipe, allowing precise control of flow, pressure, and safety in hydraulic circuits. At Gerrard Hydraulics, we supply a full range of inline valves, including in-line hydraulic flow control valves, in-line hydraulic check valves, in-line ball valves, and in-line hydraulic pressure reducing valves, designed for durability and reliability in Western Australia’s toughest industrial and mobile applications.
Ball Valves – On/Off Control for Safe Isolation
Overview: Hydraulic ball valves are simple on/off devices that use a spherical ball with a through-hole. A 90-degree turn of the handle either allows full flow or completely blocks it.
Applications: Ball valves are ideal for system isolation, emergency shut-off, and maintenance drains. They are not suitable for precise flow control, but their reliability makes them indispensable in critical shut-off points.
Industries & Equipment:
- Oil & Gas: Isolating pump lines for maintenance.
- Industrial Manufacturing: High-pressure wash systems and fluid storage.
- Mobile Hydraulics: Fuel tankers and service vehicles for quick isolation.
Check Valves – One-Way Flow for Protection
Overview: Check valves act like one-way streets in a hydraulic system. They allow fluid to flow in one direction and prevent reverse flow automatically.
Applications: Protect pumps from backpressure, maintain system prime, and bypass filters or coolers when clogged.
Industries & Equipment:
- Agriculture: Hydrostatic drives in skid steers and Z-turn mowers.
- Construction: Log splitters to prevent kickback.
- Renewable Energy: Wind turbine pitch control systems.
Lock Valves – Pilot-Operated Check for Load Holding
Overview: Lock valves, or pilot-operated check valves, prevent cylinders from drifting due to gravity or internal leaks. They can be “unlocked” via a pilot signal when needed.
Applications: Essential for load holding in lifting applications where safety is critical.
Industries & Equipment:
- Material Handling: Forklifts and telehandlers for stabilizer legs.
- Construction: Crane lift cylinders.
- Transport: Car haulers’ ramps and dump trucks.
Needle Valves – Precision Flow Control
Overview: Needle valves feature a tapered point that restricts fluid flow gradually. They are designed for low-flow, high-precision applications where fine adjustments are critical.
Applications: Control cylinder or motor speed with high accuracy in sensitive systems.
Industries & Equipment:
- Aerospace & Laboratory Equipment: Precision testing and control benches.
- Construction: Excavator attachments such as rotating grapples and thumbs.
- Paper Mills: Roller tensioning systems.
Pressure Compensated Flow Control – Consistent Performance
Overview: Pressure compensated flow control valves are designed to maintain a steady flow rate regardless of changes in load or system pressure. This ensures hydraulic equipment operates consistently and efficiently under varying conditions.
Applications: These valves are ideal for maintaining uniform speeds in conveyors, agricultural sprayers, and rotating machinery, even when loads fluctuate or conditions change.
Industries and Equipment:
- Mining: Conveyor belts, drilling rigs, and material handling systems.
- Agriculture: Seeders, spreaders, sprayers, and other precision farming machinery.
- Automation: Factory production lines and hydraulic systems that require reliable, constant flow for smooth operation.
Shuttle Valves – Signal Selection for Safety
Overview: Shuttle valves have two inlets and one outlet, passing the higher-pressure signal to the outlet. They are ideal for “OR” logic operations in hydraulic circuits.
Applications: Enable emergency systems, dual control stations, or automatic pressure selection between two sources.
Industries & Equipment:
- Heavy Construction: Backhoes and excavators for dual-control circuits.
- Marine & Transport: Winches and emergency steering systems.
- Military & Mining Vehicles: Safety and pressure selection in critical operations.
