OSQ flow amplifiers
OSQ flow amplifiers have an integrated steering priority valve and can be used with our OSPBX, OSPCX, or OSPLX steering units. They are ideal for vehicles with steering flows up to 400 l/min [106 US gal/min].
Features and benefits
- Enables operator to control high steering forces with relative comfort and safety
- Produces a system capable of steering vehicles weighing up to several hundred tons
- Can be supplied with built-in valves: priority, pilot pressure relief, shock, suction and/or back-pressure valve in the tank line
- Available with different amplification factors: 4, 5, 8, or 10
- High performance and embedded safety
- Optimized system efficiency and operator comfort
- Reduced installation cost due to less pipe work when used with flanged priority valve
Applications
- Tractors
- Combine harvesters
- Wheel loaders
- Excavators
