The dual valve consists of a die-cast valve body containing two pneumatic reducing valves operated by a handle and a rocket arm.
The pressure reducing valve used in these assemblies is a three-way type and has low hysteresis.
Moving the lever out of centre position, results in an increasing pilot pressure, proportional to the lever position.
The pilot pressure controls the servo cylinder or the pool control in the hydraulic directional valve. Moving the lever back to the centre position will reduce the pressure and exhaust the air through the valve.
Advantages and Applications
Dual and Quad valves are single and dual axis, pneumatic servo control valves, used mainly for controlling hydraulic directional valve and pump actuators in mobile applications.
This type of valve is used for remote control in applications not requiring the very high precision offered by an electronic control system.
The system improves the operator comfort and also give the designer a freedom of choice when locating the hydraulic components. The system is in expensive and easy to install.
Typical applications are fork lift trucks, dump trucks, refuse vehicles and hook loaders.
Design and Function
The range of pneumatic servo valves includes a number of different options, such as:
Valve with single axis lever, for one double-acting function.
Valve with dual axis lever, for two double-acting functions.
Single axis valves, block-mounted, for up to eight double-acting functions.
Levers with electric switches.
Levers with pneumatic sequence valve.
Valves with mechanical detent in different positions.
