Ideal flow rates
March 2003
Pneumatics & Hydraulics
The LS04 pneumatic valve series from Rexroth sets itself apart with small dimensions of only 10 millimetres width and flow rates from 200 l/min up to a maximum of 330 l/min. This makes the series well suited to the requirements for most assembly applications, as well as for numerous handling tasks. With the LS04, Rexroth has rounded out its range of pneumatic valves with high levels of functionality and reliability.
The valves are available in three different designs:
* A mini valve with optimised dimensions and a flow rate of 200 l/min.
* A standard valve with 250 l/min.
* A valve terminal system with a flow rate of 330 l/min.
All valve variants are made of high strength polymer and are especially light. The sealing system is the same as that already used in the proven HF04 series.
The LS04 features integrated push-in fittings for imperial or metric tubing. The electrical connections for the types vary:
* The inline single valves are equipped with an M8 or standard connector.
* The valve terminal system has a multi-pin connection that can be used to control up to 24 coils.
Users can implement mixed configurations with single and double solenoid or double 3/2-way valves. Additionally, users can create different pressure zones or supply circuits in the valve terminal system using separators that can be positioned anywhere, making it possible to adapt the configuration to individual demands. Another advantage is that the plug-in style valves can be exchanged easily and quickly, without interfering with the electrical connections. The system can also be expanded to incorporate two more valve positions.
Despite the small dimensions, the maintenance-free, compact mini valve option covers a variety of needs in modern valve technology for flows of up to 200 l/min. As a 5/2-way valve, it takes care of the most common valve functions and can be operated with lubricated or non-lubricated compressed air supply. This also applies to the standard valve, particularly with the double 3/2 function. Users in handling technology can also directly mount the LS04 on moving parts, thanks to its light weight. Even vacuum applications can be implemented with this valve, as it uses an external pilot air supply.
