Overview
DW type distributing valve is used for dual line system. The ports are doubled in number from single discharging type (1 port/element) to dual discharging type (2 ports/element) for saving space.
Features
• Double the Number of Discharging Ports
Only half the conventional number of distributing valves is needed for the required number of lubricating ports. This simplifies installation and the piping configuration.
• Odd Number of Ports Easily Supported
Dual discharging can be easily changed to single discharging by simply reassembling the cross-port hexagon socket head flat plug on the right end to the discharging port. (See below for details on change method.)
• Maximum Operating Pressure of 21 MPa
Application of higher pressure improves lubrication reliability and enables lubrication over a wider area.
• Same Installation Dimensions
The installation dimensions of DW-30, 40 and 50 types are all the same. This means that connections between distributing valves and resizing can be easily performed.
• Solid, Outstanding Durability
