The pilot operated check valve for legs DN31 was developed by DAT Bergbautechnik in consideration of the special requirements for large legs with high flow rate.
The 2/2 way valve cartridge is designed for high flow rates and thus enables nominal diameters up to DN31SSO.
This valve also has an intern hydraulic decompression, which ensures its smooth opening and closing. DAT paid special attention to the transmission ratio of this valve.
The purpose of this is to ensure, that the valve can be unlocked with low pump pressure also at high loading of the legs.
