Plug and adapter versions Special design for highly viscous media or applications with low operating pressure The standard version of the PA valve with a tapered plug has a travel of 3 mm, producing an angular gap of 0.5 mm over a length of 20 mm. With a travel of 3 mm the special flat plug produces a full cross section of the outlet opening of 10 mm. • higher viscous media and The suitable valve plug is selected according to the viscosity/operating pressure diagram (see page 4). • media with a low operating pressure Richter should be consulted in case of different application parameters....
