▪ For high, pulsating pressures
▪ For customer philosophy “Soft sealing / non metal to metal seal”
▪ Pneumatic applications
▪ Filling (flow in opposite direction) SKK-FÜLL
Area of Application
▪ Monitoring and control of pressure
▪ Venting
▪ Sampling in high- and low-pressure systems
▪ Filling of accumulators (special filling-version)
Advantages
▪ Coupling at system pressure level
▪ Leakproof connection before ball valve is open
▪ Simple connection to measuring, control
and switching devices
