COAX V2 Special Valves

The COAX V2 Special Valves are 2/2-way, externally controlled valves with an orifice size ranging from DN15 to DN100, capable of handling pressures from PN 0 to 64 bar. Designed with a spring return mechanism, these flanged valves are built with nickel-plated steel or stainless steel bodies, using FPM or graphite seals. Ideal for gaseous media, they excel in demanding applications such as hot gas filtration and filter cleaning within coal gasification processes in power stations.
