Steam Ball Valves / Condensate Ball Valves
The Vexve steam ball valve (type NAVAL) has specially been constructed for the use of steam, to meet the requirements of pressure and temperature.
Steam ball valves reduce the pressure of the incoming steam and thus regulate the steam temperature.
Vexve steam ball valves can be used in a variety of process control applications, such as heating and cooling systems
and are particularly suitable for hot air, hot water and steam in both open and closed systems.
