Application
VB-7285 series single seat, stem up closed, two-way valves control water from -7 to 205°C or steam to 205°C maximum in heating or air conditioning systems. They are used for two-position or proportional control applications. Valve assemblies require an actuator and a valve linkage that must be purchased separately.
