1/2″ 2-Way, Stwy – 250 Psig Static
Application
VB-7211 series stem up open, two-way valves control water from 20 to 281°F (-7 to 138°C) or steam to 281°F (138°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.
Features
- Valve sizes 1/2” to 1-1/4”
- Equal percentage flow characteristics for two- position or proportional control of water or steam
- 250 psig pressure rating per ANSI Standards (B16.15–1985) for cast bronze bodies
- Spring-loaded TFE packing
- Union end American Standard Taper Pipe Thread (NPT) connections
- Straightway or angle body pattern
