Available in 1/2” through 2”, the SST ball valve features a precision-machined PVC ball with center provisions to support PTFE seats from zero to 100 percent of capable flow. The Type-21a SST ball valve produces equal percentage flow characteristics for fine throttling. The valve requires directional installation and comes equipped with a flow direction label.
Manually operated SST ball valves include a zero-to-100-degrees indicator plate and an indicator line on the handle, which doubles as a carrier adjustment tool. An ISO 5211 top flange bolt pattern and integrally molded base pad for panel mounting are standard on all Type-21a SST ball valves, and the valve body is PVC with either EPDM or FKM O-rings.
Socket, threaded and flanged end connections are all offered for the SST ball valve, and additional options include electric or pneumatic actuation with 4-20mA control, stem extension, and 2” square operating nut.
