Selectomite® 71 and 76 Series 3-way Ball Valves
 |
Selectomite® 3-way ball valves use 180° operation for diverting flow from one line to another. The handle points to the side port in use; when perpendicular to the side ports, it indicates the shutoff position. |
Typical Applications
- Instrument air lines
- Sampling systems
- 2-way gauge readout of line pressure
- Manual cylinder actuation
Features & Benefits
- Handle points to port in use or to closed position, providing a visual cue and improved safety.
- Dyna-Pak® packing provides a leak-tight seal with low operating torque in vacuum or high pressure applications, helping to prevent fugitive emissions.
- Dual encapsulated TFE seats and microfinished ball ensure a leak-tight seal. This combination provides greater valve reliability.
- TFE seats and washers provide excellent corrosion resistance, providing the correct material for the application.
- A wide variety of HOKE GYROLOK® end fittings or pipe fittings provide the correct fitting option for the application.
- Special High Tolerance NPT Thread
