Stopcock Valves
PTFE Stopcocks (Plug Valves)
- Precision Machined PTFE
- Available in 2, 3, and 4 way body styles
- Available in both FNPT and Tubing Connection sizes from 1/8" to 1/2"
Specifications
- Media Pressure: Vacuum to 60 psi
- Media Temperature: 100º
- Ambient Temperature: 50º
- Sealing: Bubble Tight
- Shutoff: Positive
- All Wetted Surfaces: PTFE
The following PFA Stopcocks are also available...
1/8" Orifice, 2-Way
- All wetted parts are PFA and PTFE
- Small compact design provides minimal internal volume
- Several connection sizes available
Specifications
- Pressure Range: 27" Hg vacuum (913 mbar) to 50 PSIG (345 kPa) up to 150°F (65°C).
For every 2°F (1°C) temperature rise above 150°F (65°C), subtract 1 PSIG (6,9 kPa)
from 50 PSIG (345 kPa) to calculate the maximum pressure rating.
- Temperature Range: 0° to 200°F (-17° to 93°C), ambient; 0° to 250°F (-17° to
121°C), fluid
- Materials: PTFE stem, PFA valve body
1/8" Orifice, 2-Way, 90°
- All wetted parts are PFA and PTFE
- Small compact design provides minimal internal volume
- Requires minimal space for mounting. Ideal for draining filter housings.
