Use with caustic and high-purity liquids in many applications.

• All-PTFE valve is precision machined

PTFE stopcocks function in a manner similiar to ball valves but have a tighter seal when closed, making them ideal for applications where vacuum and pressure will be used. Valve is fully open when handle is in the direction of the flow, and fully closed when it is perpendicular to the valve. At a 45° position, the valve is half open, and can thereby be used in metering applications.
