PTFE Suckback Valve
This combination valve performs two simultaneous functions. Being a normally closed valve, it requires air to actuate. When switching from the open to closed position, its unique design creates a vacuum on the discharge port and immediately "sucks back" a predetermined amount of liquid. The adjustment knob on the top of the valve gives excellent repeatability on the suckback volume. This valve is the perfect solution for dispensing equipment to prevent dripping of solution from dispense nozzles.

ACR Valve
The media path of the valve is fabricated from Virgin Grade PTFE while the pneumatic side is fabricated from PVC or P.V.D.F. resulting in a large flow valve, capable of handling harsh chemicals internally while operating in extreme environments externally.

Air Cylinder
Air activated retractable cylinder with your choice of PVC, Polypropylene, or P.V.D.F. construction.

Air-op Dilution Drain Valve
Standard dilution rates-2:1 and 6:1. Other dilution rates available, but higher dilution rates will cause slower drain rate. Also available without the pneumatics.

Air-op Aspirator
The Air-Activated PTFE Aspirator is designed for easy siphoning of harsh chemicals while eliminating chemical dilution common to liquid aspirators.

Diverter Valve
Divert hazardous chemicals to separate drain, or divert DI water/chemicals to reclaim. Large orifices provide maximum flow. Available in PVC, Polypropylene or P.V.D.F.

Large Orifice Pneumatic Drain Valves
These versatile valves may be ordered in air-to-open/air-to-close or spring return models. Select from 2,3 or 4 way configurations where each port may be independently activated for maximum utilization. Valves may be ordered with P.V.D.F. body construction and Kalrez® O-rings.

DI Water Valve
Perfect valve for wet benches where DI water is required. Wetted path is free of lubricants, elastomers and springs.

Foot Valve
Manufactured from either PVC, Polypropylene, or P.V.D.F.
