​​Pneumatic valves are constant-v​​olume type for critical mass balance applications

Teledyne ISCO dual pump air valve systems work reliably with almost any fluid, including viscous and/or corrosive solutions. The pneumatic, constant-volume valves experience no fluid loss or transfer when they open and close. They are automatically switched by the SyriXus controller, but require​​ an 80 to 100 psi air source.

Valves are made of Hastelloy C-276 with Chem-Raz seals, can be heated to 160 °C, and can be pressurized at any port.​​​​

​​​Reliable Hast​​elloy valves require no external compressed air or power supply

The electric valve package is driven entirely by the SyriXus pump controller and requires no other connections. The reliable stem-and-ball type valve has logged thousands of hours under harsh conditions.

Made of Hastelloy C-276 and Inconel 718, these valves can be heated to 200 °C and can handle a wide range of corrosive fluids, liquefied gasses, volatile fluids, and viscous solutions.​​
