| No. | Name | Description | Reference picture |
|---|---|---|---|
| 11 | Two-Step Pneumatic Diaphragm Valves DPT Series | Quickly switches between low and high flow, cobalt alloy diaphragm provides high strength and corrosion resistance, ensures long cycle life, minimal particle generation and dead zones, is internally threadless and springless |
|
| 12 | High Purity and Ultra High Purity Bellows-sealed Valves | Precision-constructed bellows ensures reliability, non-rotating stem head increases switching cycle life, manual and pneumatic actuators are available, pneumatic actuator can rotate 360°, easy to connect the air line, can choose panel mounting or bottom mounting, normally closed pneumatic valve Position sensor available |
|
| 13 | Bellows-sealed Metering Valves | Return spring structure design with no dead travel allows for accurate and repeatable flow settings. Micrometer handle measures stem position in 0.02 mm (0.0008 in.) increments. Metered and regulating stem tips are available. Choice, modular design, lower maintenance costs |
|
| 14 | High Purity and Ultra High Purity Check Valves | Fully welded design with no internal threads. When the pressure difference is greater than 0.14 bar (2 psig), forward flow can be generated. Various port types are available. |
|
| 15 | High Purity and Ultra High Purity Regulators | Coupled diaphragm design improves safety, no springs in the wetted area, Hastelloy is the standard material for valve core and diaphragm, 316L stainless steel body is used for corrosive and toxic gases, and is suitable for oxygen environments |
