High Pressure Tied Diaphragm Regulator - 959 & NPR959 Series
Brand: Parker HannifinThe 959 regulator can be used in a wide range of application conditions.
The 959’s design characteristics such as a tied diaphragm and a unique compression member give you precise control with added safety and consistent performance over the operational range of the regulator.
Superior internal component alignment and contamination control make the 959 the perfect solution for your pressure regulator needs.
Features- Tied diaphragm for added safety
- Unique compression member loads the seal to the body without requiring a threaded nozzle or additional seals
- Metal-to-metal diaphragm-to-body seal assures high leak integrity
- Adjustment range spring may be replace without breaking diaphragm seal to body and exposing the wetted area to contamination
- Cleaned for O2 service is standard
