The D200 standard valve is designed to keep a high level of purity of the gas. The gas does not come into contact the valve operating mechanism thanks to its diaphragm technology. The D200 is suitable for High purity, flammable or toxic gases, used in many fields of applications, as calibration, laboratories, research centers or in the food industry.
Key advantages
- Soft seat sealing arrangement offers low operating torque
- Valve seat captivated to avoid extrusion and valve blockage
- High leak tightness integrity through diaphragm sealing
- High performance thrust pad
