General purpose |
Please specify when ordering:
*Disclaimer: The above data is prepared based on common industry standards (ASME B16.34, API 598, API 602) for Y-pattern pneumatic diaphragm actuated globe valves . The multi-spring diaphragm actuator provides superior modulating control compared to piston actuators for this size range. Specific dimensions, materials, and actuator sizing may vary by manufacturer based on actual pressure and temperature conditions. The final technical agreement and certified drawings shall prevail.*
