Description
Siemens 277-05980 pneumatic actuator assembly is used to control the flow of fluid in HVAC systems and 2 way, normally open valve with a 2.5 inch flanged connection and a strong 8 inch pneumatic actuator able to withstand 125 PSI pressure. Features 63 Cv flow capacity that can effectively handle liquid. The pneumatic actuator is forcing open and closing the valve. Fluid flow is allowed until an actuator is signaled to close the normally open arrangement. This exact control is necessary for peak system performance and energy efficiency. The valve is designed for severe HVAC conditions is reliable in the long term. The 63 Cv flow capacity is sufficient for effective fluid management and lower energy use.
