Description
Siemens 277-03130 is a pneumatic actuator assembly for controlling fluid flow in HVAC systems, 2 way, normally closed valve, trim 3/4″ stainless steel, temperature range 20°F to 250°F. Compressed air power opens and closes the valve powering the pneumatic actuator. The actuator moves valve stem and allows the fluid to flow the air pressure. It generally closes and controls fluid flow precisely and responsively, thus optimizing system performance. The stainless steel trims for corrosion resistance and longer performance demonstrated on hardy HVAC applications. Contributes to energy efficiency by controlling fluid flow in line with system requirements. It controls fluid flow exactly to give system an optimal performance.
