Description
The Spirax-Sarco 3730196 1-1/2″ Piston Actuated Valve PF61G-2NC is a flow control part that regulates the passage of steam or process media through industrial heating and thermal systems. It operates using a piston-driven activation mechanism that respond to control signals to open or close the internal valve pathway, allowing controlled modulation of flow conditions. The assembly is built to manage pressure and flow stability during system operation under varying load demands. Installed within the piping network, it works alongside control and heating components in HVAC systems to assist with regulated distribution and operational balance throughout the system loop.
