Spence Engineering E-2 2 Inch E-Main Valve Ci

The Spence Engineering E-2 2 Inch E-Main Valve CI is a 2-inch cast iron pressure regulating valve designed for use in HVAC systems such as boilers, steam distribution lines, and other process control applications. This single-seat, generally closed valve uses balanced metal diaphragms for precision control and a backless construction to remove any possible leak spots. It functions by taking in a signal from an independent pilot, which modifies the diaphragm's pressure and opens or closes the valve to preserve the intended downstream pressure. Precise pressure control enhances equipment performance and efficiency by maintaining a constant pressure across the system.
