Spence Engineering E-2 1/2-250 2.5" Flanged Main Valve Cast Iron 250 PSI

The Spence Engineering E-2 1/2-250 Main Valve is used to regulate the circulation of steam, or hot water in pressurised piping elements which are used to control temperature. The valve body is made of cast iron, has a 2.5" flanged connection, and can handle a pressure of 250 PSI which allows fluid to flow or be blocked based on the system's needs. The pressure in the fluids forces the internal parts to control the flow of the valve chamber. The valve is used in steam and water heating systems to manage the movement of fluids.
