Siemens MXG461.25-8.0U modulating magnetic control valve 5 W (1 in) M3P25G/C1

Product Description

Siemens MXG461.25-8.0U is a modulating magnetic control valve for closed-circuit hot and chilled water HVAC systems. The 1 in NPT cast iron valve provides a flow coefficient (Cv) of 9.3 and is fitted with a factory-mounted magnetic actuator that delivers positioning control and feedback. The actuator supports switch-selectable control signals and consumes 5 W; it features fast positioning and a fail-safe A to AB closed position when de-energized.

• 1 in NPT cast iron 3-way valve, flow coefficient Cv 9.3, suitable for closed hot and chilled water systems
• Factory-mounted magnetic actuator with inductive stroke measurement, fast positioning, and position feedback
• Switch-selectable control signals (0–10 Vdc, 2–10 Vdc, or 4–20 mA), power consumption 5 W, max temp 248 F, max pressure 44 PSI
