Siemens Building Technology 371-03131 Normally Closed Control Valve Assembly Cv Stainless Steel - 2-Way 1 Inch 10

The Siemens Building Technology 371-03131 is a complete 2-way normally closed (N/C) control valve assembly designed for precise flow control in commercial HVAC hot and chilled water applications. This 1-inch Flowrite series valve assembly combines a bronze body globe valve with an electronic actuator for reliable proportional control.

Key Features:

• 2-way normally closed valve configuration with equal percentage flow characteristic
• 1-inch connection size with female x female (FxF) threaded connections
• 10 Cv flow coefficient for accurate flow rate control
• Stainless steel trim for enhanced corrosion resistance and durability
• Electronic actuator with dual control inputs: 0-10 VDC and 4-20 mA proportional control signals
• Non-spring return actuator design for fail-in-place operation
• 24 VAC actuator power supply
• 3/4-inch valve stroke for precise modulation

This factory-assembled valve and actuator combination is part of the Siemens Flowrite 599 Series, ensuring compatibility and reliable performance in building automation systems. The equal percentage flow characteristic provides excellent control at partial loads, making it ideal for heating and cooling coil applications where precise temperature control is required.
