Description
Overview
The Sprecher + Schuh 31924 is a heavy-duty 3-way flanged globe valve assembly engineered for precision flow control in commercial and industrial HVAC hydronic systems. Combining a robust 3″ bronze-trim globe valve body with an integrated non-spring-return motor actuator, this assembly delivers reliable, repeatable performance across demanding building automation and process control applications.
Valve Features
- 3-way globe valve configuration for mixing or diverting service
- Flanged end connections for secure, leak-free installation
- Bronze trim construction for corrosion resistance and long service life
- 3″ valve body size
- Flow coefficient: Cv 91 for high-capacity flow applications
Actuator Features
- Non-spring-return motor actuator — maintains last position on power loss

- Supply voltage: 24 Vac / 24 Vdc
- Control signal: 4–20 mA (500 Ohm input impedance)
- Control signal: PWM (1,500 Ohm input impedance)
- Additional control modes: Floating point and On/Off
Control Signal Compatibility
- 4–20 mA analog signal — 500 Ohm impedance
- PWM signal — 1,500 Ohm impedance
- Floating point (tri-state) control
- On/Off switching control
Applications
- Chilled water and hot water coil control in AHUs and fan coil units
- Building automation system (BAS) integration
- Commercial hydronic heating and cooling distribution
- Industrial process flow control
- Variable flow and constant flow hydronic systems
Why Choose the Sprecher + Schuh 31924
The 31924 valve assembly ships as a complete, pre-assembled unit — eliminating field pairing and compatibility concerns. The non-spring-return actuator retains valve position during power interruptions, protecting system integrity. With four compatible control signal types and dual voltage compatibility (24 Vac/Vdc), this assembly integrates seamlessly with virtually any modern BAS or DDC controller.
