Stock Industrial Temperature Control Valve Amot 3 Way Thermostatic Valves and Samson 3730 Valve Positioner Price

Samson 3730 electropneumatic positioner (HART-enabled) with Amot thermostatic 3-way valve for temperature regulation. The Amot valve provides automatic, fail-safe mixing or diverting based on fluid temperature, while the Samson 3730 offers smart control on a separate modulating valve in the same circuit. It is a common solution in engine rooms, cooling systems, and process plants where both safety and precision are important.

• Amot valve: no electricity required, wax element for reliable thermal response
• Samson 3730: HART diagnostics, local interface, auto-setup
• Fail-safe temperature override (Amot)
• Precise positioning of control valve (Samson)
• Wide temperature setpoint range (Amot)
• Low maintenance on both devices

Q: Does Amot valve need power supply?

A: No – purely mechanical/thermal.

Q: Can Samson 3730 directly drive Amot valve?

A: No – Amot is self-contained. The combination is usually for hybrid loops.
