371-03170

The 371-03170 control valve assembly by Siemens is part of the Flowrite 599 Series and is engineered for durability and reliability in fluid applications. With a compact valve body style of stroke-globe, this unit measures 2 inches in size and is designed to operate in a 2-way normally open configuration.

Weighing in at 14.9 lbs, this assembly is constructed with a bronze trim that contributes to its robust performance and longevity. The flow characteristics adhere to an equal percentage profile, which improves control precision across varying flow conditions. Capable of achieving a flow coefficient of 40 Cv, this valve is adept at managing fluid passages effectively.

The actuator type is electro-mechanical and features a non-spring return action, ensuring it returns to a safe state when signals are not present. Control of the valve is facilitated through either a 0 to 10 Volts DC or a 4 to 20 mA control signal, making it versatile for various applications. The actuator is powered by a 24 VAC supply, allowing straightforward integration into existing control systems.

Moreover, this valve assembly maintains a low leakage rate classified as ANSI Class IV, which equates to about 0.01% of the Cv. When considering pressure handling, the valve conforms to ANSI Class 250 standards, ensuring it can sustain positive pressures during operation. This combination of features makes the Siemens 371-03170 a favorable choice for applications requiring reliable flow control.
