298-03149

The Siemens 298-03149 control valve assembly is designed to provide effective modulation in fluid control applications. Featuring a 1-inch valve size, this assembly integrates a GCA161.1U model actuator, which is an OpenAir electronic rotary actuator partnered with a 599-03609 linkage for precise operation.

This model is capable of handling a maximum flow coefficient of 10 Cv and is engineered with a 3-way port configuration that functions as normally closed. The valve achieves linear flow characteristics, allowing for consistent and controllable movement of the media. Its stainless steel trim promotes longevity and efficient performance even in demanding environments.

Connections are configured as female to female (NPT), ensuring compatibility with existing piping systems. The control signal for the actuator can accommodate either a range of 0-10 Volts DC (with a maximum of 35 Volts DC) or a 4-20 mA signal, providing flexibility in system integration. Operating voltage for this assembly is rated at 24 Vac with a tolerance of ±20% or 24 Vdc with a tolerance of ±10%.

This device performs effectively across a significant temperature range, from -32°C to 55°C. In terms of humidity, it can sustain a maximum level of 95% relative humidity without condensation. For logistics, the valve can be safely stored or transported within temperatures between -32°C to 70°C, making it suitable for various operating conditions.
