Siemens 257-02041 2" 2-Way N/O Pneumatic Actuator Valve Assembly 3–8 PSI 1/2" F X F Brass 4.0 Cv

The Siemens 257-02041 Pneumatic Actuator Valve Assembly is used to provide the control in the HVAC systems. It has a 2” 2-way valve and a pneumatic actuator for opening and closing the air passage and these are efficient. In its normally open (N/O) position, the flow can be controlled automatically depending with the needs of the system. It can handle large flow rates because of its 4. CV of zero, the body of this model is made of brass that makes it durable. The temperature range of 35°F to 250°F is suitable for most of the environmental conditions and the pressure range of 3-8 PSI is ideal for most of the applications. It is suitable to be used in HVAC systems since it increases the level of control, therefore the performance of the systems.
