Siemens 599-01110 1/2" Control Valve Body N/C 4.0Cv Equal Percentage

Siemens 599-01110 Control Valve Body N/C is a 2 way control valve for precise fluid flow regulation in HVAC systems. It has an equal percentage flow characteristic, i.e., the flow rate varies exponentially with valve travel, thus assuring accurate control. It has a spring range of 3-8 PSI, so it is sensitive to changes in control signal. It is made from durable brass, robust and reliable. It is 1/2" valve size and it is compact and easy to install. This type of control valve is used when operating heating and cooling equipment within fan coil units, air handling units, and terminal units. The equal percentage characteristic guarantees performance under variable load conditions, improving energy efficiency and system reliability.
