OVERVIEW
TT-HLS Series Small-Port Single Seated cast iron Control Valves are designed for heavy duty service. The valve body, having an S-shape flow passage that features
low pressure loss, allows a large flowcapacity,rangeability, and high accuracy flow characteristics.
The valve plugs are available in wide range of Cv values. The flow shutoff performance complies with the IEC or JIS standards. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator leaded with multiple springs.
The model TT-HLS Control Valve are widely applicable for reliable control of small flows in high or low temperature, high pressure process lines.
