ATHTS Series of Intelligent Control Valve use modular design,with advantages of impact structure and wide varieties.The varieties combination of the trim components, make it applicable for high pressure difference,high precision and low noise conditions to meet the different usage for customers’ requirements.The modular design,double-sides valve seat and compressing connection of the valve body, all greatly enhance valve sealing grade and its service life, which make it easy to repair and greatly increase its general performance. ATHA series muti-springs pneumatic reinforce actuator, makes the valve realize the conversion of normal close and normal open on site easily,the spring can be effectively protected from the corrosion to prolong the service life of actuator and convenient for customers operation. The actuator and the intelligent valve positioner are connected pipeless to strengthen the antisemitic performance,stability and precision adjustment, to meet to exactly control of the working conditions.
● Modular compact design: Compact structure, flexible combination of valve internalities, suitable for complex working conditions such as high pressure difference, low noise, and high precision.
● Double-sided reversible valve seat structure: The valve seat and the valve body are connected by compression, and both sides can be used. It features a high sealing grade and convenient maintenance.
●ATHA enhanced actuator: Multi-spring high-strength design, supporting rapid on-site switching between forward and reverse action modes.
● Slight positive pressure anti-corrosion protection: Effectively protects against the corrosion of springs and diaphragms, and extends the service life of the actuator.
● Direct connection technology without pipelines: The actuator is directly connected to the intelligent positioner, enhancing shock resistance, stability and adjustment accuracy.
● Intelligent and precise control: Combined with an intelligent valve positioner, it achieves precise adjustment of working condition parameters and long-term stable operation.
