SVI II AP (Smart Valve Interface, Advanced Performance) is a high-performance digital valve positioner powered by a 32-bit microprocessor. It features a local interface that allows for easy control of a pneumatic actuator using a two-wire 4-20mA control signal. This device enables bi-directional communication utilizing the HART protocol, enhancing the overall efficiency of the system.
This instrument is designed with universality in mind, making it effortless to retrofit on Masoneilan or non-Masoneilan pneumatic actuators, which could be either single-acting or double-acting. Its flexible design offers a cost-effective and hassle-free solution to upgrading the control system.
The SVI II AP is equipped with advanced features such as digital position sensing and control algorithms, which guarantee exceptional accuracy and stability. This device makes valve control easier, enhancing the overall performance and productivity of the system.
Our product features a non-contact position sensing technology that allows for sensing through the housing. This means that there are no mechanical moving parts that enter into the main housing cavity, ultimately prolonging the life of the product.
In addition, the mounting procedure for this product is simple and easy.
Our product is designed to be easy, simple, and accurate to use. The LCD and pushbuttons are operable in all certified hazardous environments, making it a versatile product that can be used in different settings.
Quick and accurate commissioning is made possible with auto stops and auto tune methods. Additionally, this product is designed to fit many applications, either in rotary or linear settings, and can be both remote or local.
