The SVI™ II AP (Smart Valve Interface, Advanced Performance) is an innovative digital valve positioner that is equipped with a powerful 32-bit microprocessor. This state-of-the-art instrument features a local interface that enables users to control a pneumatic actuator using a two-wire 4-20mA control signal. The SVI II AP is designed with bi-directional communication using the HART protocol, allowing for seamless integration with various control systems.
One of the notable features of the SVI™ II AP is its universal design, which ensures that the instrument can be easily retrofitted in place of existing analog positioners. The instrument is compatible with both Masoneilan and non-Masoneilan pneumatic actuators, whether they are single-acting or double-acting. With this functional design, users can improve valve performance and reduce maintenance costs, without the need for significant system modifications.
The SVI II AP is a reliable and efficient solution for valve control, offering high precision and accuracy. Its advanced technology provides enhanced performance over traditional positioners, delivering higher productivity and profitability for industries such as oil and gas, petrochemicals, and energy.
The Non-Contact Position Sensing Technology is an innovative solution that allows sensing through the housing, without any mechanical moving parts entering the main housing cavity. This approach significantly prolongs the life of the device, providing high reliability and low maintenance requirements.
Furthermore, the mounting procedure of this technology is straightforward and easy to follow, making it a perfect fit for many applications. This solution enables simple installation, reducing the downtime and increasing productivity.
The Non-Contact Position Sensing Technology offers an easy, simple, and accurate way to operate in all certified hazardous environments. The LCD and pushbuttons are fully operable in these environments, providing reliable and safe control of the device.
Additionally, the commissioning process is quick and accurate, with auto stops and auto tune methods ensuring an optimal setup. The design of this technology is versatile, allowing it to fit many applications, whether you require rotary or linear measurements, local or remote positions.
