Product Description:
The SVI™ II AP is a state-of-the-art digital valve positioner with a local interface and advanced performance features. Designed with a 32-bit microprocessor, this instrument controls a pneumatic actuator through a two-wire 4-20mA control signal. It uses the HART® protocol, enabling bi-directional communication.
This valve positioner has a universal design that allows for easy retrofitting in place of existing analog positioners, even on Masoneilan or non-Masoneilan pneumatic actuators. It can be used on both single-acting and double-acting actuators.
Whether you're looking for greater accuracy or improved performance, the SVI™ II AP valve positioner is a reliable choice that can help meet the demands of any process.
Features:
Non-Contact Position Sensing Technology:
The non-contact position sensing technology enables sensing through the housing without the need for any mechanical moving parts to enter the main housing cavity. This technology helps to prolong the life of the sensing system and eliminates the need for frequent maintenance.
Simple Mounting Procedure:
The non-contact position sensing technology comes with a simple mounting procedure that makes the installation process easy and efficient. It eliminates the need for complex alignment procedures and minimizes the risk of errors during installation.
Easy, Simple, Accurate:
The sensing system is designed to be easy, simple, and accurate. Its LCD and pushbuttons are operable in all certified hazardous environments, making it a safe option to use in any situation. It also provides quick and accurate commissioning with auto stops and auto tune methods, ensuring reliable performance.
One Design Fits Many Applications:
The non-contact position sensing technology comes with a versatile design that fits many applications. It can be used for both rotary and linear movements, and can be installed either remotely or locally. This makes it a flexible and cost-effective solution for a wide range of industries and applications.

Applications:
Power Generation, Refining, Petrochemicals, Midstream Oil & Gas, Upstream Oil & Gas
The energy industry can be broadly categorized into several sectors, including power generation, refining, petrochemicals, midstream oil & gas, and upstream oil & gas. These sectors are responsible for energy production, processing, and transportation at various stages of the energy value chain.
Each of these sectors has key applications that enable the efficient and effective operation of facilities. For example, in power generation, key applications include steam turbine generator, condenser, cooling tower, reactor building, and turbine building. Similarly, in petrochemicals, applications such as distillation, hydroprocessing, reforming, cracking, secondary, blending, quenching & fractioning, and charge gas compression are crucial for the processing of raw materials into useful end-products.
The upstream and midstream sectors involve oil and gas exploration, production, and transportation. In these sectors, applications such as pipeline integrity, operations, dehydration, refrigeration, liquefaction, loading/shipping, regasification, and auxiliary operations are important for ensuring the safe and efficient delivery of hydrocarbons to end-users.
