VSI Controls
VSI Controls™, a newly formed control valve company and a wholly owned subsidiary of PetrolValves TM , offers Customers an exciting alternative to procure general and severe service rotary and reciprocating control valve systems that provide a best-fit solution for their processes.
Portfolio at a glance
The control valve is the most important piece of equipment in modern process loops and control systems.
The operational conditions of fluid pressure, temperature and process dynamics require rigour in the analysis of intrinsic characteristics and in the selection of control valves to obtain efficient performance in a process control system.
We have assembled a range of products with the design, geometry and shapes that differentiate us in the speciality and severe service control valve market, in applications, such as superheated steam, high differential pressures, volatile, corrosive, dirty and erosive fluids, as well as solutions to eliminating cavitation and aerodynamic noise issues.
These shape and design characteristics, together with the use of noble materials, modern casting processes and advanced assembly and test technology, have allowed us to achieve an extraordinary level of capability and quality that is recognized by our customers all over the world.
The control valve offering includes Reciprocating Globe, Angle and Three-Way, Rotary Eccentric Plug, Double and Triple Offset Butterfly, Segmented V-Ball, Specialty Ball, Desuperheaters and Regulators. They come equipped with Double-acting spring return actuators and advanced digital positioners and provide the thrust, speed, accuracy and response to handle the most exacting applications.
Globe Control Valves
The G-Stream is the work horse of the reciprocating valve offering a modern design that incorporates an advanced clamped-in seat ring and a double upper guide system. It is available in a wide range of configurations and suitable for a wide variety of applications in the continuous process industries. Its double-acting spring-cylinder actuator ensures high actuation thrusts, pneumatic stiffness and excellent performance levels. The G-Stream is extremely versatile and can be supplied with several options to meet the specific needs of each application.
Alpha Trim Option
In applications with low and medium intensity cavitation, Alpha trim offers an economical and effective solution to minimize the harmful effects of this condition. The cage trim flow to close design, with staggered and diametrically opposed holes, directs the fluid jets towards the centre of the trim and away from metal surfaces. The use of hardened materials limits damage and erosion phenomena.
