The document describes the AUDCO SLIMSEAL butterfly valve. It has an integrally molded elastomer body liner that is molded directly into the valve body bore and vulcanized in place, eliminating the need for maintenance. This integral molding allows for maximizing plasticizers in the elastomer formulation, ensuring a smooth surface and reducing friction and increasing strength of the seal. The SLIMSEAL valve requires no maintenance due to its molded liner that is not subjected to fatigue like loose liners, extending the life of the valve.
La válvula de mariposa es una válvula que puede ser utilizada para servicio ON/OFF o para regular el flujo. El mecanismo de cierre tiene forma de disco. El funcionamiento es similar al de la válvula de bola, ya que permite un cierre rápido con un giro de 90º.
The butterfly valve can be used for ON/OFF service or to regulate flow. The closing mechanism has a disk shape. Operates like a ball valve, allowing fast closing with a 90º turn.
Concentric type of butterfly valve is widely used for various applications. From Wafer to Lug, Flange, Universal, U section or AWWA types are all upon on request.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...DharmaBanothu
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

four phases by examining various levels of NLP and
components of Natural Language Generation,
followed by a review of the history and progression of
NLP. Subsequently, we delve into the current state of
the art by presenting diverse NLP applications,
contemporary trends, and challenges. Finally, we
discuss some available datasets, models, and

• Butterfly Valves are easy to open & close.
• They are easy to install due to their compact design & less space requirements at the place of installation.
• We provide Tight Sealing due to close interference between disc & liner. We also provide a Triple Stem Seal which prevents any
leakage and also any foreign particles from entering the valve.
• The flow control lever as well as the gear unit are designed such that very low torque is required for controlling the valve. Also, the
hand lever can be held in several positions whereby the disc position in valve is not affected by the flow pressure.
• These valves have very low pressure drop.
• We provide all our valves with CED coating which gives better corrosion resistance & hence gives long lasting life.
Maximum Working Temperature: 110°C (230°F)
MAIN FEATURES
• We have designed & manufacture the Lubi LBF series type of Butterfly Valves for General Utility Water applications as well as for
HVAC applications.
• It is a type of quarter turn valve which means that it can be fully opened or closed when the disc is rotated a quarter turn.
APPLICATIONS
The main applications of this valve is for general utility water
applications as well as HVAC applications.
The typical applications areas are as follow:
On/off isolation
Dead-end service/removal of down stream piping
Industrial process water piping
Municipal raw water intake
Municipal chlorinated water systems
Full vacuum
Aeration and blower applications.
