Introduction
Reliable and comprehensive data communications are essential elements in the modern process plant. Plant managers today demand access to more information, more quickly than ever before. Process operators must have the ability for full control at all times, 24 hours a day, 365 days of the year. Maintenance managers need the information required for efficient asset management.

To meet these requirements, design engineers incorporate field communication

As a manufacturer, supplier and solution provider, Rotork India Pvt. Ltd. goes from strength to strength. In a little over 40 years the company has grown from a joint venture into what has today become a cornerstone of Rotork’s global business, so it not surprising that the company has some ambitious plans for the future. The Valve World India Journal recently caught up with Mr. Ravi Shankar, Managing Director of Rotork India Pvt.Ltd. at his office in Chennai, to discuss such topics as

A intelligent asset management system currently under trial will analyse information from valve actuator dataloggers, and relay it to operators to allow accurate prediction of maintenance and repair work, says Liam Jones of Rotork.

Intelligent asset management technology could save operators costly site downtime, while providing the opportunity to gain greater in-depth knowledge of the condition and status of their actuators and valves.

The asset management principle is

There are many good reasons for introducing a level of automation to river sluice gates which are old and manually operated. Sluice gates are vitally important for defending against flooding during periods of persistent rainfall, when swift and reliable operation can prevent serious disruption and damage to property. Alternatively, during periods of drought, sluice gates play an important role in maintaining the river level.

The automation of a sluice gate is a relatively simple op

Introduction

Rotork Instruments, the youngest division of Rotork, has been established by a string of acquisitions in the last seven years. There is a gap between actuators and control systems that we intend to fill with tried and tested packaged solutions and new innovative concepts that deliver value to our customers."

According to Andy Filkins, Business Development Director of Rotork Instruments, innovation is the key word for Rotork Instruments and t

Overview

Low emission pneumatic controllers and overall carbon footprint reduction are today`s hot topics for electro-pneumatic control systems. As shown in the chart below, pneumatic controllers have been viewed as a significant source of greenhouse gas emissions!.

Since natural gas is often an abundant pressure source, it is common practice to tap this gas as the supply for the pneumatic instrumentation. When utilising this source, however, the allowab

Rotork has extended its CMA range of compact modulating actuators with new sizes specifically designed for reliable automation of larger linear control valves.

The new actuator is capable of a maximum 4,500 lbf (20 kN) seating thrust. The new sizes increase the CMA range modulating thrust performance to 3,000 lbf (13 kN) with a 114.3 mm (4.5”) stroke length for the automation of larger valves with higher pressure ratings. The combined performance of the CMA and the larger CVA

Introduction

The natural gas industry commonly uses pneumatic devices powered by pressurised natural gas as valve controllers and pressure regulators. However, these devices are one of the main sources of vented methane emissions inthe industry, with 51 billion1 cubicfeet released peryear in the production sector alone.

These levels can be reduced or even completely eliminated by replacing high bleed and low bleed devices by retrofitting existing natural
