K Controls Ltd

The new K Controls "Knowledge" blog at www.k-controls.info features regularly updated product and application news, the course "Pneumatic Valve Actuation" and other free training material.

We hope you find it a useful resource that you will want to bookmark and share with others..

K Controls designs and manufactures products that provide safe, reliable and accurate monitoring or control of actuated valves used in the process industries. Many applications are in hazardous or hostile environments. The company operates an ISO 9001 quality system that also complies with the relevant parts of the ATEX 95 Directive 94/9/EC. All our products conform to standards that will ensure compliance during your plant safety audits.

■ Switchboxes with corrosion resistant enclosures ■ ATEX and IECEx certified products for use with hazardous gasses and combustible dusts ■ Switchboxes with high (+300 deg C) or low (-50 deg C) temperature capability ■ Switchboxes IP68 for submersion ■ Versions with integral solenoid for parallel wiring or connection via remote I/O systems ■ Integrated fieldbus compatible versions for AS-interface® and DeviceNet™ ■ Fieldbus compatible versions for PROFIBUS® PA or FOUNDATION™ FIELDBUS via valve couplers ■ Position transmitters for 4-20mA, HART®, PROFIBUS® PA or FOUNDATION™ FIELDBUS ■ Linear or rotary solutions

We can also supply your positioner requirements.

Specialised advice, design excellence and an ability to exactly customise products to match your requirements all help minimise the time and money spent on product sourcing, specification, installation, commissioning and maintenance.

K Controls has also developed two valves for specialised applications:

The K44 "Checktite" three piece swing check valve has been designed to complement three piece ball valves and is used on chemical, petrochemical and pharmaceutical process lines as well as gas, oil and water service lines. It is used wherever unwanted flow reversal has to be prevented.

Available in 316 stainless steel or carbon steel with stainless internals, in sizes from 0.25'' (8mm) to 2'' (50 mm), the K44 "Checktite" employs a three piece body and end design secured by four bolts (as widely used with ball valves).

This design facilitates quick and simple installation and enables the valve body to be swung away from the line for easy inspection, cleaning or maintenance. Both the cracking pressure and pressure drop of the K44 are significantly lower than those of most other check valves.

K Controls has also developed a Z Series stainless steel butterfly valve for high temperature automotive exhaust gas applications The Z Series valve is frequently used to regulate the back pressure of exhaust gases during engine testing

The valves do not give a tight shut off but they can regulate the flow of exhaust gas streams at temperatures as high as 750 degrees C. The maximum differential pressure at this temperature is 3.5 bar g.

The wafer pattern valves are manufactured in sizes 2'' to 16''.

They can be supplied to fit between different flange types eg ANSI 150, PN16 etc.

The valves can be manually operated (screw lockable in any position) or pneumatically or electrically actuated with positioners.
