Kia ora! Year 2011 had been a very busy and interesting year for GICOB Flow Control. While coping with the continuous after shocks, we continue to expand our presents in the industries. We are pleased to announce that we now have now added more materials options for our client. GICOBTM range of valves now available in exotic materials such as Titanium, Incoloy (A265), Al Br Ni (UNS C95800), Hastelloy (C276, C4, G30, C), Monel.
We would like to thank our valuable customers for trusting our product and we will try our best to keep our products and services to the highest standard.

A double block and bleed valve is normally utilized in a situation where two processes required positive isolations which occasionally both processes require integration. A vent valve is located in between the two isolation valves to detect leakage while the line is isolated and also acts as a prevention of pressure build up from the main process forcing into the secondary process line.
Designing the internal parts of a double block and bleed valve is crucial. Despite having tight seal surface, it must also ensure highest safety enhancement for the operators and the equipment where it is installed. KSV instrumentation double block and bleed has a built in anti blow out feature that prevent stem blow out while operating the valve in service. It also has a locking device that prevents valve assembly from coming off their seat. Whether it’s API 607 firesafe standards or NACE MR01-75, KSV double block and bleed can meet these industrial standards.
Our KSV double block and bleed offers optional injection or sampling valve design, providing double block and bleed protection with either injecting fluids into the process or taking sample from the process. An optional integrated check valve as extra safety feature is available on all KSV injection DBB to prevent backflow of process fluid into the injection line. In KSV, we understand that not all process line size are the same, and not all installation locations are ideal, therefore we welcome our customer to discuss their difficulties with us and we can custom made to suit the situations. Customization includes materials, probe length, size and configuration. For more information, contact your authorized KSV representative today.

22 February 2011 12:51pm, a day which all New Zealanders and countries around the world watch mother nature taking its force on Christchurch, Garden city of New Zealand. A month had passed since the 6.3 earth quake, feeling of emotions, sadness, lost and grief continues to haunt many Cantabrians.
As part of the community, GICOB Flow Control has put our feet together assuring our valuable clients that we are now up and running. We are back to the routines! Like many of Canterbury business, we are hit hard by the aftermath of this disaster, but we’ll stand strong and move on more aggressively to build a sound business in years ahead.

Case Study: Centrifugal pump overheated?
Running a centrifugal pump lower than the recommended flow rate will heat up pump due to friction and thus decreases its reliability and performance. Pumps heat up when quantity of fluid is low causing it to heat up through friction and hydraulic losses. This will cause seals, bearing failure hence lead to production downtime. Cavitation also occurs when the impeller of the pump has below minimal fluid flow to drive. Therefore in order to make sure your centrifugal pump has minimal flow to keep it working happily, conventional way is to install a series of check valves, control valve, solenoid valve and meters to keep minimal fluid flow through the pump. It detects any upset of the system to ensure the pump is protected from above mentioned failure.
However, there’s a better way or one should say a more economical way to deal with minimal fluid flow of the pump. Introducing GICOB’s GRC model Automatic Recirculating Control Valve. The principle is fairly simple: “Keep the conventional system within a valve”.
During the start up of the pump, the by pass of the valve will fully open to ensure recirculation of the flow through the pump. Regulating of the by pass flow will start when the main flow increases. Once main flow exceed the minimal flow, the by pass line shut off completely allowing 100% main flow in the process.
All these are controlled mechanically within the valve itself. The benefit of GRC compare to conventional by pass system are:
1) GRC valve substitutes all the valves, metering system and piping resulting in a significant advantage in installation time and cost. It also provides easy maintenance and performance integrated in a single component.
2) In contrast to the sophisticated arrangement of system and power requirements of a conventional bypass, the GRC is a simple and worthy piece of equipment which provides long-term reliability with little or no maintenance.
3) GRC will dampen low-frequency pulsations from the impeller hence give better protections on pump as well as the whole system. 4) Save energy as it’s in regulating control through it’s self acting mechanical parts.

4th September 2010 4:35am, Christchurch was hit by earthquake measuring 7.1 on the Richter scale. The Christchurch earthquake was felt throughout the South Island of New Zealand. Most damage was suffered within a 50km radius of the quake's epicentre in Darfield at a depth of 33km has left large parts of the area without power, water or telephones. Some houses were totally destroyed. Estimated damage were up to NZD4billion.
The community of Christchurch has come together in this difficult moment as many has worked around the clock helping each other. We would like to express our gratitude to our PM, Mayor, Civil defense team, emergency response team in Christchurch and around the nation for giving their help to our community. Thank you.
In addition, our staffs would also like to thank our overseas distributors for sending their warmest condolences to our community. We appreciate your support and encouragement.
