GRM SUCCESS STORIES:

Successful applications with our range of valves high performance coaxial cables
In this article we will talk about GRM success stories in fire simulation applications, ceramic manufacturing and blow molding. that have required our coaxial valves CO-AX®.
Fire simulator application for aircraft firefighters
GRM success stories
Application:
The Aircraft Fire Simulator is designed to recreate a number of different emergency scenarios, including incident indoor and outdoor fires and large-scale aircraft fuel spill fires, all managed by an adjacent control tower and a PC control station. Inside, a number of fires can be accessed through a series of doors on various levels, helping to play out realistic rescue scenarios.
Aircraft fire trainers are fully programmable and automatically respond to the application of extinguishing media, for a realistic fire response.
Fire simulations use clean burning propane. Alternatively, “dual fuel” fire simulations are available burning either kerosene for maximum realism or propane for environmental compliance.
Summary:
co-ax® valves are used to release propane or liquid fuel to the model airplane shown in the image. The fuel is ignited and the fire is extinguished by firefighting trainees. They use water to extinguish the flames. The water also prevents the model from becoming distorted. co-ax® valves are submerged under the gravel and water at the bottom of the pool.
Typical co-ax® valves used in this application:
Why are co-ax® valves the preferred choice?:
- Positive shut-off.
- Fast open/close speed < 100 milliseconds.
- Compact size.
- Valves (externally controlled) can be buried in a well.
Application in ceramic sliding
GRM success stories
Application:
A slip is a suspension in water of clay, sand and/or other materials used in the production of ceramic items, as bathroom accessories or as a non-slip coating on tiles. Sodium silicate is sometimes added to the slip to disperse the raw material particles. This allows a higher solids content to be used, or to allow a flowable slip to be produced with a minimum of water to minimize drying shrinkage, which is important during slip casting. The mixture of the slip is usually done in a blender, although it can be done with other types of blenders or even by hand.



Challenge:
Slip consistencymust be kept at the correct levels for production efficiency and product quality. A valve is used VMK 20 of 2/2 and one of 3/2 to fill the mold and purge after the filling process.
Summary:
The abrasive nature of the ceramic slip is a great challenge for most valves and often causes them to leak after a short period of time. Premature valve failure results in downtime and material waste. Unlike conventional valves, co-ax® valves handle abrasive, corrosive or viscous fluids better than ball, gate or butterfly valves. The repeatable speed of opening and closing is also important as it affects test time and output. The performance of co-ax® valves, which is not affected by operating pressure or wear, provides exceptionally consistent results.
Why are co-ax® valves the preferred choice?:
- Outperform ball or gate valves about 10 times.
- High cycle application.
- Repeatable opening and closing speed.
- Compact size.
Blow molding application
GRM success stories
Summary:
Blow molding is a manufacturing process in which hollow plastic articles, in this case plastic bottles, are formed.This specific blow molding machine uses an externally controlled coaxial valve (air operated) to operate. Air (500 psi) flows from port B to port A to form the bottle; once the plastic bottle is formed, the valve closes and air flows out from port A to port C through a silencer.
Blow molding plastic bottles requires accurate, repeatable, fast-acting control of air pressure. Downtime can be devastating and have a costly impact on all manufacturers. Most conventional valves struggle to provide accuracy, repeatability, and fast actuation for the most demanding applications. As a result, premature failure and operational problems can occur. These can be easily avoided by using a coaxial valve.
The externally controlled (air operated) co-ax® valve is pressure balanced with operating conditions that can be customized with suitable seat and seal materials for virtually any application. They are designed to be low maintenance and durable for a wide variety of applications, making them the best choice for systems that require reliable, high-performance valves with variable speeds. predictable opening and closing.
co-ax® valve used in this application:
Why are co-ax® valves the preferred choice?:
- Reduce downtime and maintenance cost.
- Designed for long life (high cycle life).
- Pressure balanced design.
- Adjustable opening and closing speeds.
At GRM we like to get involved in our clients’ projects and transform them into successful cases, regardless of the challenge, if you have any questions you can count on us.
