  4. Max./Nor./Min Flow Rate: If gas(Nm³/h), steam or liquid(m³/h or kg/h)
  5. Density/Specific Gravity/Molecular W.
  6. Dynamci Viscosity: mPa.s(If viscous material is required)
  7. Compressibility/Critical press. Pc: For gas, Vapor press. Pv
  8. Special Requirements: Two phase flow, suspended particles?
  9. Valve Service: Such as vent valve, syngas control valve, vaccumn valve and so on
  10. Failure Position: Valve close/open/last
  11. Pipe Size/Material/Class

Quality – Every THINKTANK valve is designed by ourselves. We start with basic parts calculations, such as wall thickness, stem strength, top flange design and sizing, and so on. Taiwan engineers group design and calculation of valves from the inside out, if necessary we do FEA, CFD and other analyses to assistant.
The highest quality materials that we used in our valves, And combined with our surface hardening, proprietary components, and design features. Not only that, in 2021, we start a startup of an R&D company – Shanghai Myers Valves Co., Ltd, to do real testing before the mass production.
We never compromise materials or designs to save costs. Even we get lots of pressure from the market, we do believe time will tell the truth.
Performance – At THINKTANK, you are not paying for a simple name of products, you are buying the best performance valve for your application. We have 9 years of experience in control valves and self-operated pressure regulators manufacturing, 30 years of general valves, and pneumatic actuators manufacturing.
Flexibility – Whether it’s custom-designed valves or just a slightly modified one, we specialize in providing what our customers exactly want, not in selling a ‘COMPROMISE’. With a ‘Say Yes’ attitude, we provide proper engineering support, a standard test, and inspection. All products comply with ISO9001:2015 certificate, CE certificate, SIL3 functional system. We are small enough to be able to respond to our customers’ unique wishes.
Long-term value service – A good initial investment will bring you a long-term reward. Without years of trouble-free service, cost-effective spare parts. This means you may think the initial cost is more expensive, but actually bring you no worries equipment. We put everything on the table, not on the visible costs, but also the hidden costs.
A wise man said: Be very careful when choosing a new supplier. The disappointment of poor quality lasts much longer than the joy of low prices.

We are proud of our consistent words and deeds.
