ISO 6164 Ball Valves

ISO 6164 ball valve is made in accordance to ISO 6164-1 (ISO250) and ISO 6164-2 (ISO400). Two-way high pressure ball valves are designed to use as on/off flow devices for hydraulic applications and have a round shape body. The size range available is from DN13 to DN80, which is from 1/2” to 3”.​

The working pressure is available from 100 bar to 400 bar, subjected to valve size diameter. The final maximum pressure rating of flange connection is determined by the overall working pressure of the pipeline.

What are ISO 6164 Ball Valves?

1. What is ISO 6164 ball valve? 
​
ISO 6164 is a valve design to use in high pressure hydraulic systems. The valve working pressure determines by valve body size and when the body size goes bigger, the valve operation pressure goes lower. The final overall running pressure is determined by pipe or tube rating and flange connected. The working temperature ranges from -10°c to 100°c, subjected to material combination of the complete ball valve.

3. How do you stop a ball valve leak?

When larger ball valve size has to be activated at full differential pressure, a smaller ball valve can be used before activation in order to equalize the pressure. A combine bypass within the flange valve body to provide less leakage points compared to a pipe installation solution. 
​

• Both main valve and bypass valve can be offered with locking device features or any other accessory like limit switches or actuators.
• Bypass valve is a standard manifold mounting PKH valve which can be easily removed, replaced and maintained. 
• Bypass manifold mounting valve provides bubble tight shut off application.

4. What are ISO 6164 ball valve accessories? 

Valve can be customised with additional accessories options on request as per below:

• Locking devices 
• Actuators packages 
• Mounting holes 
• Alternative lever designs and materials 
• Position switches 
• Special combination 
• Detent

5. What is a ISO 6164 ball valve used for?
