Dear experts: Does anyone know any manufacturers that produce zero-leakage valves? Eccentric, two-way, or three-way valves are all acceptable. Additionally, the switching speed should be just a few seconds – please!
Zero leakage is no problem, and the switching time for small-diameter valves is also fast; of course, it’s best to use it with an actuator!
Orbital ball valve: zero leakage, short switching time
For this issue, there should also be a standard for zero leakage – zero leakage at 100 MPa over 100 years – which is quite difficult to achieve. It’s better to specify the exact process parameters you need; saying generally that zero leakage is required won’t allow others to respond to you
Pneumatic butterfly valves can achieve zero leakage; equipped with pneumatic actuators, they also have a fast switching speed, allowing operation to be completed within a few seconds
Are there relevant materials and manufacturer contact information, as well as records of actual use?
How can I choose a model without any process requirements?
There are too many valves with zero leakage; specific parameters need to be specified
May I ask who you are? We have been struggling with these leak-free valves for a long time; they need to be switched on and off every 5 seconds, operating 24 hours a day. Waste gas flows through them, with a pressure of 5.5 kilograms and a temperature of 110°C. The volume of waste gas is approximately 10,000 CMH. Could you please recommend some suitable valves, as well as manufacturers and their contact information? Thank you very much!
Is the switch turning on that frequently? It is recommended to use forcibly sealed ball valves (track ball valves); the greatest advantage of such valves is that, during opening and closing, the ball separates from the valve seat, thereby eliminating friction between the ball and the valve seat.
