Hey guys. I need help. Sorry this might not go here... but i couldnt find a 'good' category to put it in. This is for an engineering project for college.Im looking for shielded core solenoid valves that can with stand 95-98% sulfuric acid. With this in mind not very many materials are usable, right now we are looking for HDPE (High-density polyethylene).The size of the valves and cost is unimportant. Main thing is finding someone who sells HDPE solenoid valves.For more clarification on what we are looking for, below shows a shielded core solenoid valve from ASCO. The more acidic resistant material they offer however is a FKM. Which can only withstand ~60% sulfuric acid solutions.
In practice, engineers do not use solenoid valves directly on chemical or process lines. They are bound to leak and cause danger particularly in your case of 98% sulphuric acid. Use a mechanical valve actuated by a motor (since cost is no issue to you) If an air supply is available, then you can use pneumatic diaphragm valve operated by a solenoid valve. Motorised valve has slower fixed open close time VS faster adjustable open close time for air operated valves.
