What are "Tight Shut-Off Valves"? We think this is a grey area where it needs to be further defined as "Absolute Tight Shut-Off" or "Zero-Leakage".
For Soft seated valves, it means Zero Leakage or ISO-5208 "Rate A" while for Metal seated valves, it can be ISO-5208 "Rate D".
We believe, Tight Shut-Off implies "Zero-Leakage" or "Absolute Zero-Leakage", technically, ISO-5208 "Rate A", without any controversy, even for Metal seated valves.
Can we meet ISO-5208 "Rate A" criteria with metal seated valves?
Yes, we can. With our product, ValvTechnologies metal seated valves, we can achieve ISO-5208 "Rate A". Made in USA, high quality valves with exceptional performance.
Pro-Mech Engineering is an exclusive distributor of ValvTechnologies valves in WA.
