The requirements for a Check Valve are simple. 1) Allow flow in one direction, and 2) Do not allow flow in the other direction. However, most engineers see Check Valves as a commodity item and think that they all work the same. The problem is that most Check Valves leak… and in most applications, this is a very big problem.
Quality check valves - especially when made of exotic materials - can be costly and have lead times that are just not acceptable.
At CVC we make thousands of Check Valves every year. These CVs perform under extreme conditions and are 100% tested for bubble-tight shutoff. We pride ourselves in making dozens of variations and in materials ranging from exotic metals to high-performance plastics. Even custom designed check valves can be built, tested and shipped within a matter of a few weeks - and at very reasonable prices. High pressures?? …no problem.
