ValvTechnologies is an exclusive distributor of in-line check valves for nuclear applications and licensed manufacturer of ASME III and safety-related check valves. Designed to prevent “water hammer”, the spring-assisted, in-line design featured in all DFT® check valves ensures that as the forward flow in a pipeline decreases, the disc begins moving closer to the seat. By the time the flow stops, the disc is closed against the seat, preventing flow reversal. This prevents the valve from slamming closed, causing “water hammer” and the resultant noise and damage to piping systems.
