Introduction to the Sure Flow Wafer Check Valve
The Sure Flow Check wafer check valve is a precision engineered, fully developed product at the forefront of pipe system technology. Sure Flow Check can be installed with confidence into offshore or onshore pipeline systems on product or service lines, wherever non-return protection is required.
Manufactured to meet API specifications, Sure Flow Check meets all the key criteria and in the vitally important area of comparative weights is actually lighter than other wafer check valves.
Sure Flow Check offers other operational benefits. It is light, tight, strong, compact and cost effective.
The Sure Flow Check Valve meets API 594 wafer check valve standard (except face to face dimensions of ASME 125 cast iron valves from 2-1/2” to 12” in which case they meet the Industry Standard).
