Y-Calibur® – The DFT® Y-Calibur® Check Valve is specially designed with reliable and versatile service in mind. The Y-Calibur® valve is a silent, in-line check valve that is fully repairable—this low-maintenance product helps keep repair costs down, and is suitable for various fluids, pressures, and temperatures.
