Zero Leak Transfer Valves 3-Port and 6-Port Advanced Designs

Founded in 1897, Wm. W. Nugent & Co. (Inc.) dedicated itself to providing engineered solutions to oil system problems. This dedication continues today with the introduction of our improved line of Zero Leakage 6-port Transfer Valves and new complementary line of Zero Leakage 3-port Valves. These user-friendly valves are specifically designed to divert the flow of liquids from one system to another easily, reliably, with absolutely no side-to-side leakage and no interruption to flow.

ASME Code Filters and Strainers

ASME Code Filters and StrainersThese dual circuit, 3-port and 6-port transfer valves are designed for assembly between filters, strainers, and heat exchangers where continuous service and positive shut-off are necessary. These valves feature an exclusive internal quad-ring design, eliminating side-to-side leakage even at test pressures to 1000 PSI. The operation of our Zero Leakage Transfer Valve is much simpler than other valves because there are no pads to seat and unseat and no locking pins to lift. Our internal arrangement is free of all springs, pins, and levers that break loose and cause severe damage to the costly equipment it was meant to protect. After equalizing the pressure, simply rotate the handle to transfer the fluid from one vessel to the other. Available in 1-1/2”, 2”, 3”, 4” sizes. Designed for operating pressures to 665 PSI. A steel body and iron rotor are standard; stainless steel rotors or all stainless steel construction is optional.
