MARELON VENTED LOOPS, Y VALVES
VENTED LOOPS
Installing one of our vented loops will ensure that fluids will not siphon from tank to
tank. Vented Loops are commonly used in the marine toilet system and engine cooling
system. The simple valve system incorporated in the top of the loop allows air to enter
the line when not in use, yet effectively seals as water or other fluid passes through.
Molded in Marelon
®
, neither vent nor loop will corrode. The duckbill one way valve is
designed to seal properly if particulate matter is present in fluids. The new MF-846
vent barb assembly option can be used in lieu of the standard MF-841 cap/duckbill.
This option allows venting to the outside of the hull via a 1/4”(6.35mm) hose.
‘Y’ VALVES & CONNECTORS
Forespar
®
‘Y’-Valves and Connectors are molded from Marelon
®
. Offering an improved, stronger handle design,
our valves are available in 1”(25.4mm) and 1-1/2”(38.1mm) barb size. ‘Y’-Valves are an essential piece of
equipment when the flow of water or other fluids are required to be conveniently diverted, as in a marine head
application where a holding tank is utilized. They are easily mounted to a bulkhead. The valves are operated by a
simple 120° movement. Positive stops are provided between positions. Replacement parts are available.
Our ‘Y’ Connectors can be used for connecting fluid lines. End plate may be removed for blockage relief etc.
O-ring seal ensures leak free performance and is safe under pressure working conditions up to 40 P.S.I. Available
with or without mounting flange.
IT IS NOT RECOMMENDED TO INSTALL Y-VALVES BELOW THE WATERLINE
