1 1/2″ LARGE BRASS MANIFOLDS FOR 5/8″ & 3/4″ PEX & PEX-AL-PEX TUBING, 2–12 LOOPS
MrPEX 1 ½” Brass Manifold is made from high quality alloy extruded and chrome plated after machining, and is offered in 2 through 12 loop configurations. The manifold comes mounted on brackets and it is equipped with high flow ball valves provided with thermometers, manual air vents and fill/drain valves. The SUPPLY (upper) manifold is fitted with balancing flowmeters with readable range of 0 to 2 GPM that allow flow adjustment of each individual loop. The flow meters have a brass body and the sight glass is made from temperature and impact resistant plastic material, all components are anti-freeze resistant up to a 50% mix. The RETURN (lower) manifold, has manual on/off valves that controls the flow for each individual circuit. The manual knob can be removed to accommodate the MrPEX actuators (part# 5120700 & 5120701). Supply and return mains can be connected from either left or right sides. The manifold comes ready for a left-hand connection. Connection from the right can be done by removing the manifold body from the brackets and flipping them over.

MrPEX® 1 1/2” Brass FOR 5/8” AND 3/4” PEX AND PEX‐AL‐PEX TUBING, 2‐12 LOOPS
MrPEX® 1 1/2″ Large Brass Manifolds are made from high‐quality extruded brass and offered in 2–10 loop fully assembled manifolds. The supply body has balancing valves with adjustable flow‐meters for flows up to 2 gpm per loop. The return body is equipped with on/off valves. The return balancing valve disc is designed to enable exact adjustments of small flows while s????ll being able to handle large flow with minimal resistance. The branch Cv value is 1.3 and the manifold body accommodates flows up to 20 gpm. Manifolds are mounted on brackets ready to mount. Inlets comes with a 1 1/4″ female NPT union ball valve and end caps feature vent and fill/drain. The branches have EK 25 (Eurokonus) connection.
