Macon threaded connections are tapered type

(NPT) and should be made up according to industry

standards.

Inspect and clean pipe threads on both components

and piping.

Apply sealant, either pipe dope or tape to the threads.

If the product contains a union nut, remove the nut

and O-ring from the assembly. Place the union nut

over the pipe past the threads. Install the tailpiece with

a socket wrench.

Attach the body section to the other end of the piping.

Rotate the body using the hex flats nearest the joint

being tightened. Do not use a wrench on the main

body of the component. Position the body so that

the PT Port, PTV, Vent, Drain Valve and or Valve

Handle are in the proper position. Make sure that

the flow arrow is pointing in the direction of the flow.

After both ends of the valve are assembled to the

piping, reinstall the O-ring and tighten the union nut

hand tight and then tighten an additional quarter turn.

Care must be taken not to cut or pinch the O-ring.

THREADED VALVE CONNECTIONS

SWEAT VALVE CONNECTIONS

Macon products with sweat connections are

designed to be soft soldered.

Clean both copper tube and component ends with

sand paper and / or a wire brush, wipe clean and

apply flux uniformly.

If the product contains a union nut, remove the nut

and O-ring from the assembly. Place the union nut

over the copper tube past the flux surface. Install the

tailpiece and / or body on the copper tube with a

twisting motion to distribute the flux uniformly when

inserted. Position the body so that the PT Port, PTV,

Vent, Drain Valve and /or Valve Handle are in the proper

position. Make sure that flow arrow is pointing in the

direction of the flow.

A heat sink is required during soldering.

An appropriate heat sink is a wet rag wrapped around

the component closest to the solder connection.

Ball valves are required to be fully closed during

soldering to avoid deformation to the Teflon seat.

Valves should be allowed to cool before operating.

Apply heat with the flame directed way from

the center of the body . Do not exceed the rated

temperature of the component. Excessive heat will

damage internal components such as O-rings,

PT seals, and Teflon seats.

After the solder begins to melt, remove the flame

and continue to apply solder until a ring is formed

completely around the circumference of the joint.

While the joint is still hot, remove excess flux

and solder.

After both ends of the component have been

assembled to the piping, reinstall the O-ring and

tighten the union nut hand tight and then tighten an

additional quarter turn. Care must be taken not to

cut or pinch the O-ring.

The factory installed accessories (PT Port, PTV, Vent

and Drain Valve) will withstand the solder temperatures

if properly heat-sinked with a wet cloth.

INSTALLATION & OPERATING INSTRUCTIONS THREADED VALVE CONNECTIONS Macon threaded connections are tapered type (NPT) and should be made up according to industry standards. Inspect and clean pipe threads on both components and piping. Apply sealant, either pipe dope or tape to the threads. If the product contains a union nut, remove the nut and O-ring from the assembly. Place the union nut over the pipe past the threads. Install the tailpiece with a socket wrench.

INSTALLATION & OPERATING INSTRUCTIONS FLANGE VALVE CONNECTIONS Class 150 Valves are mechanically compatible with standard ANSI 150 lb, flat-faced or raised-faced steel flanges or with 125 lb, cast iron flanges. Appropriated gasket material must be used when installing flanged-mounted flow control devices (for example 1/16” thick ring type fiber filled gaskets). (Not supplied by Macon). All products have a flow direction arrow. Make sure that it is pointing in the direction of the flow.

INSTALLATION & OPERATING INSTRUCTIONS PRESSURE TEMPERATURE PORT (PT ) / PRESSURE TEMPERATURE VENT(PTV) PT Ports and PTV are typically factory installed. Factory installed accessories (PT Port, PTV, Vent and Drain Valve) are installed with a hydraulic sealant and should not be disturbed. If it is absolutely necessary to remove, tighten and/or adjust an accessory, it should be cleaned and resealed with new sealant and/ or Teflon tape. Care should be taken not to over tighten.

INSTALLATION & OPERATING INSTRUCTIONS AUTOMATIC BALANCING VALVES INSTALLATION There are no minimum straight-piping requirements for the inlet or the outlet. Valves may be installed in horizontal or vertical lines. The flow arrow on the valve body must be pointed in the direction of flow. Avoid placing the valve close to a pump discharge. Allow 10’ before the valve if possible.
