Gas leaks and explosions may result. Do not install in systems which exceed the ratings of the valve. • Avoid installations where valve may be exposed to excessive moisture, corrosive fumes, vibration, high ambient temperatures, elements, or high traffic areas with potential for mechanical damage. • Valve assembly location must be within ambient ratings of actuator. If the temperature is below -22°F, a heater is required. • The valve assembly will require heat shielding, thermal isolation, or cooling at the actuator if combined effect of medium and ambient temperatures (conduction, convection, and radiation) is above 122°F for prolonged time periods.• Strainers should be installed before coil and valve.• Visual access must be provided. Assembly must be accessible for routine service. Contractor should provide unions for removal from line and isolation valves.• Avoid excessive streses. Mechanical support must be provided where reducers have been used and the piping systems may have less structural integrity than full pipe sizes. • Vertical pipes with valves and dual actuators may require support for linkage.• Sufficient upstream and downstream piping runs must be provided to ensure proper valve capacity and flow response. Five diameters in each direction are reccomended. • Life span of the valve stems and packing is dependent on maintaining non-damaging conditions. Poor water treatment or filtration, corrosion, scale or other particulate can result in damage to trim components. A water treatment specialist should be consulted.1. Inspect shipping package, valve, linkage, and actuator for physical damage. If shipping damage has occurred, notify appropriate carrier. Do not install.2. If this is a replacement, remove the existing valve, linkage, and actuator from the piping system.3. If actuator and linkage are removed, they must be reinstalled correctly. The actuator must be rotated so that the valve seats properly for close-off. 4. Install valve with the proper ports as inlets and outlets. See piping charts on next page. Check that inlet and outlet of 2-way valves are correct; check that the “A”, “B”, and “AB” ports of 3-way valves are piped correctly. Flow direction arrows must be correct. 5. Blow out all piping and throughly clean below valve installation.6. clean male pipe threads with wire brush and rag. If threads have been damaged or exposed to weather, running a tap or die over the threads may straighten them. Clean pipes, threads, and valve threads before installation. Check for any foreign material that can become lodged in trim components. Strainers should be cleaned after initial startup.7. Pipe sealing compound may not be applied to either flange or gasket.8. Flanged bodies must be used with flanges which are rated for the service. 125 lb. flanges have flat faces and may not be bolted to raised face flanges. Gaskets rated for the medium and temperature-pressure must be used. 9. Valve must be installed with the stem towards the vertical, not below the horizontal.10. Tighten bolts alternatively and evenly around the flange.11. 2-way valve Normally Open (NO) or Normally Closed (NC) configurations must be verified by examining both the mechanical drawings and the valve and actuator.12. 3-way valve Normally Open (NO) or Normally Closed (NC) configurations for the control port and the bypass port must be verified by examining both the mechanical drawings and the valve and actuator. Check specifications for every application to be sure of ports and designations. U, L, and C designationsU is for Upper, the control port. L is for Lower, the bypass port. C is for Common.Viewed with the bonnet upwards ad the U port on the left, the L port is the bottom port, and the C is the right port. With the stem up, L is open to Common. With the stem down, U is open to Common.4Flanged Globe Valves 2½” to 6”Installation InstructionsFlow arrow shown on rear of valveFLOW PATTERN – Flow Pattern is Marked on ValveG6 2-way ValveStem Up = Open A to ABG7…D 3-way Diverting ValveStem Up = Open AB to BAABBG7 3-way Mixing ValveStem Up = Open B to ABABAB VALVE ASSEMBLY SET-UP - Specify Upon Ordering2-WAY VALVENON-SPRING RETURNSTAYS IN LAST POSITIONEV, RV SeriesNC: Normally closed A to AB, valve will open upon increase in signal/power.Note: To change valve to A to AB open, reverse the directional switch in actuator.NO: Normally open A to AB, valve will close upon increase in signal/power.Note: To change valve to A to AB closed, reverse the directional switch in actuator.SPRING RETURNNOTE FAIL POSITIONAFB, AFX SeriesOn/OffNO/FO: Normally open A to AB valve will drive closed.
