Iftemperature is below -22°F a heater is required.The valve assembly will require heat shielding, thermal isolation, orcooling if combined effect of medium and ambient temperatures – conduction, convection, and radiation– is above 122°F for prolonged time periods at the actuator.•Following standard procedure, a strainer should be installed before thecoil and valve or in another appropriate place in the system.•Visual access must be provided. Assembly must be accessible for routineschedule service. Contractor should provide unions for removal from line and isolation valves.MountingThe fl ange allows the actuator to be either parallel or perpendicular to thepipe; there are four orientations possible.If fi eld installing a spring return actuator, disconnect power and allow actuatorto spring closed. Flip actuator over if necessary to achieve proper rotationdirection. DO NOT USE THE REVERSING SWITCH TO DO THIS.Two-Way Valves MountingFor NORMALLY CLOSED operation:The ball of the valve must be rotated so that the ball is CLOSED to flow. Theactuator should be mounted with the clamp fully rotated CW (R). Spring return actuators will show the CW (R) symbol near the clamp and positionindicator. Depressing the gear release to move the clamp rotates non-springreturn actuators.For NORMALLY OPEN operation:The ball of the valve must be rotated so that the ball is OPEN to flow. Theactuator should be mounted with the clamp fully rotated CCW (L). Spring return actuators will show the CCW (L) symbol near the clamp and positionindicator. Depressing the gear release to move the clamp rotates non-springreturn actuators. There are marks on the top of the valve stem, which indicatethe port directions.Do not force. Do not use the actuator to turn the pipe or the stem. Do not use any toothed tool such as pliers, which may damage the stem.• Check that the actuator rotates so that the valve seats for close off and also rotates open to achieve full Cv. Use the gear release or the AFcrank to verify. For LF or NF models apply power and control signal ifnecessary.• Verify that CCW (L) rotation of the actuator will open the ball to flow.• Install and tighten the hold down screw not more than 1/2 turn beyondthe point where resistance is felt.Installation1. Inspect shipping package, valve, linkage, and actuator for physical damage. If shipping damage has occurred notify appropriate carrier. Donot install.2.If a replacement, remove 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 drawings on page 2 and 4. Check that inlet and outlet of 2-way valves are correct;check that the “A” and “AB” ports of three-way valves are piped correctly.Flow direction arrows must be correct.5.Blow out all piping and thoroughly clean before valve installation.6.Clean male pipe threads with wire brush and rag. If threads have beendamaged 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 should be applied sparingly after cleaning andmay not be applied to the two lead threads of a screwed pipe, which are innermost inside the valve. Sealing compound is to be placed on male threads only. The purpose is to lubricate the pipes when tightening.8.Valve must be installed with the stem towards the vertical, not below horizontal.9. Start the connection by turning the valve or pipe by hand as far aspossible. Be certain the threads mate by the “feel” of the connection.10. Use wrenches to tighten the valve to the pipe. Do not over tighten or strip the threads. Two wrenches are necessary to avoid damaging the valve. Avoid excessive stresses. Mechanical support must be provided wherereducers have been used and the piping system may have less structuralintegrity than full pipe sizes. Sufficient upstream and downstream piping runs must be provided toensure proper valve capacity and fl ow response. Five diameters in each direction are recommended. Life span of valve stems and O-rings is dependent on maintaining non-damaging conditions. Poor water treatment or fi ltration, corrosion, scale,other particulate can result in damage to trim components. A water treatment specialist should be consulted. Normal thread engagement between male pipe thread and valve bodyshould be observed. Pipe run that is in too far will damage the valve.Warning!Valve should not be used for combustible gas applications. Gas leaks and explosions may result. Do not install in systems, which exceed the ratings of the valve.Subject to change. © Belimo Aircontrols (USA), Inc.Next >
