V8 Flotect Vane Operated Flow Switch, Certification : YAS

v8 flotect vane operated flow switch

the series v8 flotect® vane operated flow switches is ideal for protecting unattended equipment from damage or loss of production.

features:

ul recognized as an industrial motor controller per ul standard 508, suitable for mounting in a protected environment

magnetically actuated switching design gives superior performance with free-swinging vane which attracts a magnet within the switch body, actuating a snap switch with no bellows, springs, or seals to fail

leak proof body and vane constructed of tough durable polyphenylene sulfide which has excellent chemical resistance

a full size trimmable vane is provided with molded-in graduations

specification:

service : compatible gases or liquids.

wetted materials : vane and body: polyphenylene sulfide (pps); pin and spring: 316 ss on inconel®; magnet: ceramic 8.

enclosure rating : general purpose; wp/wp2 option is weatherproof.

switch type : spdt snap switch; mv option: spdt gold contact snap switch.

electrical rating : 5 a @ 125/250 vac, 5 a resistive, 3 a inductive @ 30 vdc. Mv option: 1 a @ 125 vac, 1 a resistive, 0.5 a inductive @ 30 vdc.

mounting orientation : actuation/deactuation flow rates are based on horizontal pipe run and are nominal values. Unit cannot be used with vertical down flow.

applications:

boiler flow proving

hot water heaters

chillers

cooling lines

machinery

liquid transfer systems

 options:

gold plated contacts, for dry circuits. Rated 1a @ 125 vac; 1a resistive, 0.5a inductive @ 30 vdc. To order add suffix -mv. Example: v8-mv.

inconel® alloy option. Inconel® alloy replaces standard 316 ss wetted parts. Wetted parts are inconel® alloy, ceramic 8, and polyphenylene sulfide. To order add suffix -inc. Example: v8-inc.

weatherproof enclosure (not ul approved). Optional housing provides weatherproof protection for electrical wiring. To order add suffix -wp (phenylpolioxide) or -wp2 (aluminum). Example: v8-wp or v8-wp2

 installation:

the model v8 flow switch is intended for use in clean, compatible process media free from scale, debris and other foreign matter which might collect on the vane an impede its movement. Buildup from such materials will prevent proper operation.

carefully unpack the switch being certain to remove any packing material which might have become lodged between the switch housing and the vane assembly. Note the pipe size indicators molded into the vane. By trimming at the mark corresponding to the pipe size being used, approximate actuation/deactuation flows will be as shown in the charts at right. These values apply to installations with a thred-o-let, branch connection or plastic fitting. If using standard 125-250 lb. Bronze, iron or steel fittings, trim the vane 0.125 ¿¿ above the mark. Due to variations in fittings and amount of thread engagement, vane must be checked for proper operation.

the flow switch must be properly indexed during installation. The arrow on the side must point in the direction of flow.

use teflon® thread tape or other suitable pipe joint compound to seal the 1 ¿¿ npt mounting connection. Avoid excess sealant which could interfere with vane movement and prevent proper operation. Do not exceed 50 ft/lbs (40 n/m) torque on the switch housing. Damage can result.

wire in accordance with local electrical codes. Lead wire colors are as follows: black - common, red - normally open, blue - normally closed. Normal is the contact condition with no flow in the system. Closed contacts open and open contacts close when increasing flow reaches the actuation point.
