- Conduit Connection:
- 1/2" male NPT, 1/2" female NPT on WP and WP2.
- Process Connection:
- 1" male NPT.
- Mounting Orientation:
- Actuation/deactuation flow rates are based on horizontal pipe run and are nominal values. Unit cannot be used with vertical down flow.
- Set Point Adjustment:
- Vane is trimmable.
- 4.5 oz (0.13 kg).
- Agency Approvals:
- CE, cURus.
- 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
- 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

- Can the V8 float switch be used with acids due to its material of construction?
- No. The V8 contains a 316SS pin and spring as well as a ceramic 8 magnet that are not compatible.
- What does actuation and de-actuation mean?
- Actuation means that the flow rate has reached a point where the microswitch trips or the contacts of the microswitch change state. De-actuation means that the flow rate has decreased to a point where the microswitch returns to its normal state.
- What material is used as a seal between the process fluid and the electrical portion of the switch?
- The body material; as there is no separate "seal" since the body is machined from solid stock and the switch is magnetically actuated.
- On your Flow Switches, which model has a Form C type contact
- Form C contact is a SPDT snap switch. Many of Dwyer’s flow switches have SPDT snap switches. The V4, V6, V7, FS-2, and V8 are some of them.
