Pressure Limit: Brass lower body with no tee models 1000 psig (69 bar), 303 SS lower body with no tee models 2000 psig (138 bar). Brass tee models 250 psi (17.2 bar), iron tee models 1000 psi (69 bar), forged and stainless steel tee models 2000 psi (138 bar), low flow models 1450 psi (100 bar).
Enclosure Rating: Weatherproof and Explosion-proof. Listed with UL and CSA for Class I, Groups A, B, C and D; Class II, Groups E, F, and G. (Group A on stainless steel body models only). ATEX 0344 II 2 G EEx d IIC T6 Process Temp≤75°C, EC-Type Certificate No.: KEMA 04ATEX2128.
Switch Type: SPDT snap switch standard, DPDT snap switch optional.
Electrical Rating: UL models: 5A @ 125/250 VAC. CSA and ATEX models: 5A @ 125/250 VAC; 5A res., 3A ind. @ 30 VDC. MV option: .1A @ 125 VAC. MT option: 5A @125/250 VAC. [MT option not UL, CSA or ATEX].
Electrical Connections: UL models: 18 AWG, 18" (460 mm) long. CSA models: terminal block.
Upper Body: Brass or 303 stainless steel.
Conduit Connections: 3/4" male NPT standard, 3/4" female NPT on junction box models.
Process Connection: 1/2" male NPT on models without a tee.
Mounting Orientation: Switch can be installed in any position but the actuation/deactuation flow rates in the charts are based on horizontal pipe runs and are nominal values.
Set Point Adjustment: Standard V6 models none. Without tee models vane is trimmable. Low flow models are field adjustable in the range shown. See set point charts on opposite page.
Weight: 2 to 6 lb (.9 to 2.7 kg) depending on construction.
Options not Shown: Custom calibration, bushings, PVC tee, reinforced vane.
Agency Approvals: UL, CSA, CE and ATEX.

Pressure drop (head loss) is a function of both set point and flow rate. Typically, pressure drop at actuation flow rate listed will be 5-10 psid (.34-.69 bar). Pressure drops at other flow rates will vary in proportion to the (change in flow).
