• Dwyer Flow Switch

    Model no. V4-SS-2-U-AT

    Vane-Operated Flow Switch: Field Adjustable – Dependable Protection Against Flow Variation or Stopping in Pipelines for Fluids, Gases and Flowing Solids.

    Features

    • Leak proof body machined from bar stock
    • Weatherproof, designed to meet NEMA 4
    • Explosion-proof
    • Installs directly and easily into pipeline with a threaded branch connection, tee, or flange
    • Can be used in pipes 1-1/2″ and up
    • Electrical assembly can be easily replaced without removing the unit from installation so that the process does not have to be shut down
    • High pressure rating of 1000 psig (69 bar) with the brass body and 2000 psig (138 bar) with the 316 SS body
    • Unique magnetically actuated switching design gives superior performance
    • There are no bellows, springs, or seals to fail
    • Instead, a free-swinging vane attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm

    Applications

    • Protects pumps, motors and other equipment against low or no flow
    • Controls sequential operation of pumps
    • Automatically starts auxiliary pumps and engines
    • Stops liquid cooled engines, machines and processing when coolant flow is interrupted
    • Shuts down burner when air flow through heating coil fails
    • Controls dampers according to flow
  • Quick opening closure, 12″

    Features

    • The closures are available to suit a wide variety of pressure vessel sizes and pressures, from 6” up to 120” diameter and any pressures from class 150 # up to class 2500 #.
    • The closures are designed to meet requirements of ASME VIII Div.1. Furthermore, alternative pressure vessel design codes, such as ASME VIII Div.2, PD5500 and EN13445 can also be accommodated.
    • The locking mechanism incorporates a hand operated pressure warning screw and a Safety locking device and Stopper, which prevents the door being unlocked until there is no residual pressure inside the vessel.
    • The closure hub and door are manufactured from materials that fully comply with the requirements of NACE MR 75-01 / ISO 15156 Latest Edition, HIC and SSC test resistance. – The stress and strain analysis has been successfully performed by finite element (Ansys software) and NPI calculation.
