  • ULTIMHEAT : Piston flow switches, reed switch contact, inlet and outlet 3/4” BSPP male. Type R36

    Piston flow switches, reed switch contact, inlet and outlet 3/4” BSPP male, Type: R36
    Pressure and size Flow sensing:
    Magnetic piston
    Mounting:
    3/4” male inlet and outlet
    Contact:
    Reed switch, close on flow rise
    Electrical rating Mounting position Type
    PN10 R36
    DN20

    Cable connection model
    1: 3/4” BSPP Water inlet
    2: Flow detection piston
    3: 3/4” BSPPWater outlet
    4: Over-pressure valve

    Main applications:
    Product developed for electrical or gas instantaneous water heaters. 3/4 “ BSPP male water inlet and outlet. Mandatory vertical mounting, with water inlet from the bottom. Built-in over-pressure valve
    Functional principle: Magnetic piston mounted in line with the flow and activating a reed switch through the wall. The return of the piston is by made by gravity. No seal or liquid can pass between the piping system and the electrical contact. Suitable for potable water. Must not be used for water containing magnetic particles or high viscosity liquids, which block the movement of the piston.
    Adjustment: Can be factory set by adjusting the piston diameter and piston weight
    Body material: PPO compatible with drinking water.
    Piston: PPO
    Electrical rating: Max 1A, Max 70W, Max 250V, resistive load. Use on inductive circuits reduces electrical rating. We recommend to protect the reed switch with contact protection device when used in inductive loads
    Electric contact type: Normally open, closes by flow rise
    Liquids compatibility: For use with clean water and liquids without magnetic particles and without chemical incompatibility with PPO Nominal pressure at 20°C: 1MPa (PN10)
    Flow detection set point factory setting limits:
    Close by flow rise: 2,4 to 8 L/min
    Open by flow decrease: About 0.4 to 0.5L/min lower than close value
    Nominal diameter: DN20
    Mandatory mounting position: on vertical pipes, upstream flow
    Water pipe connection: Water inlet and outlet: 3/4” BSPP male fitting (Needs gasket). Recommended torque: 7N.m
    Liquids temperature range: 5 to 80°C
    Ambient temperature range: 5 to 50°C
    Overpressure valve calibration value: 1.5 MPa +0.5, -0
    Ingress protection: IP65
    Electrical connection: 2 x AWG24 wires (0.2mm²), PVC insulation, T80°, standard length 300 mm.
    Options (MOQ apply):
    - Wires with connector or terminals,
    - Other wire lengths,
    - Other calibration values
    - Upside water inlet,(by adding an internal stainless steel piston spring)
