    TESCOM 44-1300 Series is a high pressure, high flow pressure reducing regulator that offers a venting and balanced valve design. The 44-1300 Series provides Cv = 0.8 and 2.0. Dome and air load options are available.

    Applications
    •    Commercial diving – breathing air
    •    Special gas mix regulation hard suit diving
    •    High pressure tube trailer gas reduction
    Features and Benefits
    •    Large piston sensor gives excellent sensitivity
    •    Balanced valve design ensures stable downstream pressure
    •    Large handknob provides fast low-torque pressure settings
    •    Venting is standard
    •    Available with gauge ports
    •    Dome and air loaded models are available (non-venting only)

    1.    For extended temperatures from -40°F to 400°F / -40°C to 204°C, consult TESCOM.
    2.    A secondary pressure drop due to the outlet cross-hole can significantly affect the rated flow capacity. Flow curves should be used for critical sizing applications.
