DeZURIK Switches and Position Transmitters

Design Features:

Design & Construction

DeZURIK can provide mechanical or proximity switches on PowerRac, Compak, Diaphragm, T-Series, G-Series and MG-Series actuators. Position switches can be ordered separately or combined with a position transmitter in one enclosure. They can be mounted directly to DeZURIK valve actuators or to positioners.

The enclosure is epoxy coated, anodized aluminum. The explosion proof, corrosion resistant and water-tight enclosure is available in Nema 1, 3, 4, 4X, 5, 6, 7, 9, 12 & 13 ratings. A screw-on cover allows easy access to adjust switch settings. Settings of less than 1° are easily accomplished with a hex key wrench. As standard, the enclosure is equipped with two conduit connections.

Open and closed position is prominently displayed in a wide-angle viewing area. A prewired and labeled terminal strip enables quick, convenient attachment of field wires.

Mechanical Switches
The two SPDT or four SPDT switches are rated at 10 amps at 125/250 VAC and 0.5 amps at 120 VDC. The top switch is set to indicate the fully closed position and the bottom switch the fully open position.

Proximity Switches
The proximity switch is rated at 0.3 amps at 120 VAC and 0.2 amps at 30 VDC. The top switch indicates the valve is in the closed position and the bottom switch indicates the valve is in the open position.

Position Transmitters
The position transmitter provides a 4-20 mA signal that can be reversed. Operating life is 2,000,000 cycles. Recommended power supply is 24 VDC, 50 mA min. Maximum load: 700 ohms.
