"1.12""wc SPST Pressure Switch"
This 1.12""wc SPST pressure switch activates when a minimum pressure of 1.10""wc is reached while at the same time automatically resetting to its original off position when the pressure falls back to or below one (1.00")"WC.
Weil Mclain pressure switch for furnaces. Used on many brands of furnaces with 1.12"wc service piping and have a SPST Pressure Switch with black toggle to install.
The WEIL 511-624-303 SWTH PRES SET AT 1.12 WC Pressure Switch is an air pressure switch that allows a pilot light to be turned on if the air pressure is too low. If the air pressure gets too low the pilot light will automatically turn on, as well as a buzzing sound.
This 3/4" valve is pneumatically controlled and designed for air use. The operating pressure range for this valve is set from 0.7 to 2.5 PSI. Valves are available in brass or stainless steel construction. The DIN setting is shown on the front or top of the trim indicating direction of flow. Weil 511-624-303 SWTH PRES SET AT 1.12 WC Air Pressure Switch 1.22"
SWTH PRES SET AT 1.12 WC. INPUT 120 VAC,. OUTPUT 24 VAC 12 WATTS, PRESS RANGE 7 - 13 PSI , MATERIALS OF CONSTRUCTION: NYLON 202, OPERATING TEMP OF -22 TO 176 DEGREES FAHRENHEIT, OPERATING PRESSURE 0 TO 13 POUNDS PER SQUARE INCH (FPM) @75 DEGREES F T/R.
The Weil Mclain Pressure Switch is used to transfer single stage pump operation. The switch has two terminals and a diaphragm. When the pressure in the system increases above the selected value, the diaphragm moves inward, closing the normally open contacts (SPST) and completing the electrical circuit to operate a control relay or other equipment. When pressure drops below the selected value, the diaphragm moves outward, opening the contacts (SPST) and stopping electrical power flow. Specifications:
A pressure switch for use with water high temperature of 200C, suitable for DC 5V and AC 10A. The maximum pressure is 121bar.
