Commercial Pressure Switches

Product Descriptions

The Class 9013 Type F line of pressure switches are UL Listed and CSA Certified as commercial control equipment. The Class 9013 Type G line of pressure switches are UL Listed and CSA Certified as commercial/light industrial control equipment.

Type FHG - PUMPTROL® Compressor Pressure Switch

The Type FHG - PUMPTROL® Compressor Pressure Switch is used to control electrically driven air compressors. It is diaphragm actuated and has contacts that open on rising pressure.

Type FSG, FYG, FRG - PUMPTROL® Water Pump Pressure Switches

The Type FSG, FYG, FRG - PUMPTROL® Water Pump Pressure Switches are used to control electrically driven water pumps and have the following features:

• The Type FSG is the standard water pump switch, suitable for all types of pumps: jets, submersible, reciprocating, etc.
• The Type FYG is designed to meet higher horsepower and pressure requirements.
• The Type FRG is reverse acting: the contacts open on falling pressure.
• All are diaphragm actuated.

Type G - PUMPTROL® Commercial/Light Industrial Pressure Switch

The Type G - PUMPTROL® Commercial/Light Industrial Pressure Switch is used to control electrically driven water pumps and air compressors. It has higher electrical ratings for direct control of motors in pump and compressor applications. The Type G switch is diaphragm actuated and has contacts that open on rising pressure.

Technical Overview

Operating Points (Settings)

Every pressure switch has two operating points: one on rising pressure and one on falling pressure. The operating point on rising pressure is referred to as the TRIP POINT or cut-out for pumps and compressors, and the operating point on falling pressure is referred to as the RESET POINT or cut-in for pumps and compressors. These operating points are called the SETTINGS of the switch.

• TRIP POINT (rising pressure)
• RESET POINT (falling pressure)

Differential

The differential is the difference in pressure between the trip point (cut-out) and the reset point (cut-in). It can be adjustable or nonadjustable (fixed). Example:

Cut-in: 30 psi
Cut-out: 50 psi
Differential: 20 psi (50-30 psi)

Range

The range is the pressure limits within which the operating points (settings) can be adjusted. The range of the Class 9013 pressure switch is referenced to the operating point on rising pressure (trip point). The differential subtracts from the trip point setting.

During the normal operating cycle, system pressure should never exceed the upper limit of the range when using a diaphragm actuated switch. This will greatly reduce the life of the diaphragm.

Maximum Allowable Pressure

Maximum allowable pressure is the pressure to which a switch can be subjected without causing a change in operating characteristics, shift in settings, or damage to the device.

Pressure surges may occur in a system during the start-up of a machine or from valve operation. Surges are not normally detrimental to the life of a switch if the surge is within the maximum allowable pressure rating of the switch. Diaphragm actuated switches should not be subjected to more than 10 surges per day. More frequent surges will greatly reduce the life of the diaphragm.
