Frequently asked questions
Common questions about POWERMATE from 3G Electric.
What pressure ranges are available for POWERMATE pressure switches?
POWERMATE pressure switches are offered in two common ranges: 100 to 130 psi (model 034-0197RP) and 145 to 175 psi (model 034-0199RP). Both are four-port designs, allowing connection to pressure gauges, relief valves, or other control components. The switches are typically used to control compressor motor cut-in and cut-out pressures.
Are POWERMATE pressure relief valves ASME certified?
Yes, certain POWERMATE pressure relief valves, such as models 136-0005RP (150 psi) and 136-0077RP (175 psi), are ASME certified. These valves are designed to relieve excess pressure in compressor tanks and piping systems, ensuring compliance with safety codes. Always verify the pressure rating matches your system requirements.
What thread sizes do POWERMATE tank drain valves use?
POWERMATE tank drain valves, including the wing-style (072-0001RP) and quarter-turn style (072-0020RP), use a 1/4" NPT thread. This is a standard size for compressor tank drains. The wing-style valve requires manual turning, while the quarter-turn valve allows faster operation. Both are suitable for periodic moisture removal.
Can POWERMATE unloader valves be used on any compressor?
POWERMATE unloader valves, such as model 070-0061RP, are designed for compressors operating in the 125–155 psi range. They relieve head pressure during compressor start-up to reduce motor load. Compatibility depends on the compressor's pressure range and port configuration. Cross-reference the manufacturer part number (070-0061RP) with your compressor's service manual.
What is the purpose of a POWERMATE vibration isolator?
The POWERMATE vibration isolator (model 094-0190RP, measuring 2.25" x 1") is installed between the compressor pump and its mounting base. It absorbs mechanical vibrations generated during operation, reducing noise and preventing loosening of fasteners. This component is a wear item and should be inspected during routine maintenance.
