Graco Trabon MSP Zero-Leak Inlet Shut-off Valve User Manual

Trabon® MSP Zero-Leak Inlet Shut-off Valve

DESCRIPTION

The MSP Zero-Leak inlet shut-off valve is designed for use in oil only header lines, for the lubrication of extended systems and/or

systems with varied lube frequencies. Such applications include automotive transfer lines, conveyor lines, ﬂexible machining centers and also complete plant lubrication.

The MSP Zero-Leak inlet shut-off valve can be mounted as the inlet section to any primary (master) divider valve assembly. By using a remote manifold kit, it can be teed off of the header line to a remote primary (master) divider valve assembly.

The MSP Zero-Leak shut-off valve is supplied normally closed to ﬂow. When the coil is energized, the zero-leak valve is opened, allowing oil to ﬂow through. Once the proper amount of oil has been dispensed, the valve is de-energized, shutting off oil ﬂow. The Zero-Leak valve is designed for header-line pressures up to 1500 psi.

FEATURES/BENEFITS

Designed for use with an oil header line system, which is • an economical method of providing lubricant to extensive systems. Reduces plumbing and installation cost.

When used in a header line system, lubrication zones are • easily extended or deleted as changes are made to the lube circuit. This reduces engineering design costs.

Enables individual zone lubrication. Prevents over • lubrication thus saving on lubrication costs.

Facilitates individual zone operation and monitoring. • Identiﬁes a fault in a speciﬁc zone for ease of troubleshooting. Helps lessen machine downtime, which means more production time.

Solenoid can be rotated through1800 to accommodate • any electrical hook up --orientation. Allows for faster installation to reduce costs.

Available with three pin mini-connection as standard•

Available with NPSF pipe, BSPP or SAE, o-ring sealed ports. •

Inlet restrictor/ﬁlter available for use in continuous • pressurized header line systems. This will slow down lube inrush and enable accurate control of the lube systems. Order Part Number 563074 (463-410-204) for NPT pipe inlet.

Coil is molded and sealed, making it impervious to coolant. • Allows mounting of valve in harsh environments.

OPERATION

The MSP Zero-Leak inlet shut-off valve is used in conjunction with an oil header line lube system with each shut-off valve representing a zone of lubrication (See Fig.1). The header line can either be continuously (use restrictor) or intermittently pressurized upon demand. When the particular machine zone requires lubrication, based upon a pre-determined interval, an electrical signal from a Trabon Flexi-Monitor ® or machine PLC will sequentially energize the solenoids attached to the shutoff valves (A1), (A2), and (A3). This will open the valve and allow lubricant from the header line to cycle the divider valve, thus providing lubricant to the points within the zone. Once the zone has received the proper amount of lubrication, determined through monitoring the cycle switch (B) or proximity switch (B) for appropriate number of cycles, the controller will de-energize the solenoid and the valve will shut-off lubricant ﬂow.
