Trabon® MSP Modular Zero-Leak Valve & MSP Modular Filter

MSP MODULAR ZERO-LEAK VALVE SECTION

DESCRIPTION

The MSP Zero-Leak Valve Section functions as an inlet shut-off valve for use in oil only zoned header line systems up to 3,000 psi. Typical applications include automotive transfer lines, conveyor lines, ﬂexible machining centers and also complete plant lubrication systems.

Its three-piece design utilizes a base block, a valve block containing the two-way valve, and solenoid coil which is energized by the lube system controller. The base plate is dedicated for use with the new inlet Zero-Leak valve and modular ﬁlter only, and is compatible with the MSP stackable sub-plate section. It is installed directly in the divider valve assembly with the metering valve sections and secured by tie rods. The cartridge valve block is bolted to the base plate. The Zero-Leak Valve Section is normally installed below the MSP Modular 25 micron Filter Section Part Number 563480 (527-005-760) described below.

The MSP Zero-Leak Valve Section is supplied Normally Closed to ﬂow. The valve is bubble tight at normal header line pressures. When the solenoid coil is energized by the system controller during a lube cycle, the valve opens, allowing oil to ﬂow through the ﬁlter and downstream divider valve sections and on to the lube points.

Standard end section for a Zero-Leak valve equipped •

MSP feeder assembly is an SPP "bottom-feed" section with special leak-proof hydraulic ﬁtting. The manual feed capability facilitates time-efﬁcient maintenance actions by not requiring entire lubrication system to be operated when one zone and its feeders' operation is being evaluated. System-ﬁll and air purging procedures can also be more efﬁciently accomplished by using the bottom feed sections lube ﬁtting.

FEATURES/BENEFITS

Zoned lubrication systems enable customized, exact control •

for each individual zone, prevent over lubrication, reduce plumbing and installation costs, and allow a smaller pump and reservoir to serve an extended system.

With a zoned header line system, lubrication zones are easily •

added or removed. Zones may be individually controlled and monitored to verify that the system's performance fulﬁlls the system design requirements.

The base plate/valve block design allows the removal and •

replacement of the shut-off valve module without disturbing line connections and introducing air or other contamination into the system.

OPERATION

The MSP Zero-Leak Valve Section starts and stops the ﬂow of oil to other sections of the divider valve in which it is installed (and in any secondary divider valve to which it may be connected). The solenoid coil surrounds a ferromagnetic plunger which is connected to a needle valve. The needle valve is held normally closed against its seat by header line pressure.

When the lube cycle program calls for lubrication of the points supplied by the divider valve stack, an electrical signal from the system controller (Trabon Multi-Purpose Controller or machine PLC) energizes the coil which lifts the needle off its seat. This allows oil to ﬂow through the downstream metering sections to the connected lube points. Once the zone or zone section has received the proper amount of oil (determined by monitoring divider valve cycles), the solenoid is de-energized, allowing the needle valve to return to its seat and shutting off ﬂow to the entire divider valve assembly.
