PAG Valves

The distributors type PAG are used as lubricant manifolds in dual-line central systems. Due to their sturdy construction and long service life, they are predominantly applied upon servicing and extending already existing systems with “PAG distributors“. The task of the distributors PAG consists in proportioning metered quantities of lubricant to the lubrication points.

The distributors are conceived in building-block design. One control and metering piston each is allocated to every lubricating point (4 maximum). The housing block also accommodates the connections for main lines and lubricating points and has fastening holes. Actuation is effected by alternate pressurization of main lines I and II. Complete metering of all metering points of valve is finished after pressurizing main lines I and II.

FUNCTION

Pressure pulse in main line I

If main line I (HL I) is being pressurized, the lubricant will move the control piston towards closure end plug. The lubricant is then led through channel into chamber pressing the metering piston towards closure end plug (4). Lubricant provided in chamber is delivered through channels and to the connection of lubricating point.

Pressure pulse in main line II

If main line II (HL II) is being pressurized, the lubricant will move the control piston towards closure end plug. The lubricant is then led through channel into chamber pressing the metering piston against the stop. Lubricant provided in chamber is delivered through channels and to the connection of lubricating point.

A piston rod is fastened for optical control of functionality to the metering piston signaling the piston motion of control unit due to alternate moving-in and moving-out motions. The optical control unit included in standard outfit simultaneously serves for infinite variation of metered quantity via threaded pins. Thus, the stroke of metering piston is restricted. Upon dispatch of metering valves, the metered quantity is set to maximum. Fastening of metering valves is ensured via welded plates.
