Measuring Valve
GeneralThe DPD and DPS series of measuring valves are used in “dual line” lubrication systems to deliver a precise amount of lubricant to a varying number of lubrication points. These valves are precision honed, repairable, and constructed to operate in harsh industrial environments.
These valves have been designed to fit Farval® Brand mount-ing with the exception of our DPD20 series (which have been made larger to accommodate fitting installation).

•Internally cross-ported (no need for special kits)•Proprietary packing gland that yields proven longer life.•Precisely manufactured allowing for replacement parts for emergency repair. •Solid copper washers for better seals•Tapered pipe threads. Any standard N.P.T. pipe thread will work in our valves--leak free!

The DPD series of measuring valves are “dual discharge” metering de-vices that have been designed to deliver precise amounts of lubricant in dual line lubrication systems. Because it is “dual discharge” it will discharge a shot of lubricant out of either the top or bottom discharge port for each piston stroke. Therefore each piston can supply lubricant to two points.

DPS 53
The DPS series of measuring valves are “single discharge” metering devices that have been designed to deliver precise amounts of lubricant in dual line lubrication systems. Because it is “single discharge” it will discharge a shot of lubricant out of one discharge port for each piston stroke. Though each piston only supplies lube to one point, it delivers twice the amount per stroke com-pared to the DPD series.

It is contructed of solid brass and features a ridged top that enable easy removal.To install, first remove the existing vinyl indicator cover. Place the brass indicator cover over the packing gland and press down until the brass indicator cover reaches the hex on the bottom of the packing gland.

Dyna-Power Engineers • 15330 Greenwood Rd. • South Holland, IL 60473 • ph:708-333-9300 • fax: 708-333-7092 CROSS-PORTING
Cross-Porting
To convert a DPD valve from dual to single discharge, perform the following for each discharge port that you would like cross-ported.
1. Turn the valve upside down and locate the phillips screw visible in the bottom of the discharge port. See Fig. 11-1.
2. Using an appropriately sized screwdriver, remove the screw.
3. The copper washer under the screw must also be removed. Turn the valve upright again, and gently tap the valve on a firm surface until it falls out. De greaser and/or compressed air will help remove the washer. It is very important that the washer be removed. Leaving the washer in may disrupt lubricant flow.
4. Install pipe plug in either discharge port. For DPD 30 and DPD 50 series of valves, use a 1/4” n.p.t. plug. For DPD 20 series, use a 1/8” n.p.t. plug. See Fig. 11-2.
To convert a DPD valve from single discharge back to dual discharge, perform the following for each discharge port that has been cross-ported:
1. Simply place the copper washer on the cross-port screw and using an appropriately sized screwdriver, install the screw through the bottom of the discharge port.
2. Remove the pipe plug from the discharge port.

Fig. 11-2
Cross-Porting Instructions
In cases where more lubricant is required for a particular lube point(s), or a discharge port is unecessary, cross-porting the valve is required. By simply removing a screw and a washer, the dual discharge valve can be converted into a single discharge valve--thus allowing for the proper plugging of a discharge port. Note: when a valve section is cross-ported, the amount of lubricant that is discharged is doubled.
