Piston valve DPM

for oilin-linefor centralized lubrication systems

Lubricant dispensing sequence The initial piston dispenses lubricant to the outlets corresponding to the final piston. The final piston dispenses lubricant to the outlets corresponding to the central piston or, if more than one, to the outlets corresponding to the closest intermediate piston. The intermediate piston dispenses lubricant to the outlets corresponding to the initial piston. The metering pistons in the DPA progressive dividers do not dispense the pre-established lubricant to the corresponding outlet but based on a set circuit sequence.
