Overview
The document discusses the Series 20LP and 20LPC work sections designed for use with pressure-flow compensated pumps, known as load sense pumps. These valves are parallel circuit, closed center designs, meaning flow does not pass through the valve when the spools are centered.
Specifications
The load sense signal line must connect to the load sense port on both the pump and the 20LE outlet section of the valve. The pressure-flow compensator maintains output pressure equal to the pressure at the load sense port plus the load sense differential pressure, typically between 150 and 350 psi.
Benefits
Load sense systems offer improved metering of flow to work ports, with pressure limited to a low and constant differential pressure, enhancing the effectiveness of metering notches in the spool. This results in better resolution of spool travel versus flow out of the work port, regardless of the pressure required at the work port.
Design Features
The Series 20LPC valve includes a pressure compensator upstream of the metering notches on the spool, ensuring constant work port flow regardless of changing load pressure requirements. The valve is suitable for applications requiring precise flow metering under varying conditions.
Flow Management
The 20LPC sections have flow-rated spools determining maximum flow from individual work sections. Parallel circuitry allows multiple sections to be used simultaneously to meter flow. If the total flow demand exceeds the pump's output, flow division occurs based on the section with the lowest pressure demand.
Solenoid Operation
The Series 20 solenoid operated work sections allow remote electrical on-off control. These sections contain two 3-way, 2-position screw-in style cartridge valves, providing a robust platform for higher tank pressures in mobile applications.
Application Notes
The document provides detailed application notes for Series 20 load sense inlets, including compensator settings and requirements for solenoid operators. It also discusses joystick handles for Series 20 stack valves, allowing operation of two adjacent sections with one handle.
Test Data

Overview
The document provides technical specifications and operational guidelines for Prince Manufacturing Corporation's Series 20 proportional work sections and assemblies. It details the electrical and hydraulic requirements for optimal performance, including current control, pilot pressure, and valve configurations.
Specifications
The coils require a maximum current of 1300 mA at 12 volts, with a dither frequency of 100 Hz and amplitude of 50-100 mA to reduce hysteresis. Adjustable current settings on the controller are recommended to minimize dead band and maximize control resolution.
Procedures
Pilot pressure of approximately 325 psi is necessary to shift the spools in proportional sections. This pressure can be supplied by a compensator inlet or a load sense pump, depending on the system configuration.
Valve Families

Overview
The document provides detailed technical specifications and operational guidelines for solenoid-operated valves manufactured by Prince Manufacturing Corporation. It covers various aspects including pressure build-up valves, solenoid coil specifications, and proportional work sections.
SpecificationsThe document outlines the specifications for solenoid coils used in different series of work sections. It includes details on coil part numbers, duty ratings, ingress protection ratings, wattage, and amperage draw for both 12V and 24V DC, as well as 120V AC coils.
