P3A-250-4V
Pumps with 4 way valves are for use with double-acting cylinders. This valve allows the pump to advance or retract a double-acting cylinder at full pump pressure.
A 4-way valve can be placed on any of the P, PH and CP series pumps. To order a pump with a 4-way valve, simply add “-4V” after the pump model number (Example P2A-160-4V)
Features:
- Same features as each Model without this 4-way valve
Typical Applications:
- Industrial transfer of liquid
- Operated presses, valves, doors, safety locks and various other devices
Design Details:
- pumps with these valves do not have release valves because the 4-way valve is used to release pressure
- 4-way valves only used on pumps to 10,000 PSI
- Limited Warranty
All Star pumps are covered by a limited warranty on materials and workmanship for one year from the date of manufacture. Star will repair or replace at its option any pump in which Star finds manufacturing defects. In order to get warranty service a pump must be returned to the Star plant freight prepaid with a written explanation of the problem.
Technical Data
Light hydraulic oil is recommended for use with Star pumps. Oils with SUS viscosity of 75 to 150 at 100 degrees Fahrenheit will give satisfactory performance (ISO grade 15, 22, or 32). In an emergency situation when the above oils are not available, use 5 W or 10 W motor oil or automatic transmission fluid.
All exposed surfaces of standard Star pumps are painted with one coat of industrial quality paint. Pumps painted with special colors with two coat finishes, or with prime coat only, and pumps with special plated or polished parts, are also available.
