131542 - LOGIC ELEMENT - CP701-1-B-0-100 - DANFOSS
Logic Element, Normally Closed, Spool Type, Pilot to Close
350 bar [5000 psi] • 150 l/min [40 US gpm]
DESCRIPTION AND OPERATION
This is a 3-ported, normally closed, pilot to close spool type logic element. By opening port 3 to tank, flow can pass from port 1 to port 2. Flow is blocked from port 1 to port 2 unless the pressure is high enough in port 1 to overcome the spring set pressure. Applying pressure to port 3 will increase the pressure required in port 1 to open the valve by a factor of 1 to 1. This valve is ideal for use as a pressure compensator, bypass valve, or a pilot to close valve in regenerative circuits

Description: CP300-4-B-0-0-190
Pressure Compensator, Restrictive Type 210 bar [3000 psi]• 40 I/min [11 US gpm] 
This is a 3-ported spool valve, where port 3 is connected to port 2 and port 1 is the pilot port. The spring chamber is connected to port 3 through an orifice. When port 3 is connected to the outlet of a control orifice and port 1 is connected upstream of the orifice, the valve functions as a restrictive pressure compensator. When the pressure drop across the orifice is equal to the spring set pressure, the spool restricts flow from port 3 to port 2 and compensates for any change in pressure difference across the valve.
