1CE20 Series Counterbalance Cartridge Valves, Up To 5000 PSI & 5 GPM

Application	To control moving loads and prevent load runaway, giving load holding and hose failure safety. See Introduction to Counterbalance (Overcenter) Valves at the beginning of this section.
Features	The 1CE20 is a 3 port, externally piloted, screw-in cartridge-type counterbalance (overcenter) valve. Requires a machined A22903 cavity or housing for installation.
Housing	Cavity size A22903, sold separately.
Installation	30 ft-lbs torque cartridge into cavity. Unrestricted mounting position.
Pilot Ratios	3:1 - Best suited for extremely unstable applications such as long booms or flexible frameworks. 4.5:1 - Best suited for applications where load varies and machine structure can induce instability. 8:1 - Best suited for applications where the load remains relatively constant.
Recommended Filtration	ISO level 18/13 or better.
Specifications	5 gpm rated flow. 4000 psi max load induced pressure, 5000 psi max relief pressure. CAUTION: Pressures over 3000 psi require a steel housing. -22° to +194°F operating temperature range. 5 drops per minute max internal leakage. Based on oil temperature of 104°F and 150 SSU.
