Port Size: The main inlet and outlet ports of the valve are likely to be in the range of 1 - 1.5 inches in diameter. This is a common size range for hydraulic valves used in excavators of the PW160 and PW180 - 7 class, allowing for sufficient fluid flow to power the various hydraulic functions of the excavator.
Pressure Rating: Typically, hydraulic main control valves for these types of excavators are designed to handle pressures in the range of 200 bar (20 MPa) to 350 bar (35 MPa). Given the heavy - duty nature of excavator operations, the 723 - 57 - 17200 and 723 - 58 - 17200 valves are likely to have a maximum pressure rating around 300 bar (30 MPa) to ensure reliable operation under high - pressure conditions.
Flow Capacity: The flow capacity of the valve is an important parameter, and for excavators like the PW160 and PW180 - 7, the main control valve is expected to have a flow capacity in the range of 100 to 200 liters per minute (L/min). This allows for smooth and efficient operation of the hydraulic cylinders and motors that control the excavator's boom, arm, bucket, and other movements.
Valve Type: It is a spool - type control valve, which is a common design in hydraulic systems. Spool valves use a movable spool inside a valve body to control the flow of hydraulic fluid. This design offers precise control over the direction and amount of fluid flow, enabling the operator to accurately position and control the excavator's hydraulic components.
Operating Temperature Range: The valve is designed to operate in a wide temperature range, typically from -20°C to +80°C. This is necessary to ensure reliable performance in various environmental conditions, from cold winter days to hot summer operations.
