Product Detail
Function and configuration
2-way cartridge valves are designed as inserts for compact manifold control blocks. The installation hole dimension of the control block fitting the main valve component with ports A and B is in accord with ISO 7368 and sealed with a cover. In most cases, the cover also acts as a connection between the control side of the main component and the pilot valves. By controlling the main valve with suitable pilot valves, the main component can assume pressure, directional or throttling functions, or their combination.
Particularly economic designs can be achieved by matching the valve sizes to the individual actuator. When the element on the main valve is able to assume more than one function, a particularly economic design can be achieved.
Directional function:
2-way cartridge valves basically comprise of control cover (1) and cartridge element (2). The control cover contains the control holes, and optional stroke limiter depending on the function, a hydraulically controlled directional poppet valve or a shuttle valve. In addition, directional spool valves or directional poppet valves may be mounted onto the control cover. The cartridge element basically comprises of a sleeve (3), an adjustment ring (4) (only up to NG32), valve poppet (5), optionally with damping nose (6), or without damping nose (7), and return spring (8).
Function:
Operation of 2-way cartridge valves depends on pressure. Hence for operation, there are three important pressure-bearing areas: A1, A2, A3. The area A1 on valve seat is taken as 100%. The annular area A2 is 7% or 50% of area A1 depending on the model. The area ratio A1:A2 is, therefore either 14.3:1 or 2:1. Area A3 is equal to sum of areas A1+A2. Due to the different area ratios A1:A2 and consequently the different annulus area (A2), area A3 may be either 107% or 150% of the 100% area at seat A1.
Basic application :
Areas A1 and A2 operate to open the valve. Area A3 and the spring operates to close the valve. The effective direction of the resultant force (of opening and closing forces) determines the switched position of the 2-way cartridge valve.
2-way cartridge valves may have flow passed from A to B or from B to A. When pilot oil acting on area A3 is from port B or supply from an external pilot oil, port A is closed, and leakage-free.
