More Information
Description | HAWE ("hah'-vay") Check valves are a type of non-return valve. They block the oil flow in one direction and open in the opposite direction. In the closed state they have zero leakage. Check valves type CRK and CRB enable free flow in one direction and block flow in opposite direction. Type CRK blocks in direction of B→A, type CRB in direction of A→B. For system pressure up to 500 bar and max. flow from 30, 50, and 80 lpm (depending on size). Their field of application are all standard control purposes within hydraulic circuits where directional valves are operated more or less regularly. These check valves must not be utilized in circuits with a high frequent load changes. In principle all these valves are to be screwed into simply shaped tapped holes of a manifold body. The sealing of the inlet to the outlet takes place at the contact area between the facial sealing edge of the screwed-in end of the valve body and the stepped shoulder of the core diameter the location thread. Any standard steel drill (point angle 118°) automatically forms this stepped shoulder when the core diameter is drilled. Therefore reaming of the hole and bevels to help the seals slip in are not necessary. The sealing of the attached valve and its fixing at the manifold body are via a sealing nut featuring a special thread seal and an O-ring. |
