The throttle valve type CQ and the restrictor check valve type CQR and CQV are, as slotted throttles, insensitive to micro contamination.The restrictor check valve type CQR and CQV combines the function of a flow valve with a check valve. It regulates in one flow direction and permits free flow in the other direction. The double spindle sealing enables leakage-free adjustment, even under pressure. The valve type CQ, CQR and CQV can be screwed-in and can be integrated into control blocks. The necessary mounting holes are straightforward to make. Features and benefits: Leak-free adjustment under pressure Operating pressure up to 700 bar Intended applications: Speed regulation in hydraulic lifting devices
