Sequence valves
Nominal size 4, pmax. 500 bar, with integrated check valve
The sequence valves are used in the clamping hydraulics as a directly controlled sequence valve. The compact design (M20) enables space-saving installation directly in the fixture.
The sequence valve is a poppet valve that operates leakage-free compared to a spool valve. The inlet and outlet pressure are always identical for sequence valves. This makes this type of valve ideal for use in sequence control systems. With single-acting cylinders, only one supply line from the pressure generator is required for operation. The design enables valve combinations that can be flanged together to form a block using a common P-connection and standard parts.
Valve combinations:
Combinations of sequence valves are assembled from an inlet valve (P) and a maximum of four flange-mounted in-line valves. These are supplied with pressure oil through holes. The valve housings are sealed with O-rings. In order to ensure proper function in sequential control systems (parallel connection), there should be a certain minimum pressure difference from valve to valve. This should be as follows for the versions:
ZSV-160... --> 25 bar
ZSV-315... --> 35 bar
ZSV-500... --> 50 bar
