Sequence Valve

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

Special features:

  • Space-saving installation options (M20)
  • Quick mounting due to flange
  • Precisely adjustable
  • Ideal for pressure sequencing
  • Operation with one supply line possible
  • Valve combination parallel connection
  • Valve combination Series connection
  • Tight, due to integrated non-return valve
