We will study here the working principle and internal construction of Pressure sequence valve. Sequence valve is also one type of pressure control valve which is used in order to operate two actuators i.e. cylinders in a sequence. Let we have two hydraulic cylinders in a hydraulic circuit.

A sequence valve is a valve that controls the order in which fluids or gases flow through pipes, tubes, or other conduits. An unloading valve is a type of check valve which relieves backpressure on the fluid being pumped by allowing fluid to flow in the opposite direction.

The PSV8-10 screw-in cartridge pressure sequence valve is ideal for diverting oil to a second circuit at the predetermined pressure, or as a relief when 

Sequence valve set at 150 psi (10 bar) Figure 1. A Sequence Valve can be used to maintain a minimum pilot pres-sure for directional valve actuation in lieu of a back-pressure check valve. When system pressure rises above the sequence valve setting, parasitic pressure drop, based on the valve's pressure setting, disappears.

Sequence valve is used to feed 2 cylinders in sequence: it provides flow to the secondary circuit when a primary circuit function has been complted re.

Pneumatic sequence valves typically are 5-way directional control valves with adjustable springs to set their shifting pressure. They are used to start a second operation after the preceding one finishes. Some older machines have one solenoid valve to start the cycle and several sequence valves to extend and retract all other actuators.

A sequence valve is widely used in a hydraulic system these valves are pressure control valves. The sequence valves are similar to a pressure relief valve and these valves are used where a set of operations are to be controlled in a pressure-related sequence. The major function of a sequence valve is to divert the flow in a predetermined sequence.

Hydraulic sequence valve will normally be in closed position and it will only come in line once pressure increases and reaches the setting point of sequence valve. Hydraulic sequence valve will have one pilot line to sense the inlet pressure. Hydraulic sequence valve will have one check valve to allow free flow in reverse direction.

What is a pressure sequence valve? A sequence valve is a pressure-operated, normally closed, poppet or spool valve that opens at an adjustable set pressure. Some designs use a spring acting directly on the spool or poppet, others are pilot-operated. A sequence valve always has an external drain port to keep from trapping leakage oil.

The compound pressure relief valve consists of a small pilot operated relief valve with poppet arrangement and a main relief valve (Figure 1). It also consists of two ports, of which is one is pressure port, and the other is tank port. Pressure and tank ports are connected to the pressure line from the pump and the tank respectively.

A sequence valve is a pressure control valve that is used to force two actuators to be operated in sequence. Relief valve, pressure reducing valve, and sequence valve. It is a combination of adjustable. They are commonly used in water, steam, and oil & gas industries. Hydraulic relief and sequence valves. Source: www.wandfluh.at

These valves are used to feed two cylinders in sequence: it provides flow to the secondary circuit when a primary circuit function has been completed.

Sequence valve use mostly spool elements, with some poppets, which sense pressure over a set area to move the spool against an adjustable spring. When the pressure reaches a pre-set value it opens a second port to divert the flow. Sequence valves are available as: Direct or Indirect Operation Direct operation is when the pressure is applied
