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.

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.

A sequence valve is called a non-passing pressure control valve which allows one operation to occur before another based on pressure. In order 

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.

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

A sequence valve is a pressure valve designed to open when its set pressure is reached, providing a path of flow alternate and sequential to the primary circuit. In some ways, a

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.

A pressure-reducing valve is a self-operating valve that is used to reduce any excess pressure in a system. Sometimes this valve is also known as pressure reducing regulator. The basic function of pressure-reducing valves is to reduce higher pressure into lower. They are commonly used in water, steam, and oil & gas industries.
