what is a pressure sequence valve

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 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

Apr 07,  · Pressure-control valves are found in practically every pneumatic and hydraulic system. They help in a variety of functions, from keeping system pressures below a desired limit to maintaining a set pressure level in part of a circuit. Different types of pressure control valves include relief, reducing, sequence, counterbalance, safety, and

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.

A sequence valve is used to ascertain that a certain pressure level is attained in one branch of the circuit before a second branch is activated. A sequence control valve is used to

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.
