sequence valve application

Sequence valves from Power Team, part of its range of in-line automatic valves, are designed for use in applications when one cylinder in a multi-cylinder application must advance before any other. Objective: To become more knowledgeable with the hydraulic system.A sequence valve is used to cause actions to take place in a system in a definite order, and maintain a predetermined minimum pressure … The application of a Sequencing Valve. that requires the valves to operate over a long life for drain, vent, emergency shutdown and severe isolation applications worldwide. A simple operation for ease of use – the pump is connected to one port and separate cylinders to another two ports (see diagram in PDF). Hydraulic Sequence Valve Application. Actually, the use of the word All reducing valves have an external drain port, and on all applications, without exception, a drain line must be run directly to tank. Typical application for the PSA is a hydraulic brake release of a … Let us consider a hydraulic circuit in which two cylinders are used to execute two separate operations as shown in Figure 6.24. : 1 Use of Pressure Sequence Valve in Clamping Application Work Pieces are to be clampedusing a Pneumatic Cylinder. body, and do not refer to the application of the valve in the system. A common application is to direct a fixed flow rate to a priority function, such as steering, while secondary flow is available to other intermittent functions. There are clamp cylinder and extend cylinder, clamp cylinder will have to clamp the part and extend cylinder will have to extend the part to make contact with cutting tool. Let us see the circuit diagram. Figure 6-15 shows an installation of two sequence valves that control the sequence of operation of three actuating cylinders. The sequence valve depends on an actuator to stop and block flow so that _____ rises to open it. Typical application for the PSI sequence valve is when starting against load where the spring chamber can be vented externally (spring chamber pressure directly adds to the pilot pressure required to shift the valve). A reducing valve drain can usually be combined with the drains from other reducing valves or sequence valves but should never be teed into a main tank return line. 1 is often referred to as a “diverting” application of a three-way valve because, as the valve modulates, a portion of the supply water is diverted around the coil. Ex. Flow divider/combiners are pressure compensated valves. Now, let us assume that cylinder A is required to extend completely before cylinder B extends. It is necessary that the piston advances on actuation of a Hand Push button only after the desired pressure is available in the working pressure supply. For instance, the application described in Fig. Application of sequence valve in operation of machining of a part. The sequence valve pressure is set higher than the first actuator operation pressure. This can be accomplished by placing a sequencing valve just before cylinder B as shown. Superior Performance While some valve manufacturers profess a rising-stem ball valve is suitable, MOGAS believes the CA-1AS quarter-turn ball valve offers superior performance and longevity. (HL5 1-1) ... Pressure-reducing valves can be used in any application where the process requires one or more _____ to operate at pressures lower than the main circuit pressure. A sequence valve is somewhat similar to a relief valve except that, after the set pressure has been reached, the sequence valve diverts the fluid to a second actuator or motor to do work in another part of the system. (HL5 4-5) Once the first actuator has completed its cycle, the sequence valve opens, allowing the second actuator to move.
