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. Once the first actuator has completed its cycle, the sequence valve opens, allowing the second actuator to move. 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. (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. body, and do not refer to the application of the valve in the system. Actually, the use of the word Let us see the circuit diagram. 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. This can be accomplished by placing a sequencing valve just before cylinder B as shown. Ex. : 1 Use of Pressure Sequence Valve in Clamping Application Work Pieces are to be clampedusing a Pneumatic Cylinder. The sequence valve pressure is set higher than the first actuator operation pressure. All reducing valves have an external drain port, and on all applications, without exception, a drain line must be run directly to tank. that requires the valves to operate over a long life for drain, vent, emergency shutdown and severe isolation applications worldwide. 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. The sequence valve depends on an actuator to stop and block flow so that _____ rises to open it. (HL5 4-5) Flow divider/combiners are pressure compensated valves. Let us consider a hydraulic circuit in which two cylinders are used to execute two separate operations as shown in Figure 6.24. Figure 6-15 shows an installation of two sequence valves that control the sequence of operation of three actuating cylinders. Hydraulic Sequence Valve Application. 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). For instance, the application described in Fig. 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. 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. Application of sequence valve in operation of machining of a part. Now, let us assume that cylinder A is required to extend completely before cylinder B extends. 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. 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. 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).
