Various considerations are vital when picking a Manifold for specific applications. The material and finish will determine how much pressure the Manifold can handle. Durability is also dependent on the material type. Other fundamentals to look at include; electrical voltage and connection, the number of valves, temperatures and environmental conditions, and duty cycle. You also have to know what the fluid type is, the seal material, port sizes, flow conditions, and mounting. Manifolds are widely used in sectors such as oil & gas, chemicals, wastewater, power, and so on. They help measure static, variable, gauge, and differential pressures. There are a variety of manifold valves you can choose from as per your requirement.
Manifold Blocks comprise interconnections of hydraulic valves. The way these connect to one another dictates the control options of a manifold. These valves work to regulate the flow of oil in the circuit and then direct it to a hose system connected to a work device. It is how the Manifold controls distribution. The consolidation of varied parts in a metal chunk comes with its advantages. For one, the layout it creates is logical and without clutter. Having all the components together means that fittings are less. Parts also occupy minimal space this way. There is also the benefit of reduced leak points, less assembly time, and pressure drop.
The manifold is a combination of valves in a single body. Each valve will have separate openings ad controls.
The manifolds commonly use the ball, bleed, needle, and vent valves.
- 3 Valve :
The 3 valve manifolds consist of 3 valves with two block valves and one equalizing valve. There is an extra “bleed” valve, used to vent trapped fluid pressure to the atmosphere.
- 5 Valve manifold:
It consists of 5 valves, 2 block valve, 2 equalizing valves and one bleeding valve. Bleed valve vent out trapped pressure through a tube to some remote location. Equalizing valves never be open while both block valves are open.
