'pressurereducing valves'

Counterbalance valves are used in hydraulic systems working with an overriding (run-away) or suspended load. They are designed to create back pressure at the return line of the actuator to prevent losing control over the load.

FAILED

Monoblock: Have many outstanding features including high performance, high efficiency, small volume, mass flow, and leak proof. In addition, the compact direction control valves have fixed and big pull rods to control direction, providing various ports and circuit valves. Sectional: Offers multi-function control valve method to solve hydraulic circuit system requirement. The compact construction design is one of strong features for sectional directional control valves include other features, such as low pressure drop high efficiency.

FAILED

Poppet valves are used in hydraulic systems. They are commonly controlled through solenoids and can be set to be either normally-closed or normally-open in their de-energized states. They are also used as check valves to provide one-way flow and as relief valves to guard against over pressure.

FAILED

Check valves are the simplest form of hydraulic devices in that they permit free oil flow in one direction and block oil flow in the opposite direction. Check valves may also be used as a directional or pressure control in a hydraulic system.

FAILED

Directional control valves are used to control the direction and movement of hydraulic fluid through a system. They are often referred to as switching valves and come in three main categories: hydraulic check valves, directional spool valves and poppet valves that make up the different types of control valves.

FAILED

Unloading valves are used in hydraulic circuits, these valves would stop or remove the flow of the pump back to the tank when the machine is not operating. So by this reduction of heat and energy saving can be achieved because the prime mover load is reduce

FAILED

sequence valves can be used to sense pressure (port 1) in one circuit and then open and supply oil to a secondary circuit (port 2) at a predetermined pressure. A typical application would be when maintained clamping pressure is required in the primary circuit while work is being performed in the secondary circuit.

FAILED

The purpose of pressure-reducing values is to keep the secondary pressures correct in branches of hydraulic systems. Most pressure-reducing valves are open and 2 way this allows the pressure to flow freely until they reach further downstream where there is a set pressure.

FAILED

Pressure relief valves are used in hydraulic systems to limit the system pressure to a specific set level. If this set level is reached, the pressure relief valve responds and feeds the excess flow from the system back to the tank. Note: the pressure relief valve is a normally closed pressure control valve
