Pressure Control Valves are available in a range of sizes and designs to suit your requirements. These types of valves are often used in process control applications such as material handling, food processing, and conveyor systems.

Generally, a pressure reducing valve has several important functions. It is designed to maintain a reduced pressure in a defined area of the hydraulic system, such as a pump or cylinder.

It works by using a pressure spring to withstand the high system pressure. This allows other branches to operate at full system pressure. If the system pressure rises too high, the valve is triggered and the flow is restricted.

A pressure reducing valve is also used to reduce the pressure in a single branch. The valve can be set to open at a fixed or adjustable timed pressure. However, it should not be used on all branches of the system.

Direct-acting relief valves are another type of pressure control valve. These are used to relieve pressure from a cylinder or pump by blocking the flow until it reaches the poppet or ball of the valve. They may be manual, automatic, or electrical.

There are also many more types of pressure control valves. Some of the most common include cartridge, unloading, pressure sequence, and pressure reducing valves.

Several manufacturers produce hydraulic pressure control valves. For example, Longwei has a line of valves for general industrial applications. Their two-stage balanced piston design is ideal for controlling the flow of hydraulic fluid in hydraulic systems.
