“Most fluid powered systems are designed to operate within the present pressure range. It is a function of the forces that should generate to do the required work. Relief valve void the hazards of pressure and safeguard the limit of the maximum pressure in a system. Overall, the basic purpose of the control valve is to offer a safe atmosphere and prevent the possible damages of excessive pressure.”

The primary role of control valve is to manipulate the flow of various components and make the environment safe for working.

Emersion control valves are very effective to control the direct flowing gas, steam, water and chemical compounds. It helps to contributes the load distribution and regulate the process as close as possible.

Emerson ultrasonic flow meter is an effectively designed system used by the designers to prevent uncontrolled system pressure. In fact, it is also very effective to regulate he pump flow during any standby period.

Ideally, these pressure control valves are widely used in hydraulic system to manage and control the actuator force. The actuator force is determined by a hydraulic actuator that consists of cylinder ad fluid motor. The valve is used to determine and select the pressure level.

The function of pressure control valves:

• The primary functions of the pressure control valves are listed below:

• Reduce the unload the system pressure

• It also helps to lower the pressure level from the main circuit

• Regulate the system pressure in certain parts of the circuit

• Prevent the maximum system pressure at a safe level

• Assist the operating sequence with the use of pressure control

Primarily there are two type of valves widely used to regulate pressure time to time. The two basic types of valves are pressure limiting valve and pressure-reducing valves.

Pressure control valves can safeguard the system against the excessive system pressures. It also helps to limit the operation pressure to particular system function. Pressure reducing valve maintains a large pressure event at a variable pressure.

On the other hand, shut off valve and load holding valves are also necessary components of the system. The former is responsible to receive control oil from high-pressure circuit and the latter prevent loads on motors.

Constant and Fixed Pressure Reduction

It works as a preset pressure regardless of the main circuit pressure. As long as the main circuit is higher than the secondary, the valve helps to balance the secondary circuit against the force exerted by the adjustable spring that tries to open the valve.

Fixed pressure reducing valve supplies a fixed amount of pressure reduction regardless of the pressure in the main circuit. The valve typically operated by balancing the force exerted by the pressure.
