PRV or Pressure Relief Valve is used in industrial pipelines to limit or reign in the waves of pressure in pipelines. It protects the system and guarding against appliances failure against malfunctioning due to destruction by a sudden rise in pressure. These valves are generally found in industries where clean water is required.
The Reasons For The Requirements Of Pressure Relief Valves
The primary function of a PRV Valve is to safeguard and protect the longevity, property where it is located and the environment so that everyone and every other equipment is safe and protected.
In reality, it is a safety apparatus and in many exemplary situations, it is the ultimate precautionary against the loss of life and property. As it is an instrument of immense importance, it should at all times be maintained and kept in optimum working conditions to reduce loss in life and property. Every industry with PRV Valves should be alert and make sure that it is in proper running condition.
The Operating System Of The PRV Valve
The operating system of the PRV Valve depends on the pilot Singer 81 –RP method of sensing the pressure that goes upstream via a link to the inlet of the valve. The pressure sensing system and the valve both remain in a closed position until and unless the pressure crosses the pilot setting limit.
In case the pressure exceeds the pilot setting limit, then the PRV Valve instantly opens up to release the damage-causing excess pressure. As soon as the excess pressure is released, the valve automatically closes very smoothly at a speed that is adjustable until the pressure returns to the point that has been set as its limit.
Varieties In PRV Valves
There are various types of PRV Valves. They are:
• Pressure relief valve operating on the pilot sensing method
• PRV Valves that are directly operated
• Safety valves for low pressure
• The manually operated pressure safety valves
• Simple safety valves for gas industries
• Vacuum operated pressure safety valves
Features Of The PRV Valve
Certain features rule the pressure relief valves. They are:
• They are very low on maintenance
• Takes very little time to flush out and operate and is hygienic
• It reduces the chances of surges and thereby increasing the longevity of the pipeline
• Has the ability to handle very high pressure very effectively and efficiently
• Tightly closes
• When made with premium quality raw materials they can last a good many years
• The closing speed is adjustable as per requirement
• Can make use of plant air or compressed air
Applications And Uses Of PRV Valves
The PRV Valves has extensive usage and is used in many industries where the level of pressure is of utmost importance in the smooth operation of the plant. It is mainly used in petrochemical, oil & gas and power generations plants that use steam, air, gas or liquid.
The Positives And The Negatives Of The System
The primary function is to release the pressure that has built up in excess in the pipeline system of the plant and so naturally they protect and safeguard the entire system and the property. It prevents the malfunctioning of the system. It helps in maintaining the constant flow of the pressure system of the pipeline. It increases the longevity of the pipelines by preventing them from bursting.
As this is a very key component in many factories that are working with a high-pressure system, these valves should be purchased from the best PRV Valve Manufacturers in Mumbai.
