Advantages of Pressure Limiting Valve
Protects Your Plumbing System
Burst pipes due to excessive water pressure are among the most dreaded plumbing disasters. These incidents can result in significant repair costs and disruptions to your daily life. However, with a PLV in place, the pressure of the water flowing through your pipes is kept in check, providing a robust defense against potential damage.
Saves Water
High water pressure can also cause leaks in your plumbing system, which can waste a significant amount of water. A PLV can reduce the pressure of the water, preventing leaks and saving water.
Extends the Life of Your Appliances
Your household appliances, such as washing machines, dishwashers, and hot water systems, rely on an appropriate water pressure range to function efficiently. Excessively high water pressure can strain and damage these appliances, leading to premature breakdowns.
PLV Can Help Reduce Your Water Bills
A PLV can help reduce your water bills by preventing leaks in your plumbing system. By reducing the pressure of the water, a PLV can prevent leaks, saving you money on your water bill. High water pressure can cause damage to your plumbing system and appliances, leading to costly replacements.

Types of Pressure Limiting Valves
Manual Pressure Limiting Valves
These require manual adjustment to set the pressure limit. They are suitable for systems with frequently changing pressure conditions but may lack precision compared to automated options.
Electrically Controlled Pressure Limiting Valves
These use electronic controls to maintain precise pressure levels automatically, adjusting without manual intervention. They often include advanced monitoring systems that provide real-time data and alerts, enhancing system safety and efficiency.
Applications of Pressure Limiting Valve
Water Distribution
Protecting pipes and fixtures from high pressure.
Industrial Processes
Ensuring equipment operates within safe pressure limits.
Gas and Oil
Managing pipeline and storage pressure to prevent leaks and hazards.
Household Plumbing
Safeguarding appliances like water heaters and washing machines from excessive pressure.
Production Process of Pressure Limiting Valve
Procurement Of Raw Materials: In the manufacturing process we require steel casting of various grades, stainless stall round bars, forging, hardware (nuts & bolts), gaskets, paints and also packing materials.
Machining: The raw materials is issued to the machine Shop for machining through material requisition slips. Valve body, bonnet, valve seat, spindles etc are machined on centre lathe machine, after which all lie components are checked by vernier callipers or micrometers.
In Process Testing: If It Is found to be OK dimensionally and visually, the valve, body and bonnet are sent for Hydrostatic Testing to the testing yard and other components are sent to the fitting / assembling department.
Assembly: The body and bonnet which are hydrostatically OK are sent to the filing shop for assembly, duly handled with care so that there are no scratches on the machine surfaces. In the fitting shop, body and bonnets are drilled on drill machine with the help of Jigs and fixtures for uniformity and interchangeability by Quality Assurance Department and passed, or sent back.
Lapping: In some cases lapping of the seats and plugs / other components is done prior to fitting, whereas in other cases lapping is done after fitting.
Testing: After assembly the new complete valves is sent for hydrostatic testing again. If no leakage is observed as per the relevant standards, it is sent to the finishing department
Finishing /Painting: Here the valve body surface is debarred and finished by sanders and flexible shaft grinders for better appearance and smooth finishing.
Final Inspection: After painting, Final Inspection is done by our Quality Assurance Department & Third Party inspection Agency, whose responsibility now is to co-relate and check all records relating to the valve concerned.
Installation Requirements of Pressure Limiting Valve
To get the best performance, always mount pressure limiting valves vertically. Ensure the valve is installed correctly by following the arrow that shows the fluid flow direction.
Keep the inlet piping short, direct, and at least as wide as the valve to avoid flow issues. Support the outlet piping well to prevent warping and ensure it can handle the flow without strain.
It’s important to ensure that the valve is compatible with the fluids in the system. Factors like temperature, environmental conditions, and exposure to corrosive substances should be considered when selecting and maintaining pressure limiting valves. The operating pressure should be set below the valve’s maximum set pressure. This precaution helps prevent unexpected pressure spikes that could compromise system safety.
