What are the benefits of rubber-lined water valves and are they suitable for industrial use?
 In industrial piping systems, the choice of equipment to control the flow of water or liquids has a significant impact on overall performance. One popular choice in many industries is the “ rubber-lined water valve ,” which many people may not be aware of. What are the different features and benefits of this type of valve compared to conventional valves, and what types of applications are they suitable for?

This article will introduce you to rubber-lined water valves and answer your questions about whether or not they are suitable for industrial use.

– What is a water valve with a rubber lining ?

Rubber Seat Valve or Rubber Lined Valve is a valve that has a rubber sheet inside the valve body that is in contact with water or liquid. The rubber used is usually EPDM, NBR or other special rubber that is resistant to chemicals, pressure and temperature, depending on the purpose of use.

– Benefits of water valves with rubber lining

• Good leak protection
 The flexible rubber liner provides a tight seal between the valve plate and the valve body, reducing the chance of leakage even in high pressure systems.
• Reduces impact and noise when opening and closing.
 When the valve is opened or closed, the rubber absorbs shock, reducing noise. Ideal for systems that require quiet operation or gentle pressure control.
• Resistant to corrosion from certain liquids
 Some rubbers have good resistance to chemicals such as wastewater, seawater, or weakly acidic or alkaline liquids, helping to extend the life of valves in systems prone to corrosion.
• Easy maintenance
 Replacing the rubber liner or performing maintenance is often easier than with all-metal valves, reducing downtime for maintenance.

Water valves with rubber linings are suitable for use in what types of industries ?

• Water supply and wastewater systems
 Used to control the opening and closing of water in water delivery systems, water filtration systems, or wastewater treatment systems, especially those using seawater or saltwater.
• Food and beverage industry
 Because it is made of rust-free and non-contaminating materials, it is suitable for use in food production lines.
• Power plants and cooling systems
 Used to control the flow of coolant or liquid within a system that must work continuously and with high pressure.
• Petrochemical system​
 Can be used with corrosive chemicals if the appropriate rubber lining material such as NBR or Viton is selected.

Considerations when choosing a water valve with a rubber lining

1. Check the properties of the rubber to ensure it is suitable for the liquid used. For example, if used in industrial applications with high heat, choose EPDM that is heat resistant.
2. Check the pressure rating to match your system.
3. Consider the external valve body material, such as cast iron, ductile cast iron, or stainless steel , for long-term durability.
