What are Non Return Valves?

Non Return Valves: Understanding Their Role and Importance

In industries that regulate fluid flow, non-return valves can be essential. These valves ensure that liquids or gases flow in only one direction, preventing backflow. This is crucial to systems with the potential for contamination and system damage due to reverse flows. Non Return Valves are known for their reliability and durability. They have been used in many industries including oil and gas treatment, plumbing and other water treatments. Concorde Valves and Automations has a wide range of non return valves that are suitable for a variety of applications.

What Are Non Return Valves?

Non-return (NRV) valves are designed specifically to only allow fluids and gases to flow in a single direction. The valve will close when the flow is reversed, maintaining system integrity and preventing the backward movement. Water non-return vales are used extensively to prevent backflow and protect the source of water from contamination.

Why Use Non Return Valves?

They are essential in any application that requires consistent one-way flow. Non-return check valves ensure safety and efficiency in systems.

  • Backflow contamination prevention
  • Reduce pressure surges, water hammer and other effects
  • Protection of delicate systems and equipment
  • Other components can be extended to prolong their lifespan

Application of non-return valves

Non Return Valves are used in a wide range of applications, from simple household plumbing to industrial processes. Installed in:

  • For water distribution and wastewater treatment: to prevent contamination.
  • To stop the water draining in reverse.
  • For HVAC systems: to maintain constant pressure
  • The pharmaceutical and food industries: where safety and hygiene are paramount.

There are many types of non-return valves.

non-return types are available to meet different industrial requirements. Each has unique features tailored for specific applications. Here are some of the most popular types on the market.

Swing check valve

The disc of a swing check valve opens to let the flow through and then closes again to stop backflow. These valves are perfect for water distribution systems that have a constant flow direction.

Ball Check Valve

Ball Check Valve blocks backflow by using a ball that is either spring-loaded, or gravitationally-based. They are used in systems with low pressure and they are especially effective when it comes to wastewater management.

The Lift Check Valve

Lift check valves have a disc that moves up and downward within the body of the valve, which allows fluid to flow in only one direction. They are used in high-pressure chemical applications.

Wafer Check Valve

They are lightweight and compact. Installing them between flanges is easy. These valves are ideal for pipeline systems that have limited space and minimize pressure drops.

What are Non-Return Valves?

Non-Return Valves for Water in water distribution and supply systems are vital to ensure potable water is not contaminated. The valves are designed to prevent non-potable or wastewater from flowing back into clean water. This is important for urban water networks.

Use of non-return valves in water systems has many benefits

  • Protects Water Sources from Cross-Contamination: No return valves ensure public safety and health by protecting water sources against cross contamination.
  • Reducing System Strain Allowing unidirectional flow reduces pressure surges that could damage the system.
  • Improves System Reliability: By eliminating potential system disruptions and reverse flow problems, they improve the reliability of systems.

Selecting the right non-return valve

  • System pressure: Different Valves Handle Specific Pressure Ranges.
  • Fluid Characteristics: The flow rate and viscosity of the fluid are critical to the valve’s function.
  • Materials Compatibility: The materials that are compatible with non-return valves include stainless steel, brass or PVC. Depending on fluid composition, application, and environmental conditions, the choice will vary.

Installing and maintaining non-return valves

Installation of non-return valves can be done by anyone, but professional assistance is recommended when installing high pressure systems. The valve will perform better and more efficiently if it is installed correctly. Inspection and regular maintenance such as checking the valve for wear or debris can extend its lifespan.

Maintenance Tips

  • Check for Wear and Damage Periodically: Regularly check the product to see if it has worn out or damaged.
  • Remove debris: Clean up any obstructions to avoid malfunction.
  • Lubricate Moving Components: For certain types of moving parts, lubrication can reduce friction and wear.
