110mm non return valve

Types of 110mm non-return valve

110mm non-return valve is a plumbing essential and comes in various types. These include:

• Swing Non-Return Valve

  A swing non-return valve does not open unless the medium exerts pressure on it. When the pressure drops, the valve closes. Channels with large flow rates, such as pipes, use swing NRVs. They close tightly, preventing backflow.

• Check Non-Return Valve

  The internal disk in a check valve is its distinguishing feature. This disk moves in response to pressure changes. Fluid flows through the valve when the pressure inside the pipe is higher than outside. The disk closes to prevent backflow. Simple but vital in many systems.

• Dual Disc Non-Return Valve

  Like the check valve, a dual disc valve has two discs. They open and close more quickly than single-disc valves. This rapid operation reduces water hammer. Water hammer is a series of pressure waves that cause pipes to shake.

• Lift Non-Return Valve

  Lift NRVs resemble lift checks but lack the release switch. They lift the disc, allowing flow, and close when flow stops. These NRVs work best at high pressure and small pipe diameters. They help protect equipment in oil and gas pipelines.

• Ball Non-Return Valve

  This valve uses a ball as a seal. It rolls away during flow and back during no flow. Ball valves offer quick operation, durability, and resistance to wear and tear. Industries use them for their ability to handle sediments and solids.

Function, Feature, and Design of 110mm non-return valve

Function

A 110mm non-return valve prevents fluid backward movement in pipes and systems. Thus protecting equipment, tanks, and filters from damage. It ensures systems operate safely and efficiently. Non-return valves are hence crucial in plumbing, and water treatment and cutting down on contamination.

Features

These valves' features include:

• Prevents Backflow: The main job of a non-return valve is to stop backflow. All types do this effectively. They protect equipment and ensure systems function as they should.
• Variety of Designs: Non-return valves come in various designs. Each design depends on the industry or system that needs it. Common designs are swing, lift, check, dual disc, and ball.
• Automatic Operation: Non-return valves open or close automatically. This auto-opening or closing is depending on pressure changes. Some do this with manual levers. Most, however, are automatic.
• Different Materials: Non-return valves come in different materials. These materials include brass, stainless steel, and PVC. PVC is cheaper but not as strong. Stainless steel is more expensive. Each material has its pros and cons.

Design

Non-return valves in the plumbing field have internal parts. These internal parts enable them to function. The most common ones are:

• Disc: The disc is the part of the valve that blocks flow. In swing valves, the swing is the part that swings. Check valves have discs that close and open. Lift valves have discs that lift and drop. All these discs play a blocking role.
• Seal: Seals ensure no fluid leaks when the valve is closed. They are important for preventing contaminants from entering systems. Seals wear with time, so replace them when needed.
• Spring: Springs return the disc to its original position. They ensure the valve closes tightly when not in use. The absence of springs in some valves like springless checks means tighter manual control. This ensures backflow is always stopped.

Scenarios of 110mm non-return valve

There are many scenarios where these 110mm non-return valves are useful. Some of these scenarios include:

• Preventing Contamination in Water Treatment

  Non-return valves in water treatment ensure contaminated water does not enter clean water systems. They are after filtration or disinfection. The issue with backflow is that it reverses the flow of treated water, bringing it to point A where it started. This point A is never good for the water’s health.

• Agricultural Irrigation Systems

  Farmers use irrigation systems closely. These farmers install non-return valves to prevent irrigation water from going backward into storage tanks. Going backward not only reduces water supply but also brings diseased water that can harm plants. The valve ensures a constant supply of clean water.

• Industrial Processes

  Manufacturing plants mix chemicals and use high-pressure liquids. They implement non-return valves to prevent mixture or chemical flow back into the pipe. Not doing this can cause pipelines to burst, leading to high repair costs. The valves also ensure the chemicals do not contaminate the drinking water supply near the plants.

• Fire Protection Systems

  Fire sprinklers and systems use pumps to move water. Non-return valves stop water from moving back into the water supply. It ensures firefighters have access to uninterrupted water during emergencies.

• Submarines and Ships

  Non-return valves are on submarines and ships to control air and fluid movement. They ensure compartments remain watertight and protect the ship's internal systems from external pressure. Non-return valves are also used in propulsion and exhaust systems to allow flow in only one direction.

How to Choose 110mm non-return valve

Selecting the ideal non-return valve for clients’ needs takes careful consideration. Below are some of the things a business owner should consider:

• Valve Material

  Non-return valves are made from different materials. Each material has its pros and cons. These materials are brass, stainless steel, PVC, and more. PVC is cheaper. It is also non-corrosive. Thus, ideal for first-time buyers who want to experiment. Brass is affordable but relatively weak. Stainless steel is expensive, and corrosion-resistant. It is most suited for long-lasting products.

• Valve Size

  Non-return valves come in various sizes, with the 110mm being the most popular. Businesses with DIY customers should advise their customers to measure pipe diameter before buying. The right size will fit easily without any modifications. If there’s no 110mm size available, get close sizes. The closest size is better than none.

• Type of Fluid

  Different non-return valves are suited for different fluids. Some can withstand high temperatures, while others can’t. Some can withstand high pressure, while others can’t. Buyers who want to buy pneumatic valves should ensure they get the lift or the ball non-return valve. It is ideal for gas applications.

• Installation

  Non-return valves are easy to install. Some, however, are easier than others. Swing and check valves are easier than lift and pressure valves. If intending to sell owners who will install the valve themselves, get easy-installing valves. Also, consider purchasing valves with prefixed flanges. These types have flanges that don't need to be welded onto the pipe.

• Operating Pressure

  Business owners should get high-pressure non-return valves. Hydro test many of them to ensure they withstand high-pressure. Such valves are longer-lasting. They act as a safety measure for the industry. Also, remind customers to always go for valves that can withstand the industry’s pressure range. The pressure difference between this range and the operating pressure can cause the valve to fail.

Q&A

Q1. Do non-return valves have to be horizontal?

There’s no specific direction for the non-return valves' installation. However, horizontal installation is preferred for swing-type valves. This is because horizontal installation allows the swing to swing freely.

Q2. Can non-return valves be installed vertically?

Yes, non-return valves can be installed vertically. However, it is important to note that the vertical installation method may affect the valve's performance. The swinging mechanism may not function smoothly, especially in the 110mm non return valve kit.

Q3. What is the difference between a check valve and a non-return valve?

There’s no difference at all. A non-return valve is simply a check valve that stops pipes from flowing backward. They do this by closing when the pressure drops below a certain point.

Q4. How do I choose a non-return valve?

Choose the valve that will serve clients’ needs the best. Bear in mind the fluid, pressure, and industry temperature. Getting the right valve for the intended application will improve performance and protect the system.
