Non Return Valves

There are two types of Non Return Valve: swing check valve and spring check valve. Both are available in brass or stainless steel, a material that suits a variety of materials, be it liquid or gas. You can select different valves of different sizes to get the best solution for your requirement.

Swing Check Valve

Swing check valves are used in a variety of applications, including sewage and wastewater treatment, firefighting, energy facilities, and home items. One of the most common examples of this non return valve application is allows water to enter a toilet tank while preventing reverse flow.

A swing check valve is a simple instrument designed for the one-way flow of a fluid or gas. It has a disc pivot on a hinge, opening to allow fluid to flow in, then sealed to prevent backflow. Swing check valves are designed with diverse elements to suit distinct application types.

Spring Check Valve 

Spring check valves generally have concave bodies and a large stopper, which requires constant spring pressure. When gas or fluid streams forward at adequately high strain, the force will overcome the spring’s stress and lead the stopper to open, permitting the desired flow.

Unlike swing check valves, spring check valves offer reasonably low noise levels. They also miscalculate the sound and adverse effects of water hammers. This style of non return valve functions well in upright applications, as it utilises a spring to close the valve rather than depending on gravity and pressure.

Applications of Non Return Valve

Swing check valves are prefered because they work well with a wide range of mediums, from liquids to gases. As a result, they can be used in a variety of fields where various materials are handled. Swing check valves work well with firefighting equipment, flood prevention in sewage systems, and conventional toilet flush components.

Spring check valves are excellent for a variety of purposes in water pipelines and systems. This sort of valve protects gear from backflow damage, minimising the risk of system downtime and potential contamination. Furthermore, spring check valves can remove pressure from the system to create a safer environment and assure appropriate system function.
