Check Valves

Check valves, also known as non-return valves or one-way valves, are used in fluid systems to control the flow of liquids or gases. Their primary function is to allow the flow of the fluid or gas in one direction while preventing or significantly restricting the flow in the opposite direction. Check valves are designed to open and close automatically, based on the pressure and flow direction of the fluid or gas. Actuation Valve work with Abacus and LVF to supply industry-leading check valves for your business needs.

Frequently Asked Questions

A check valve is a one-way valve that allows fluid to flow in one direction while preventing backflow. It operates using a swinging, lifting, or tilting disc or a spring-loaded mechanism to control the direction of flow.

Check valves find applications in a variety of industries, including water and wastewater systems, oil and gas pipelines, HVAC systems, and industrial processes.

Check valves provide reliable and continuous operation, preventing reverse flow, minimising the risk of contamination, and ensuring system integrity without the need for external power sources.

Yes, check valves come in various types, including swing check valves, lift check valves, dual-plate check valves, and more, each designed for specific applications and conditions.

Check valves generally require minimal maintenance but should undergo periodic inspections and potential lubrication to ensure proper functioning.

Most check valves are designed to function in both horizontal and vertical orientations, but it's essential to follow the manufacturer's installation guidelines for optimal performance.

The cracking pressure is the minimum pressure at which a check valve starts to open. It varies based on the valve's design and specifications.

Check valves can be designed for high-pressure applications, but their suitability depends on the valve's specific pressure rating and construction materials.

Check valves are primarily designed to prevent backflow and are not intended for flow rate or pressure control. Control valves are typically used for such purposes.
