They come with flanged and screwed BSPP/BSPT/NPT end connections, ensuring compatibility with a wide range of systems.
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.
Yes, check valves can be used for both liquids and gases. The choice of valve type and material should be made based on the specific fluid and application requirements.
