Syveco Swing Check Valves are essential components designed to prevent backflow in various fluid systems, ensuring efficient and reliable operation. These valves feature a simple yet effective swing mechanism that opens with forward flow and closes with reverse flow, minimising pressure loss and turbulence. Made from durable materials, they are suitable for a wide range of applications, including water, oil, and gas systems, offering long-lasting performance and low maintenance requirements.

Key features and benefits of Syveco Swing Check valves

Key Features

Swing check valves are designed to allow fluid flow in one direction while preventing backflow. They achieve this through a hinged disc, also known as a flapper, which swings open when fluid pressure pushes against it, allowing flow in the forward direction.

Key Features

The design of swing check valves allows for a full, unobstructed flow path, reducing pressure drop across the valve. This feature makes them particularly suitable for applications involving fluids with suspended solids or high flow rates, as the unobstructed flow path minimises the risk of clogging.

Key Features

Swing check valves are known for their durability and low maintenance requirements. They are often constructed from robust materials such as cast iron, stainless steel, or bronze, which enable them to withstand various pressures and temperatures.

Syveco offers the 301 series brass single-plate swing check valve, featuring a cylindrical BSP female threaded connection and a metal seat, suitable for water supply, distribution, and drainage systems. Additionally, the 302 series single-plate swing check valve is available with a female BSP cylindrical threaded connection and an EPDM PN10 seat, making it ideal for water supply, distribution, and drainage applications. Both series are designed to ensure efficient flow control in various systems.

Syveco offers the 321 series brass swing check valve, featuring a single plate design with a cylindrical BSP female threaded connection and a PN16 metal seat. This valve is perfect for water supply, distribution, and drainage systems. Additionally, the 322 series brass swing check valve shares the same single plate design and connection but includes a PN16 EPDM seat, making it equally suitable for these applications. Both series provide reliable performance in various water systems.

Size Range:	3/8" to 2" (DN10 to DN50")
PS (Bar) Range:	16
Body Material:	CW617N Brass
Seat Materials:	Metal & EPDM
Temperature Range:	0°C to 90°C (321) & 0°C to 60°C (322)

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, Actuation Valve offers sustainable spares and replacement parts for ongoing maintenance schedules.

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.
