Dikkan Counter Weight Check Valves

Dikkan swing check valves with rubber seal and full bore are commonly used in water systems where flow needs to go in one direction but be prevented from reversing. They are suitable for both horizontal and vertical installation in applications involving cold and hot water as well as fresh and seawater. The swing check valve allows flow in the forward direction by the flow itself pushing open the hinged disc or clapper inside the valve body. When flow stops or reverses, the disc is pushed shut by gravity and/or reverse pressure, preventing backflow. This automatic action provides passive one-directional flow control without the need for any external mechanisms or operator input.

Dikkan Cast Iron Counter Weight Check Valves (Without Lever)

Dikkan swing check valves are a common choice for water systems that require unidirectional flow. The cast iron bodies with full bore rubber sealed discs can be installed horizontally or vertically. They prevent backflow in pipelines carrying cold water, hot water, fresh water, or seawater.

Dikkan Cast Steel Counter Weight Check Valves (Without Lever)

The Dikkan swing check operates passively by allowing forward flow to push open its hinged clapper. When flow ceases or reverses, the clapper swings shut under its own weight and/or reverse pressure, preventing backflow without the need for external mechanisms.

Size Range: DN32-DN600 (1.25"-24")
Body Materials: Cast Steel
Body Standard: DIN 3232, Rubber Sealed
Applications: Cold and Hot Water, Fresh and Seawater.
Pressure Rating: PN16/PN25
End Connections: Flanged

Dikkan Ductile Iron Counter Weight Check Valves (Without Lever)

Ductile iron provides durability and strength. The rubber seat seals tightly to stop leakage and water hammer when closed. The full bore enables efficient high flow rates with minimal pressure loss. The compact Dikkan design fits constrained pipe runs, with no protruding parts. Its freely swinging clapper responds directly to flow conditions, closing immediately upon reverse flow.

Size Range: DN32-DN600 (1.25"-24")
Body Materials: Ductile Iron
Body Standard: DIN 3232, Rubber Sealed
Applications: Cold and Hot Water, Fresh and Seawater.
Pressure Rating: PN10/PN16
End Connections: Flanged

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.

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.
