Dual plate check valve manufacturers in Italy

Valvesonly Europe one of the excellent Dual plate check valve manufacturers in Italy, provides high-performance valves made to satisfy the requirements of many industrial applications. To guarantee enduring performance under demanding operating conditions, our valves are constructed with accuracy and robustness.
In industrial pipe systems where backflow prevention is crucial, dual plate swing check valves are indispensable parts. In order to maintain the system’s efficiency and safety, these valves are made to let flow in a single direction while blocking reverse flow. Dual plate swing check valves, in contrast to conventional swing check valves, have two plates that swivel on a hinge to increase sealing and lower pressure drop.

Why Do Dual Plate Swing Check Valves Need to Be Used?
Dual Plate Swing Check Valves are necessary to stop backflow in industrial systems. Backflow contaminates, pressure surges, and equipment damage can result in operational failures and higher maintenance expenses. Dual plate swing check valves are extensively applied in the following industries:

Oil and Gas – To avoid reverse flow in pipes.
Water and Wastewater Treatment – To prevent contamination and pressure surges.
Power Generation – To ensure system stability and avoid pumps and turbines damage.
Chemical Processing – To treat hostile fluids and avoid chemical mixing.
The valves prevent the flow from reversing, guarding delicate equipment and preserving system efficiency.

Installation Guide:

Dual plate swing check valves must be installed correctly for optimum longevity and function. The following are important rules:

Flow Direction: Verify that the arrow on the valve body indicates the proper flow direction, which is where the valve should be fitted.
Positioning: The system design will choose whether to install the valve vertically or horizontally.
Clearance: To facilitate simple access during maintenance, leave enough room surrounding the valve.
Using the proper flange connections, secure the valve to stop leakage.
Testing: To ensure correct performance following installation, perform a pressure and flow test.

By following these instructions, you may prolong the valve’s lifespan and guarantee smooth performance.

What is a Dual Plate Wafer Check Valve?

A Dual Plate Wafer Check Valve is a reduced size form of the dual plate swing check valve, ideal for space-saving installations. Wafer design permits straightforward installation between two flanges with no additional support of pipe. It incorporates two spring-loaded plates that move in and out of the line of flow upon change of the direction of flow of the medium, providing quick action and minimal pressure drop.

Benefits of Dual Plate Check Valves:

Less Pressure Drop: Dual plate configuration minimizes the flow resistance to achieve system efficiency.
Lightweight and Compact: The smaller size lowers the weight and total size, facilitating installation.
Fast Action: Spring-loaded plates provide fast closure to keep backflow and water hammer from occurring.
Corrosion Resistance: Offered in stainless steel, duplex steel, and other corrosion-resistant alloys.
Low Maintenance: The strong construction needs less maintenance, lowering the cost of operation.

Functions:

Prevent Backflow: Make sure the medium only flows in one way by preventing backflow.
Protect Equipment: Avoids reverse pressure, which can harm compressors and pumps.
Cut down Water Hammer: Pressure spikes are lessened by the fast- closing mechanism.
Preserve System Integrity: Assists in keeping the system’s pressure levels steady.

Parts:

Body: Offers structural integrity and houses the internal parts.
Plates: The two hinged plates that open and close in response to the medium’s flow are called plates.
Spring: The spring ensures that the plates close quickly and smoothly.
Hinge: The hinge pin gives the plates their pivot point.
Seat: Guarantees a secure closure to stop leaks.

Types:

Wafer Type Dual Plate Swing Check Valve: Ideal for installations with limited space because it is lightweight and compact.
Dual plate swing check valve of the flanged type: Designed to withstand high temperatures and pressures.
Lug Type Dual Plate Swing Check Valve: Simple alignment and secure installation are provided.
Cryogenic Dual Plate Swing Check Valve: For applications requiring extremely low temperatures.

Dual Plate Swing Check Valves are used for backflow protection with low pressure drop. Both plates are centre-hinged to swing open on flow and close when the flow is shut. The spring loading facilitates rapid closing, avoiding water hammer and pressure surges. The valves are made of top-quality materials including stainless steel, duplex steel, and alloy steel, providing a long life without corrosion.
