Dual Plate Check Valve Supplier in Surat
The Dual Plate Check Valve is designed for applications where automatic prevention of reverse flow is required in a pipeline. Its two-plate arrangement opens when forward flow creates sufficient force and closes as the flow reduces or begins to reverse. The source describes a torsion spring-assisted closure mechanism intended to reduce water hammer and support non-slam closing.
Its compact wafer-style construction can help reduce the space required between pipeline flanges. The source lists cast iron, ductile iron and stainless steel body construction, alongside different disc and plate material options. Integrally moulded rubber lining may be available in EPDM, nitrile, neoprene, Viton or silicone, depending on the specified requirement.
The listed design references are IS 13095 and BS EN 593 (BS 5155). The source also describes end connections intended for compatible ANSI B Class 125 and ASME B Class 150 flange arrangements. It lists a PN 16 test pressure rating, a shell test pressure of 24 bar, a seat test pressure of 17.6 bar, a maximum working pressure of 16 bar and a maximum working temperature of 90°C for the described configuration.
These ratings must be checked against the exact model and materials offered. The listed test pressures are not interchangeable with the maximum working pressure. Buyers should provide their line specifications and request confirmation of the applicable data sheet before finalising the order.
Allarakhu and Sons can be contacted in Surat for product enquiries and assistance identifying the configuration required for an industrial project.

Size Range
The supplied source does not clearly specify a size range for the Dual Plate Check Valve configuration described above.
Before requesting a quotation, share the required nominal diameter or DN size. Confirm availability, face-to-face dimensions and mating flange details against the selected model.
Connection Options
The source describes a wafer-style valve designed to fit compatible flanges and lists ANSI B Class 125 / ASME B Class 150 flange arrangements.
Before ordering, confirm:
-
Required flange standard and drilling.
-
Nominal pipe size and flange rating.

Whether the selected valve is compatible with the existing pipeline.
-
Installation orientation and the required flow direction.
Do not assume that every body material or size is available with every flange configuration.
Design and Construction
Wafer-style body
The compact body is designed to fit between compatible pipeline flanges. This can help reduce the space required for installation compared with some conventional valve arrangements.
Dual-plate mechanism
Two plates respond to forward and reverse flow conditions. Spring-assisted closing helps the plates return towards the closed position as flow decreases or reverses.
Body and plate materials
The source lists cast iron, ductile iron and stainless steel body options. It also describes stainless steel CF8/CF8-M discs and cast iron or ductile iron plates across its listed configurations. Confirm the actual material combination for the required model.
Seat and lining options
The source lists EPDM, nitrile, neoprene, Viton and silicone lining options according to requirements. Selection should consider the fluid, temperature and operating conditions.
Pressure Information
The supplied source lists the following values for the described dual-plate check valve configuration:
-
Maximum working pressure: 16 bar (230 psig).
-
Shell test pressure: 24 bar (340 psig).
-
Seat test pressure: 17.6 bar (250 psig).
-
Test pressure rating: PN 16.
-
Maximum working temperature: 90°C.
Important: Test pressure is not the same as working pressure. Confirm the allowable operating conditions for the selected valve, including the effect of body material, seat material, fluid and temperature. Do not apply these values automatically to every model or configuration.
Applications
Potential applications should be assessed against the actual valve materials and operating limits. The dual-plate mechanism may be considered where automatic reverse-flow prevention is required, including:
-
Industrial water circulation and distribution.
-
Pump discharge piping.
-
Utility and process pipeline systems.
-
Water-treatment equipment.
-
Industrial cooling-water lines.
-
General fluid-handling systems compatible with the selected body and seat materials.
These are general application considerations, not a guarantee of suitability for every service. Confirm compatibility before using the valve with chemicals, steam, gases, abrasive fluids or other demanding media.
Product Selection Guide
When selecting a Dual Plate Check Valve, evaluate the following points before requesting a quotation.
Operating conditions: Identify normal and maximum working pressure, operating temperature and any pressure surges.
Fluid compatibility: Share the fluid or media name and any relevant concentration or operating details. The body, plate and lining materials must be suitable for the service.
Pipeline size: Specify the required nominal diameter or DN size and pipeline details.
Flange standard: Provide the applicable flange standard, rating and drilling details so compatibility can be checked.
Installation orientation: Confirm whether the valve will be installed horizontally or vertically and follow the selected model’s installation instructions.
Sealing requirements: Discuss the required seat or lining material and the acceptable leakage requirements for the application.
Documentation: Request the current technical data sheet and applicable test documentation for the exact model being quoted.

Frequently Asked Questions
What is a Dual Plate Check Valve?
A Dual Plate Check Valve is an automatic valve designed to help prevent reverse flow in a pipeline. Its two-plate mechanism responds to changes in flow direction.
How does a Dual Plate Check Valve work?
Forward flow opens the plates. As flow decreases or reverses, the plates move towards the closed position. In the configuration described by the source, torsion spring assistance helps the valve close and reduces water-hammer effects.
What materials are listed for this valve?
The source lists cast iron, ductile iron and stainless steel body construction options. Disc, plate and lining materials depend on the selected configuration and should be confirmed before ordering.
What is the maximum working pressure?
The supplied source lists a maximum working pressure of 16 bar (230 psig) for the described configuration. Confirm this against the exact model and its current technical documentation.
What is the maximum working temperature?
The source lists a maximum working temperature of 90°C for the described configuration. The permissible temperature may depend on the selected materials and should be verified before use.
What are the listed shell and seat test pressures?
The source lists a shell test pressure of 24 bar (340 psig) and a seat test pressure of 17.6 bar (250 psig). These are test values and must not be treated as the maximum working pressure.
Can the valve be installed horizontally or vertically?
The source describes the valve as suitable for horizontal or vertical installation. Confirm the installation instructions and flow-direction requirements for the specific model.
Which flange standards are listed?
The source lists compatibility with ANSI B Class 125 and ASME B Class 150 flange arrangements. Confirm the exact flange drilling and connection requirements before ordering.
