Spring Loaded Non Return Valve Supplier in Surat
The Spring Loaded Non Return Valve is intended for applications that require automatic control of reverse flow without a separate manual operating mechanism. During forward flow, the pressure of the moving fluid acts on the internal closing element. When flow reduces or reverses, the spring-assisted mechanism helps return the element towards the closed position.
The supplied product source lists a stainless steel SS304 (CF8) construction and describes the valve as a spring-loaded non-slam check valve. The listed size is 4 inches, with PN40 shown as the operating-pressure designation. Oil is the specified media, and the stated working temperature is 100°C. The source also records a hydrostatic test value of 40 kg/cm².
A suitable valve must be selected against the real operating conditions of the pipeline. Buyers should confirm the exact pressure rating, temperature limits, connection type, dimensions, spring arrangement and fluid compatibility from the current technical datasheet. The source listing does not establish a complete size range or all available connection options for this product.
Allarakhu and Sons, based in Surat, can be contacted for a product enquiry. Share the project specifications and required quantity so the relevant product configuration can be checked before quotation.

Size Range
The supplied listing specifies a 4-inch valve. It does not confirm the complete size range available for this product.
If your project requires a different size, contact Allarakhu and Sons to check availability and confirm the dimensions for the required configuration.
Connection Options
The supplied listing does not clearly identify the end connection for this exact valve. Do not assume that it is threaded, flanged, wafer type or socket-weld without confirmation.
Before ordering, verify:
-
Required nominal pipe size.
-
Connection type and dimensions.
-
Mating pipeline or flange requirements.
-
Face-to-face dimensions, where applicable.
-
Installation orientation and flow direction.
-
Space available for installation and maintenance.
Design and Construction
Stainless steel construction
The source lists SS304 (CF8) stainless steel. Confirm the material designation in the quotation or technical documentation if your project requires material traceability.
Spring-loaded mechanism
The spring-assisted mechanism helps return the closing element towards its seat when forward flow reduces or reverses. This supports automatic non-return operation.
Non-slam design
The source describes the product as a non-slam check valve. Actual closing behaviour depends on the valve design and the pipeline’s flow conditions. Confirm the manufacturer’s performance information if water hammer or pressure surges are a critical concern.
Fluid compatibility
Oil is the media listed in the source. Compatibility depends on the specific oil, temperature, pressure and internal sealing materials. Confirm suitability for the actual fluid before installation.
Pressure Information
The supplied listing includes two separate pressure details:
-
Operating pressure designation: PN40.
-
Hydrostatic test value: 40 kg/cm².
These details must not be treated as equivalent. A test pressure is not automatically the permitted working pressure, and a pressure designation alone does not confirm the allowable operating conditions at every temperature.
Before purchasing, ask for the current datasheet confirming the maximum allowable working pressure, temperature limits, test procedure and applicable standard for the exact model.
Applications
The source identifies oil as the media for this valve. Its suitability for a specific oil-handling system must be checked against the fluid properties and operating conditions.
Potential applications to assess include:
-
Oil-handling pipeline systems.
-
Industrial fluid-transfer lines.
-
Pumping systems requiring reverse-flow prevention.
-
Industrial process lines where a spring-loaded non-return mechanism is specified.
-
Maintenance or replacement projects requiring a compatible spring-loaded check valve.
These are potential application areas, not a guarantee of suitability for every installation. Confirm the fluid, operating pressure, temperature, connection type and relevant safety requirements before selecting the valve.
Product Selection Guide
Use these checks when selecting a Spring Loaded Non Return Valve for an industrial project.
Valve size: Confirm whether the listed 4-inch size matches the pipeline.
Material: Verify whether SS304 (CF8) is suitable for the fluid and surrounding conditions.
Pressure: Check the required operating pressure against the exact model’s allowable working-pressure rating.
Temperature: Compare the normal and maximum operating temperatures with the manufacturer’s approved limits.
Media: Identify the specific oil or process fluid and confirm material compatibility.
Connection: Confirm the required connection type and pipeline dimensions before ordering.
Non-slam performance: If pressure surges are a concern, ask for the manufacturer’s performance information for the intended flow conditions.
Documentation: Request the current technical datasheet and any required test or inspection documents.
