Vertical In Line NRV – Check Valve Screwed End
The Vertical In Line Nrv – Check Valve Screwed End is an industrial non-return valve intended to help prevent reverse flow in compatible piping systems. Its in-line configuration and threaded connections make it an option for installations where the piping layout and operating conditions are suitable for this type of valve.
The product source specifies precision investment-cast construction and a full-bore design. The standard seating arrangement is metal-to-metal, while a soft seat is available on request. The appropriate seating option depends on the required sealing performance, process medium, temperature and other service conditions.
The listed size range extends from ½ inch to 2 inches, corresponding to DN15–DN50. The threaded connection references include BSP, BSPT, NPT and other listed standards. These thread forms should not be treated as interchangeable without checking their dimensions and sealing requirements.
The source lists a working pressure of 800 WOG and a working-temperature range of −10°C to 100°C. These figures should be verified against the intended operating conditions and the manufacturer’s technical documentation. The precise body material, internal-component materials and detailed installation requirements should also be confirmed before purchase.
When selecting this valve, industrial buyers should consider the nominal pipe size, thread standard, flow direction, mounting orientation, pressure-temperature conditions and fluid compatibility. Allarakhu & Sons can be contacted to discuss the required configuration and request a quotation.

Size Range
The listed size range is ½ inch to 2 inches (DN15–DN50).
Before ordering, confirm:
-
The exact nominal size required.
-
The corresponding pipe dimensions.
-
The available sizes within the listed range.
-
The thread standard and connection dimensions.
-
The installation space and flow direction requirements.

Connection Options
The source references the following thread standards:
-
BSP
-
BSPT
-
NPT
-
DIN 259/2999
-
ISO 228
-
ISO 7/1
-
BS 21
Confirm the exact connection supplied for the required valve size. BSP, BSPT and NPT threads differ in geometry and sealing characteristics, so compatibility should be checked before installation.
Design and Construction
In-Line Valve Configuration
The product is listed as a vertical in-line NRV/check valve. Confirm the permitted mounting orientation and flow-direction marking for the selected model before installation.
Full-Bore Design
The source specifies a full-bore design. Request the dimensional drawing and technical documentation if bore dimensions or flow characteristics are important to the application.
Seating Arrangement
Metal-to-metal seating is specified, with an optional soft seat available on request. Confirm the available seat material and suitability for the process fluid, temperature and required sealing performance.
Precision Investment Casting
The source describes the construction as precision investment cast. The exact body material and internal-component materials are not stated in the available information and should be confirmed with the supplier.
Pressure and Temperature Information
The product source provides these operating figures:
-
Working pressure: 800 WOG
-
Working temperature: −10°C to 100°C
Before using the valve in an industrial system, confirm the pressure-temperature limits for the selected size, material and seat arrangement. Also verify that the valve is compatible with the intended medium and the system’s operating conditions.
For critical applications, request the applicable technical datasheet, test information and material documentation before specifying the product.
Applications
The product source identifies the valve as a vertical in-line non-return/check valve but does not provide a verified application list for every fluid or installation condition.
Potential use should be assessed according to the confirmed material, pressure-temperature rating, seat configuration and installation requirements. Before specifying the valve for water, oil, air, gas or any other medium, obtain confirmation of suitability for that particular service.
