Salient
Features :
* Spring closing arrangement for the prevention of reverse
flow in pipe lines.
* These valves are general purpose valves that are stronger,
lighter and smaller
than conventional Swing Check valves and
therefore, less expensive to install and
maintain.
* Suitable for higher pressure / temperature (upto 4000
c)
* Compact Design for simple installation between a wide range
of flange types.
* It can be mounted in any plane / direction.
* Extremely low opening pressures.
* Available sizes 15mm to 100mm, suitable for PN6-PN40 and
ANSI 150/300
* Weight and Dimensions are same for class 150 & class 300
valves.
* Valves are self centering type.
* Zero leakage for soft seated valves.
* The maximum permissible leakage rate shall be 3 cubic
centimeter per minute
per inch of nominal pipe size for metal seated
valves.
* Design : As per manufacturers standard.
* Testing : As per API 598.
