Class 300 Ball Valve are made of floating ball valve or trunnion mounted ball valve, size from 1/2 to 40 inch with flanged or welding ends. Class 300 ball valves can withstand the maximum pressure rating 50 bar during the temperature -29/38℃. The high pressure seat test is 56 bar, shell test pressure is 76.6 bar for carbon steel body.

ANSI Class 150 ball valve sizes up to 40 inch.A class 150 ball valve can withstand a pressure rating up to 20 bar during operationat —20 to 100°F (—29 to 38°C), as listed in ASME B16.34. a Class 150 ball valve is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F. In other words, when the pressure goes down, the temperature goes up.

Class 600 ball valves are designed to the latest ASME B16.34. All the ANSI Class 600 ball valve are tested around 110 bar for high pressure seat test according to the material of valve body. The Face to face dimensions and bore sizes are as per API 6D. Contact us for Class 600 ball valve price.

Metal Seated Ball Valve is manufactured for high temperature or abrasion resistance. Relia Metal Seated Ball Valves are Zero leakage (bubble tight seal).

Fully welded ball valves are with the advantages that the ball valve is integrally welded without external leakage path. Non-destructive tests (NDTS) are performed. Fully welded ball valves, all welding processes for the body are suited to the materials of construction and are qualified and performed according to ASME Section IX. Non-destructive tests (NDTS) are performed per ASME VIII Division 1, App. 12.

Cast Steel Gate Valve with flexible wedge gate are made of carbon steel, stainless steel, alloy steel and duplex steel. All API 600 trim no. is available, such as API 600 trim no. 1, 5, 8, 10, 12 etc.

Cast Steel Globe Valves are valves with flanged or butt welding end connection designed with BS 1873 or API 627 standards and widely used in oil, gas, and petrochmeical industry.

Cast Steel Check Valves are offered in swing check, piston check and tilting disc check styles, with the seat hard faced for durable appliations.

Top Entry Ball valves are trunnion mounted ball, in-line repairable and ensure bi-directional sealing; they feature one piece body & double block and bleed.

Forged Steel Gate Valves are Bolted Bonnet, outside screw and yoke type, Rising Spindle construction Body and bonnet made from high quality forgings.

Forged Steel Globe Valves are generally available with Plug type disc. Forged Steel Globe Valves are designed to give leak tight seating over a long period of in built wear life.

Wafer check valves are with wafer, wafer lug or flanged ends connection, in dual plate disc, single dist for option. Relia wafer check valves are reliable sealing performance and durable application.
