Valve Design : Sealing

Pyramidal Body and Stem Seal (1st Stage): Internal pressure of the valve pushes the pyramidal stem sealing upward. Because of its shape, the sealing expands to fill all the air pockets the might become a potential leakage path in the lower stem area

Viton O Ring (2nd Stage): The elastic nature of the Viton O–Ring serves as an effective sealing for the gaseous medium that might escape the 1st stage sealing.

Stem packing (3rd Stage): The stem packing fills all the air pocket in the outer stem area. It effectively seals internal media within as well as keeping external media from entering.

Valve Design : FEA

Valves are designed using leading technologies including 3D Solid Modelling, Finite Element Analysis (FEA) to deliver tailor made solutions that meet our customer’s requirement.

Valve Design : Fire Safe Sealing

Floating ball valves Fire Safe Sealing is designed in accordance with API 607. When non-metal resilient seats are destroyed in a fire, the upstream medium pressure push the ball into the downstream metal seat lip to cut off the line fluid and prevent the internal leakage due to a secondary metal-to-metal seals.

Valve Design : Blow-Out Stem

Blow-Out Stem is designed with integral T-type shoulder to provide blow-out proof effectively. It is internally inserted as the backseat function to assure stem sealing safety at all pressures.

Valve Design : Anti-Static

Anti-static devices between ball & stem and stem & body are assembled by a spring & a stainless steel ball, which ensure all metal valve parts are grounding.
