LNG 2" Cryogenic Ball Valve Stainless Steel Flanged DN 50 1.6Mpa-42Mpa

2'' Small Size Cryogenic Ball Valve Stainless Steel Flanged Connection

Product Description

Liquid nitrogen cryogenic treatment is an indispensable process for cryogenic ball valve manufacturing. The ball valve

adopts thedesign of extended bonnet and drip tray to ensure the sealing performance of the stuffing box and the normal

operation of the valve. According to the characteristics of the sealing structure of the valve seat, the single-piston effect

valve is mainly analyzed. The structural characteristics and sealing principle of the seat and the double-piston effect valve

seat,the sealing direction of the two is different due to the different structural characteristics of the seat and the valve body seal.

Specifications

Performance Feature

1. Cryogenic Ball Valve Extension Bonnet Structure: assure the stuffing box sealing performance,prevent frost on stuffing box.

2. Automatic Pressure Relief Seat: avoid cavity pressure abnorrnal rising.

3. -196℃ liquid nitrogen cryogenic treatment:turn the remaining austenite into martensite,prevent componet dimensional change from organization phase transformation cause by temperature change.

4. Nitrogen Test Leakage:assure valve sealing performance,ensure valve is applicable to wide range of application.
