Three piece forged structure; Class BA inner chamber, fireproof design, replaceable valve seat, anti flying valve stem structure

The valve stem is designed with dual sealing, and the ball valve has a compact structure and maximum flow design. It is widely used in various harsh conditions such as high pressure and frequent switching.

The floating ball core can be sealed in both directions, and the hard loaded valve seat has good sealing performance in both low-pressure and high-pressure systems.

Fireproof design, anti flying stem structure, all apertures have been fully manoeuvrable pressure tested.

Suitable for sour gas environments, with materials meeting NACE MR0175/ISO 15156

Each valve shall undergo a sealing test with 10 MPa nitrogen before leaving the factory, and shall be sealed at a pressure of 2% and 1.1 times the rated working pressure
