1、Product design according to NB/T 47044 and ASME B16.34 standard.

2、The valve stem is tempered and nitrided, with high temperature resistance, wear resistance and good corrosion resistance.

3、Anti-scouring valve seat, valve flap, anti-scouring set, all through nitriding treatment, has the performance of scouring resistance, for the history of exchangeable parts.

4、Medium flow direction adopts high inlet and low outlet, which has the characteristics of small opening and closing torque and convenient opening.

5, the valve seat, the valve carp sealing surface using cobalt-based carbide surfacing or plasma spray welding and become, high-temperature wear-resistant, anti-scratch performance.

6、Valve body adopts forging structure.
