This international standard provides for the requirements of the full diameter, thick wall and large stem diameter of the corrosion, erosion and other operating conditions of the refinery and related uses heavy duty series of bolted bonnet steel gate valves.
This international standard to the following requirements of the characteristics of the gate valve:
Bolt connection valve cover,
- upper thread and bracket,
Lift type valve stem,
Non lift type hand wheel,
Single gate or double disc,
Wedge type or parallel valve seat,
Metal sealing surface,
- Flanged or butt welding ends.
