2.The size of the connecting flange is one to two sizes larger than that of an ordinary valve of the same specification, and the structural length is the same as that of an ordinary valve of the same specification.
3.Steam or other hot insulation medium can flow freely in the jacket to ensure that the viscous medium can flow smoothly through the valve.
