1. Adopting the special hot valve core for steam medium, so the effective working pressure of the system is maximized.

2. Back pressure assisted seat back technology to ensure 3% seat back pressure difference

3. The side stem design is  to ensure that when the valve body is heated, its expansion is released at the side stem.
