[Essential information]
Operation principle: the valve causes the deformation of the temperature dual metal gas according to the change of the temperature, thus driving the valve core to make the complex shift, opening and closing the valve seat hole, and achieving the resistance to steam emission.

[Valve features]
The heat sensitive element adopts imported material. It has high sensitivity and durability. Condensed water is always prepared before the valve, forming a water seal, without fresh steam leakage. Good exhaust performance, resistance to water hammer, and installation at any angle.
[Adaptive condition]
The valve is suitable for the steam main line and the superheated steam pipe line, and can automatically eliminate the discharge temperature of the condensed water, and the energy saving effect is good.
