Its material is forged steel as same as the valve body, which is more durable and allows to be opened and closed thousands of times without deformation.

The gland effectively protects the internal packing, thus preventing the medium from leaking out from the stem.

As a common packing material, flexible graphite is cheap, easy to replace and can bear high & low temperature.

Different materials can be selected according to working conditions.

The conical disc has good sealing performance. Its conical sealing surface is relatively less damaged by medium’s sediment. And it can be surfacing welding Stellite and etc.

The forged body has a smooth surface, high pressure resistance, excellent corrosion resistance, better plasticity and toughness than the cast body, and a longer service life.

The seat can be surfacing welding Stellite and etc.
