Features:

Hard graphite with excellent self-lubrication and anti-corrosion properties is adopted to the seat and flexible graphite to the cushion seal

Hard graphite seats and the graphite packing ensure a wide operating temperature range from -29°C to 500°C

Gratite offers superior cost effectiveness in comparison to the metal seated valves

High resistance to thermal shock prevents the cracking caused by thermal shock seen in ceramics

With high conductivity, Gratite? has an anti?static function

Blowout-proof stem (ASME Class 600 optional)

A two-piece body construction makes maintenance easier

The product features a fire safe design

Easy actuator mounting

It can be used for both flow directions (ASME Class 600, DN50 to DN100 is unidirectional flow).

Gratite boasts outstanding sealing characteristics
