Wafer ball valve for medium temperatures from -50 ° C to + 400 ° C with soft or metal seats

This model can be considered an evolution of the historic Penta Wafer construction models, designed to make the maintenance of this type of valve easier, especially when used on particularly dirty services.

STEM TIGHTNESS

The double spring system and tightening nuts (live loading) allows to provide the correct preload to the rod seals, to recover wear and expansion differentials between rod and body.

SEALS

High temperature resistant Grafoil ® gaskets are used.

STEM

The stems are 100% oversized compared to the expected torque at max. DP rating.

The use of the Split Body construction allows easier assembly and disassembly operations and avoids the likelihood of seizure of the threaded closing rings. The automatic discharge of overpressures in the valve body together with the bi-directional feature make the model technically performing.

WSS: floating ball flat body valve

WSJ: flat body floating ball valve with intergal heating jacket
