General Description:

Leakage from the valve gland (stem packing) is often a problem for environmental protection & sometime it is quite dangerous if such leakage is from a hazardous fluid or gas. STAVAL bellow sealed valves are designed with a bellow cartridge which welded to the valve bonnet and stem, so that when the stem up & down movement makes the bellows expands & compress. Therefore there is no sliding or rotating seals through which process fluid can leak.

Design Feature:

The product is a solid wedge with an expansion seat ring and a graphite stem packing for secondary sealing, which can ensure zero stem discharge and trouble-free cycles of less than 5,000 times

Application:

Can be used in general industries, including oil refineries, petrochemical and solar power plants, to ensure the supply of hot oil and steam.
