No stem leakage
The stem area is sealed double with a formed multi-ply bellows and gland packing, which completely prevent stem leakage of toxic fluids.
Saving manufacturing costs
No loss of the line fluid through stem area will increase your productivity.
Wide range of applications
With high corrosion resistant valve bodies made of austenitic stainless steel and leak-free stem design, valves are almighty to handle toxic or inflammable fluids, steam and heat transfer media, as well as vacuum service.
Easy maintenance
Gland retightening and packing replacement are not required, minimizing troublesome maintenance works.
Protection of the quality of line fluids
Fluids are not in direct contact with an atmosphere, and protected from the contamination caused by foreign objects.
Lower operation torque
Since gland retightening is not required, stem rotation is not disturbed with the load of gland packing. Thus valves can be operated with minimized torque.
Cautions
• Take appropriate preventive measures when freezing is expected.
• Protect valves from impact pressure, such as water hammer.
• DO NOT install valves where excessive vibration is expected.
• Take appropriate measures to protect bellows from highly viscous or solidifiable fluids.
