Piston Valves & Bellow Seal Valves

The UKL Piston Valve is a seat-less and gland-less valve. By virtue of its
design, it can replace conventional types of globe valves or any other
isolation valves, bringing distinct advantages. The piston valve works
on the principle of resilient rings in conjunction with a metallic
stainless-steel piston that moves vertically between the rings, giving
an effective and durable seal. UKL Bellow Seal Valves, in gate or globe versions, incorporate metallic
stainless-steel bellows which are flexible welded to the shaft, at the
lower end, and to the body-bonnet flange at the other, thus effectively
shutting off any leak / emission to the atmosphere.
