ARI-STOBU Stop valve series
1)Better performance
Proven technology: Solid plug, stem, seat are made of stainless material. Stem with roll hardened thread and burnished.
Seal selection of high-tensile gland packing.
2)Working principles
When the valve is closed, anticlockwise rotation of the hand wheel lifts the pilot plug off the larger balancing plug.
This allows the medium to pass through the plug and equalizes the pressure of the medium under the plug. After the pressures have been equalized within the values stated in the table, the valve can be opened by turning the valve further with normal mamual force.
3)More choices
Providing straight Angle or Y-type design and flange butt welding threads connection.
