 | | LKB Low Pressure Butterfly valve |
Application LKB Low Pressure is a sanitary manually operated butterfly valve for use in stainless steel pipe systems. Working principle LKB Low Pressure is operated by means of a handle. The handle mechanically locks the valve in its open or closed position. A disc closes against a rubber seal when the handle is at right angle to the pipeline. When the handle is turned 90° the disc is parallel to the product flow and the valve is fully open. Standard design The valve consists of two valve body halves, valve disc, bushes for the stem and seal ring. The valve is assembled by means of screws and nuts.
The handle is fitted onto the valve by means of a cap/block system and screw. Materials | Valve body: | Stainless steel AISI 304. | | Disc: | Stainless steel AISI 304. | | Handle: | Stainless steel AISI 304. | | Seal: | EPDM. | | Finish: | Semi bright. |
Size Connections LKB Low Pressure is available with the following connection combinations: - - ISO welding end - ISO welding end.
- - ISO clamp end - ISO clamp end.
