Top Butterfly Valve Manufacturing Companies [List]

Double eccentric flaps (high performance butterfly valves or double-offset butterfly valves) - different materials are used for the seat and disk. DezurIK high-performance butterfly valves have been successfully used in extreme services, including high-temperature services, steam-controlled throttling, high-cycle industrial gas e., and more.

Shut-off valves, as a rule, replaced ball valves in many industries, especially for petroleum, due to lower cost and ease of installation, but pipelines containing butterfly valves can not be “looped” for cleaning.

Shipbuilding butterfly valves are often used in ships and shipbuilding, because they withstand salt water, fit in tight spaces and operate pneumatically under water.

Some valve manufacturers, especially those specializing in the handling of corrosive materials, put a stem seal on the inside of the valve so that no material treated by the valve can come into contact with the valve stem. The flow control element is a disk of approximately the same diameter as the inner diameter of the adjacent pipe, which rotates on either a vertical or horizontal axis. To understand it in a very simple way, we'll give you a fictional example: if your recent searches on the Internet were highly literary, we would show you advertising about tension books. Triple eccentric shut-off valve for oil and gas valve Seat Construction Break flow is achieved through the valve disc sealing against a seat that is on the inner diameter periphery of the valve body. If the shut-off valve is connected to a non-return valve or pump, hold enough space between them to ensure that the disc does not interfere with the adjacent equipment. Avoiding problems with butterfly valves Most problems with butterfly valves in the field are directly related to poor installation procedures. Industrial use In the pharmaceutical, chemical and food industries, a butterfly valve is used to disrupt the flow of products (solid, liquid, gasic) within the process. Unlike most valve types, when installed between flanges, the disk of the shut-off valve actually extends over the surface of the valve body at certain angles (for example, 30° or more). But when it is in rotation, the bags allow the storage of a defined amount of solids, which makes the valve suitable for dosing bulk materials by gravity. Butterfly valves are particularly suitable for handling large flows of liquid or gas at relatively low pressures and for handling sludge or liquids containing large quantities of suspended solids. valve orientation As a rule of thumb, butterfly valves are installed with the stem in a vertical position, with the actuator mounted vertically directly above it, but there are some applications where the stem should be horizontal.
