Shut-off valves (taps, valves, gate valves) from the manufacturer in Moscow
Shut-off valves include valves, valves, gate valves, valves that provide hermetically sealed shut-off of the flow of the working medium in pipelines. Stainless steel products of aisi 304 and aisi 316 grades are most in demand. Their advantages include strength, corrosion resistance, durability.
ALFA-STAR offers stainless steel shut-off components in a wide range: stainless steel ball valves aisi 304 and aisi 316 of various designs, gate valves and closures, check valves and filters. You can buy from us stainless steel ball valves aisi 316 and aisi 304 welded, threaded and flanged. Among the models produced is a three-way L-shaped stainless steel ball valve aisi 304 (there is a version made of aisi 316 steel). AISI 304 ball valves are used to work in an environment of aggressive liquids and gases, as well as for the transportation of steam, water, petroleum products in such industries as oil and gas production, chemical, food and pharmaceutical industries, construction and housing and communal services. AISI 316 ball valves are even more resistant to aggressive environments and high and/or low temperatures. They are used in the chemical industry and oil refining, shipbuilding, automotive, etc.
The check valve in the pipeline is designed to block the reverse flow of the working medium. The ALFA-STAR company offers a stainless steel flanged "flapper" check valve and a valve of the traditional BP model.
Filters in the pipeline clean the working flow from foreign solid inclusions and protect the equipment from contamination and premature wear. Our company offers aisi 304 and aisi 316 stainless steel filter with threaded and flanged connection.
A disk shutter is a two-position device in which the flow of the working medium is blocked by a disk. The ALFA-STAR company offers a stainless steel disc shutter operating in wet and aggressive environments, characterized by high strength, long service life and ease of installation and operation.
In the valves, the locking element moves perpendicular to the flow of the working medium and, as it were, cuts it off. Our catalog presents stainless steel gate valve aisi 304 and aisi 316 with a working element disc (gate). Gate valves can be used with high viscosity working media. They are used in water and gas supply pipelines, oil pipelines, etc. They are distinguished by ease of installation and operation, strength and durability.
