It is inconvenient to open a valve in a well or behind technological equipment manually. For remote control, a ball valve with an electric drive or a pneumatic version is used. Both rotate the ball, but require different power supply and are operated in different ways...

A small fistula on a pipe can stop the operation of an entire section. Water leaks out, access is inconvenient, and replacing a section requires preparation. For local repairs, stainless steel repair clamps with an elastic gasket are used. To...

The drawing indicates a shut-off valve, the application says "valve", and the supplier offers several similar products. To select valves for a specific area, you need to check the structure, stem sealing, and permissible operating parameters....

Temperature changes cause the pipeline to constantly expand and contract, creating loads on its elements. To prevent these natural movements from leading to deformations, depressurization, or damage to equipment, bellows compensators are installed in the system....

A valve is a pipeline valve with a translational movement of the closing element along the spindle to the seat. In technical catalogs, such a design is often called a shut-off valve, and in English-language documentation - a globe valve...

A steam trap is an automatic valve that releases condensate and non-condensable gases, but must block the passage for the working steam. What is a steam trap and why is it needed? In a steam system, some of the steam...

Hydraulic accumulators and expansion tanks look similar, but they perform different functions. They have different requirements for the membrane, temperature, pressure, and contact with water. A hydraulic accumulator and a membrane tank are one and the same...

Sand, scale, rust and sealant residues damage pumps, clog heat exchangers and affect the operation of water meters. The first protective barrier is a mud filter, selected according to the parameters of the system. Mud filter: what is it for...

A compact rotary valve is often used in water supply, heating, ventilation and industrial facilities. It takes up little space and is easily automated, but it does not replace a gate valve in every system. What is...

Any sealed system with liquid or gas moving inside is potentially dangerous. Temperature increases, chemical reactions, or a banal failure of automation lead to voltage surges in the pipes. This is where the first...

Stable operation of an autonomous water supply system is impossible without a hydraulic accumulator. This device, also called a membrane tank, solves several important tasks at once. It maintains stable pressure in the pipeline, protects the pump from frequent...

Modern engineering infrastructure is impossible without precise dosing and rapid shut-off of flows of liquids and gases. If a few decades ago this work was performed manually using conventional valves, today the standard...
