Clamping valves

Purpose and types of clamping valves

Pinch valves are a type of shut-off valves designed to control the flow of liquids, including for clean and polluted water, emulsions, sludge, pulp, as well as compressed air, gaseous media and powdery substances. Polymers, metals and alloys are used for the production of valves. A variety of designs and sizes allows you to select a clamping valve for various environments and operating conditions.

According to the type of connection, clamping valves are available:

• With flange according to DIN EN 1092-1;
• With flange according to ANSI B16.5/150lbs;
• With thread inside according to DIN EN ISO 228;
• With thread inside according to ANSI/ASME B1.20.1;
• With clamping mechanism according to DIN 32676;
• With ends for welding according to DIN 11850;
• With one end for welding according to ASTM A554;
• With a fitting according to DIN 11851.

According to the type of drive, mechanical and automatic valves are distinguished. The use of clamping valves in enterprises increases production efficiency and reduces the total number of production cycles due to rational flow control.

The principle of operation of clamping valves

The liquid clamping valve is a cylinder, on opposite sides of which there are discs with a hole for mounting to the pipe. Inside the cylindrical body there is a hose made of elastic material. The hose has a high sensitivity to rebound, due to which the flow is blocked. The design and properties of the hose provide an airtight closure for gases, liquids, and bulk media. The maximum operating pressure that the valve can shut off depends on its modification and ranges from 0.5 to 6 bar. Mechanical clamping valves are operated manually, automatically - using special actuators controlled by automation.

Scope of application of clamping valves

Valves are used as shut-off valves on main pipelines transporting a variety of media, including solids, granules, abrasive and aggressive. In construction, the devices are used in pipelines used for pumping mortars. In the energy sector - in the ash removal systems of power plants, on pipes transporting coal to the furnace, etc. In the oil and gas sector, clamp valves are installed on pipes leading to storage facilities, technical tanks, mud lines, flotation systems, etc. Valves are in demand at enterprises of the chemical, pulp and paper, food, pharmaceutical industries, in the production of paints and varnishes.
