German PIMATIC valves PIMATIC models PIMATIC prices

PIMATIC valves are used to prevent backflow of the medium. They open automatically using the kinetic energy of the fluid itself and close automatically during reverse flow. They are commonly installed at pump outlets, steam trap outlets, and other locations where reverse fluid flow is not permitted. Check valves are classified into three types: swing check, lift check, and wafer check. For swing check valves, the fluid can only flow from left to right; they close automatically during reverse flow. For lift check valves, when the fluid flows from left to right, the valve disc lifts to form a passage; during reverse flow, the valve disc is pressed against the valve seat and closed. For wafer check valves, when the fluid flows from left to right, the valve disc opens to form a passage; during reverse flow, the valve disc is pressed against the valve seat and closed. Wafer check valves allow multi-position installation, have small volume, light weight, and compact structure.

PIMATIC valve industry applications

Ball valves are widely used in oil refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal engineering, steel, and other industries, occupying a pivotal position in the national economy. It has a rotating action of 90 degrees. The plug body is spherical, with a circular through-hole or passage along its axis. Ball valves are mainly used in pipelines for cutting off, distributing, and changing the flow direction of the medium. They require only a 90-degree rotation operation and very small torque to achieve tight shutoff. Ball valves are most suitable for use as on-off and cut-off valves, V type ball valve. In addition to paying attention to pipeline parameters for electric valves, special attention should be paid to their operating environmental conditions, as the electric actuator in an electric valve is an electromechanical device whose operating status is greatly affected by the environment. Under normal conditions, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments. [1]

Precautions for PIMATIC valve performance testing

1) When valves of a specific specification are manufactured in batches, an official agency should be commissioned to perform the following performance tests: (1) Opening and closing torque of the valve under working pressure conditions; (2) Detection of the flow resistance coefficient of the valve under pipeline water transmission conditions. 2) The following tests should be performed on valves before leaving the factory: (1) With the valve in the open position, the valve body shall withstand an internal pressure test at twice the valve's working pressure; (2) With the valve in the closed position, both sides shall separately withstand 11 times the valve's working pressure without leakage; however, for metal-sealed butterfly valves, the leakage value shall not exceed the relevant requirements.

PIMATIC valve installation instructions

Butterfly valves have a simple structure, small volume, and light weight. They consist of relatively few components; just a few key parts constitute the butterfly valve. Opening is very convenient; simply rotate the switch to ninety degrees. Butterfly valves provide excellent control over fluids, allowing flow rate to be increased or decreased at any time. Valves exhibit certain resistance when transporting any fluid, and the resistance of a butterfly valve mainly comes from itself, such as the thickness of the butterfly valve body. To reduce fluid resistance, one only needs to reduce its thickness. Elastic seals have the disadvantage of being limited by temperature. The application range of butterfly valves is also quite wide. If used for flow control, different types and valve body sizes need to be selected, as butterfly valves are inherently more suitable for larger nominal diameters during design. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but are also applied in cooling water systems of thermal power stations.
