What are the valves for municipal pipelines

Municipal piping as we often refer to it includes; municipal water piping, municipal sewer piping, municipal heat piping and so on. The valves needed on different pipelines are the same and different.

Municipal water pipeline valves are: soft seal butterfly valves, soft seal gate valves, check valves, filters, rubber soft joints and so on.

Municipal sewage pipeline valves are: hard seal butterfly valve, soft seal butterfly valve, knife gate valve, filter, sewage valve and so on.

Municipal heat pipeline valves are: ball valves, globe valves, hard seal gate valves, hard seal butterfly valves, check valves and so on.

Gate valve: can be divided into open rod, dark rod, manual, electric, motor-driven and other forms, gate valve has a small fluid resistance, open and close the force is small, and the medium can flow in either direction and so on. However, the structure is more complex, the gate valve sealing surface is easy to be water impurities or particulate matter wiped or deposited on the bottom of the valve body, the morning closed tight defects. Often open the gate valve will sometimes appear valve plate fall off phenomenon, so that the system loses the ability to control.

Shut-off valve: compared with the gate valve has a simple structure, good sealing performance, easy maintenance and other advantages, but the opening and closing force is slightly greater than the gate valve, the installation should pay attention to the valve body is marked with an arrow (water flow) direction, shall not be installed in reverse.

Butterfly valve: in the water supply pipeline plays a full open and close the role of a valve. Its opening and closing force is larger, but the valve body is smaller and lighter. Butterfly valve has many types, according to the driving method and divided into handle type, turbo worm drive type, electric type, pneumatic type and other types.

Check valve: also known as check valve, is a kind of valve that only allows the medium to flow in one direction, so it has strict directionality. Mainly used to prevent backflow of water on the pipeline. Commonly used check valves are butterfly, lift type and swing type.

Safety valve: to avoid the official website, appliances or airtight water tank overpressure damage. There are spring type and lever type.

Municipal construction is related to people's livelihood, municipal pipelines selected valves must stand the test, the quality must pass. Our company has obtained the international system ISO9001 certification certificate, international CE certification certificate, international WRAS certification certificate, international ACS certification certificate, Canada CRN certification certificate, high-tech enterprise certificate certificate; the company's products are mainly: butterfly valves (double eccentric flange butterfly valves, vertical plate flange butterfly valves, centerline butterfly valves, soft-seat butterfly valves, signaling butterfly valves, lug butterfly valves, telescopic butterfly valve, High-performance butterfly valve, ventilated butterfly valve, high-temperature butterfly valve, three eccentric metal hard seal butterfly valve, welded butterfly valve, threaded seagull butterfly valve, etc.), gate valves (resilient sealing gate valves, hard sealing gate valves, fire signaling gate valves, knife gate valves, butt-welding gate valves), check valves (clamped double-plate check valves, clamped veneer check valves, fully lined rubber check valves, slow-closing check valves, heavy hammer-type liquid-controlled check valve, accumulator tank-type liquid-controlled check valves, swing-opening (double-plate check valves, lift check valves, muffler check valves, etc.), ball valves (flange floating ball valves, flange fixed ball valves, fully welded ball valves, etc.), globe valves, hydraulic control valves, regulating valves, pressure-reducing valves, vacuum valves, other valves, and other valve series, such as the ten major categories, a total of more than 3,000 varieties of specifications.
