Industrijski povratni ventili

Dom » Industrijski povratni ventili

Farpro Yuanda isporučuje nepovratne ventile koji pomažu spriječiti obrnuti protok vode, vlast, kemijski te naftovodi i plinovodi. The range includes swing, lift, napolitanka, ball and silent check designs.

Check valves operate automatically as flow conditions change. Each design has a different opening and closing response, allowing the valve to suit the pipeline layout and the way the system operates.

Browse the designs below to compare their construction and operating principles. Swing and lift checks are familiar choices for industrial piping; wafer designs suit installations with limited space, while silent checks are used where closing response and pump noise deserve particular attention.

Automatic Reverse-Flow Protection

A check valve uses the flow of the medium to open its disc or closing element. As forward flow falls, the closing element returns to its seat to restrict flow in the opposite direction. Normal operation requires no external actuator.

Body shape, disc travel and the closing mechanism influence pressure loss and response. That is why a pump discharge line and a steady process line may call for different check valve designs.

swing nepovratni ventil

Zakretni povratni ventili

A hinged disc opens with forward flow and returns toward its seat as the flow subsides or reverses.

Podignite povratni ventil klipa wcb

Podignite povratne ventile

Forward flow lifts the disc away from its seat; the disc returns to close the passage when flow falls.

Vafer povratni ventil

Vafer povratni ventili

A compact body fits between mating flanges, saving space along the pipeline.

kuglasti povratni ventil wcb

Kuglasti povratni ventili

A ball moves away from its seat during forward flow and returns to close the passage against reverse flow.

Stop Check Valves

The stop mechanism adds manual shut-off capability to the automatic non-return function.

tihi povratni ventil

Silent Check Valves

A responsive closing arrangement helps reduce the abrupt closure associated with conventional check valves.
