Farpro Yuanda supplies check valves that help prevent reverse flow in water, kuasa, chemical and oil and gas pipelines. The range includes swing, lift, wafer, 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.

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.

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

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

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

Injap Semak Bola
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.

Silent Check Valves
A responsive closing arrangement helps reduce the abrupt closure associated with conventional check valves.
Aplikasi dan Penggunaan Injap Semak Paling Penting

Water Supply and Pumping
Check valves help protect pumps and water networks against reverse flow after shutdown.

Penjanaan Kuasa
Non-return valves serve cooling water, utility and other plant piping systems.

Pemprosesan Kimia
Check valves restrict backflow in process lines and branches, with wetted materials matched to the medium.

Minyak dan Gas
Non-return valves support directional flow in pipeline and facility piping.
