Swing check valves allow forward flow and close automatically as the flow subsides or reverses. 본체 내부, a hinged disc swings away from the seat to open the passage, then returns toward it to restrict backflow.
Farpro supplies cast iron, cast steel and stainless steel swing check valves, including the H44T, H44H and H44W series. The range below brings those constructions together so you can compare materials and installation details.
Swing Check Valve Range
스윙 체크 밸브 스테인레스 스틸 – API H44W
The H44W stainless steel swing check valve uses a hinged disc that opens with forward flow and closes to prevent
스윙 체크 밸브 주강 – ANSI API H44H
The H44H is a flanged cast steel swing check valve that opens with forward flow and closes as the flow
Choosing a Swing Check Valve for the Line
Swing check valves are widely used in water, utility and industrial process piping. The hinged mechanism is straightforward, but it still needs enough forward flow for stable disc movement. Sizing only by the pipe diameter can overlook how the valve will behave when the system runs at reduced flow.
At a pump discharge, closing response matters as well as normal operation. Pipe layout, pump shutdown and the rate at which flow changes can influence noise and pressure surges. A swing check valve should therefore be considered as part of the system, rather than as a universal answer to water hammer. Our guide to check valves on pump discharges discusses those operating conditions in more detail.
Compare the H44H cast steel model with the cast iron and stainless steel alternatives above. Where space or shutdown response leads to a different design, 우리의 웨이퍼 그리고 자동 체크 밸브 offer other arrangements to consider.
Replacing a Swing Check Valve
If the old valve is noisy, leaking or wearing quickly, another valve of the same size may not solve the underlying problem. Tell us what happens during operation, particularly at low flow or when the pump stops.
For a straightforward replacement, the model, body markings and installation dimensions help us identify a suitable option. We can then compare the available valves with your existing pipework.
