Shin Yi flap check valve – Taiwan distributed by Tiger steel, We specialize in supplying Shin Yi flap check valve, cast iron Shin Yi valve.
What is a Flap Check Valve?
The check valve is a type of valve used to protect against reverse flow, allowing flow only in one direction and preventing it from flowing in the opposite direction. The valve leaf is designed to tilt 45° so it closes very quickly, minimizing the impact of the flow. The valve operates fully automatically based on the flow force of the water flow. The valve is connected to the flange system on both sides.
The flap check valve is composed of two main components, the valve body and the valve leaf:
– Valve: cast from FCD450 spherical cast iron, both sides are coated with high-grade epoxy paint with a thickness of ≥300 μm
– Valve blade: round disc manufactured from FCD450 spherical cast iron, 100% covered with EPDM rubber, suitable for both clean water and wastewater environments
When there is no fluid flow through the valve, the lá valve under the action of its own weight should be held firmly in the “Closed” position. When flow occurs to the valve, under the action of flow, the valve leaf is pushed out of the closed position and allows flow to pass through the valve. When the flow stops, the valve blade counters the backflow pressure and its own weight returns to the closed position, preventing backflow of water in the direction of the valve inlet. Thus, the operation of the one-way valve is completely automatic under the action of the liquid flow.
– Operation automatic based on the force of water flow, opening and closing quickly because the valve leaf is designed to tilt 45°.
– Valves are manufactured from cast iron FCD450, EPDM rubber for high durability, anti-rust, safe for clean water.
– The valve is light in weight, compact in design, and takes up little space when installed.
Notes on installation:
The flap check valve is installed in a two-flange system so the following points should be noted when installing:
– Install the valve in the correct opening direction of the valve leaf.
