Ductile Iron Di Dual Plate Wafer Check Valve
Wafer end swing check valve is mainly composed of three parts: body, disc( stem), spring. The short closing stroke of disc and the spring force improve the closing effect, while also reduce the pressure surge and slamming noise.
The valve body passageway is designed in a wing-shaped streamline type, allowing the medium to flow through the passageway rapidly and steadily with no noise. It is opened or closed by the valve clack moving to-and-fro through the valve body guiding axle under the spring effect. It can be installed on horizontal and vertical pipelines.
PRODUCT DETAILSTo API594
Final inspection tests to API598.
1.The sealing valve is designed with multiple narrow bands, which greatly improves the reliability of the seal, achieves a complete seal, and realizes zero leakage.
2.The structural performance is safe and reliable, the anti-interference is strong, the closing speed is fast, and the head loss is small.
3.Short structure length, good rigidity and easy installation.
4.A wide range of materials for main parts can be selected, and a wide range of media used.
5.Bubbles tight sealing and there is no leakage under the pressure test.
6.Long service life. Withstood the test of tens of thousands opening/closing operations.
