Swing Check Valve

Jinquan Valve is a high-tech enterprise integrating valve product research, production, sales, and service. As an H44H and H44Y type PN16 ~ PN250 swing check valves supplier, our customized swing check valves are suitable for pressures of 1.6 ~ 25MPa, working temperatures of -29 ~ +550 ℃, and are applicable to pipeline conditions in the petroleum, chemical, pharmaceutical, fertilizer, power industries, and other environments. Applicable media include water, oil, steam, acidic media, and so on. We have been operating in the valve manufacturing field for over twenty years. With our experience, we have won high praise from the market for our reasonable prices, high quality, and attentive service.

1. Automatic Opening and Closing: The swing check valve opens and closes automatically based on the force of the media flow. When the media flows in the specified direction, the valve disc is pushed open, and the valve opens. When the media stops flowing or backflows, the valve disc closes under its own weight or spring force, preventing backflow. No manual operation is required, achieving automatic control.
2. Reliable Sealing: The sealing surfaces of the valve disc and seat are typically made of welded iron-based alloy or Stellite cobalt-based hard alloy, which is wear-resistant, heat-resistant, corrosion-resistant, and has good scratch resistance. This ensures a long-term stable sealing effect and effectively prevents media leakage. 3. Unobstructed Flow Channel: The flow channel is rationally designed, resulting in low fluid resistance. The media can pass smoothly through the swing check valve, reducing pressure loss and energy consumption.
