Ductile Iron Flexible Rubber Flap Check Valve

1) Description

This series of rubber plate check valve is mainly composed of valve body, valve plate, valve cover and other parts, mainly suitable for drainage and sewage system, mainly installed at the outlet of water pump, full diameter design, low opening pressure, small water loss, rubber soft seal, can effectively prevent the medium counter-current, protect the normal operation of the pump.

2) Features

1. Small and reasonable design of rubber disc check valve structure, streamline to make the flow through smoothly and quickly, no debris deposition, do not affect the efficiency of pipeline operation.

2. The rubber of this valve adopts the current advanced nitrile rubber, its performance is stable, oil resistance is high, not easy to wear.

3. The rubber disc is pressed on the valve at high temperature, which is resistant to scour, has good sealing performance and can be used for a long time.4. The valve is simple to install and basically needs no maintenance after use to reduce manpower input.

5. The check effect of this valve is very good, the disc is tightly fitted to ensure that the fluid is not back flow.

3) Execution standard:

Technical parameters:

Operating principle:

Rubber disc check valve is through the pressure of fluid flow to open and close the valve, through the control of the opening of the switch to achieve the control of fluid flow, in the pipeline system automatically work.Rubber disc check valve can only be used in the one-way flow of the fluid pipeline, with safe and reliable, stable work, simple and practical characteristics, for the pipeline system transport to provide a security guarantee

Main parts and material.

Application:

Water plant, secondary water supply, municipal pipe network, reservoir, garbage treatment plant, subway and other industries in municipal engineering;Petrochemical, steel plant, power plant, shipbuilding and paper-making, bio-pharmaceutical, etc
