Products Details

The non-wear spherical check valve is a specially designed valve that is mainly used to prevent the backflow of media. This kind of valve uses rubber wrapped spherical valve disc, under the action of the medium, the valve disc can roll on the slide in the valve body to realize the valve opening and closing. The following are some of the main features and parameters of non-wear spherical check valves:

Working principle: The non-wear spherical check valve uses the rubber coated rolling ball as the valve disc, under the action of the medium flow, the valve disc rolls up and down on the integral slide in the valve body, so as to realize the valve opening or closing.

Sealing performance: This valve has good sealing performance, and the sound is small when it is closed, which can reduce the water shock wave and realize the silenced closing.

Flow and resistance: The valve is designed as a full flow channel, so the flow is large, the resistance is small, and the head loss is 50% less than that of the swing type.

Installation: Non-wear spherical check valves can be installed horizontally or vertically for a variety of installation requirements.

Applicable medium and temperature: suitable for cold water, hot water, industrial and domestic sewage pipe network system, medium temperature range is usually 0℃ to 80℃.

Technical parameters: For example, the non-wear spherical check valve of HQ44X model has a nominal pressure of 1.0MPa, a shell test pressure of 1.5MPa, a seal test pressure of 1.1MPa, and a working temperature of no more than 80℃.

Main component materials: The body and bonnet may be made of ductile iron, cast steel or stainless steel, while the disc (ball) is usually cast iron or carbon steel coated with rubber.

Sizes and connections: Non-wear spherical check valves are available in a variety of sizes and connections, such as nominal diameters DN50 to DN1000, flange connections, and meet a variety of standards.

Application scenario: Especially suitable for pump outlet to prevent the backflow of the medium, but also suitable for submersible drainage pump and other occasions.

This information provides a comprehensive overview of non-wear spherical check valves, demonstrating their design advantages and application range.
