10 Inch Check Valve

Product Description

10 inch check valve also called as 10 inch non return valve or dn250 check valve, prevent backflow in piping systems, these mechanisms ensure that the valve closes when the flow of fluid through the pipe is reversed. To ensure unobstructed flow, the check valve can automatically close when the pressure is reduced. They exist in many industries and are used in mining, gas and water.

Pipe size, pressure rating, working pressure, flow rate, and medium gravity and temperature are usually considered when purchasing a check valve.

Types of 10 inch check valve

Swing Check Valves

Tilting Disk Check Valves

Wafer Check Valves

Disk Check Valves

Piston Check Valves

Ball Check Valves

Duo-Check Valves

Non-Slam Check Valves

Features

The check valve protects the mechanical components in the piping system as the reverse flow of the fluid ceases. A check valve prevents primary backflow in the event of a pipe rupture. The mechanism also reduces wasted energy consumption by preventing backflow to lower pressures. Check valves have excellent hydrodynamic properties. Lighter weight facilitates installation, transport and storage.

Application

The valve body structure of the straight-through lift check valve adopts the valve body of the globe valve, and the valve disc moves up and down along the line in the channel. Straight-through lift check valves can generally only be installed in horizontal pipelines, while vertical lift check valves are generally installed in vertical pipelines. The products are widely used in pipelines of various working conditions such as petroleum, chemical, pharmaceutical, and electric power industries.

Production Range

Our factory has a complete variety of valve body materials, and the gasket can be reasonably selected according to the actual working conditions or user requirements, and can be suitable for various pressure, temperature and medium working conditions. Check valves with different structural forms and connection forms can be designed and manufactured according to user requirements, and used for various equipment. This valve is suitable for one-way opening and closing on medium pipelines such as water, steam, and petroleum products with a working temperature of ≤350 °C.

What are the requirements for the selection of 10 inch check valve

1. In order to prevent the backflow of the medium, check valves should be installed on the equipment, devices and pipelines;

2. The check valve is generally suitable for clean medium, not suitable for medium containing solid particles and high viscosity;

3. Generally, horizontal lift check valves should be used on horizontal pipes with a nominal diameter of 50mm;

4. Straight-through lift check valve can only be installed in horizontal pipelines;

5. For the pump inlet pipeline, the bottom valve should be selected. The bottom valve is generally only installed on the vertical pipeline of the pump inlet, and the medium flows from bottom to top;
