1.5 Inch Check Valve

Product Introduction

What 1.5 inch check valve?

A 1.5 inch check valve is a mechanical device that allows liquids and gases to flow in only one direction, preventing the flow from being reversed. They are classified as one-way valves, which means they have two openings in the body, one for fluid to enter and one for fluid to leave. Fluid flow in the desired direction opens the valve, while backflow forces the valve to close.

The operating mechanism of the check valve is simple and automatically stops the flow of fluid in the wrong direction. XURI offers many types of check valves in various configurations, functional types, sizes and material structure.

What types of 1.5 inch check valve are there?

According to the structure, check valves can be divided into three types: lift check valves, swing check valves and butterfly check valves. Lift check valve can be divided into vertical and horizontal. The swing check valve is divided into three types: single-lobe, double-lobe and multi-lobe. The butterfly check valve is a straight-through type. The above types of check valves can be divided into three types: threaded connection, flange connection and welding. A check valve is a valve that automatically prevents the backflow of fluid. The disc of the check valve opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve disc will automatically close under the action of fluid pressure difference, gravity and other factors to prevent the fluid from flowing back.

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.

What are the requirements for the selection?

1. The corresponding size of the check valve should be determined, and the valve supplier must provide the data of the selected size, so that the valve size when the valve is fully opened at a given flow rate can be found;

2. For high and medium pressure check valves below DN50mm, vertical lift check valves and straight-through lift check valves should be selected;

3. For low pressure check valves below DN50mm, butterfly check valves, vertical lift check valves and diaphragm check valves should be selected;

4. For high and medium pressure check valves with DN greater than 50mm and less than 600mm, swing check valves should be used;

5. For medium and low pressure check valves with DN greater than 200mm and less than 1200mm, non-wear spherical check valves should be selected;

6. For low-pressure check valves with DN greater than 50mm and less than 2000mm, butterfly check valves and diaphragm check valves should be selected;

7. For pipelines that require less or no water hammer when closed, slow-closing swing check valves and slow-closing butterfly check valves should be used.
