They are used as isolation valves in pipelines and should not be used as control or regulating valves. The operation of the gate valve is accomplished by turning the valve stem clockwise to close (CTC) or clockwise to open (CTO). When you turn the stem, t

Do not use the valve as a crowbar to open the flange, as this may cause damage to the flange area and/or damage to the O-ring seal.

In the shut-off valve, the flow of water is controlled by a movable mandrel, and the flow of water is restricted by lowering the mandrel to a fixed valve seat.

Good sealing performance improves the reliability of the system. The friction resistance is small, the opening and closing is forceful and flexible. It has a long service life and can be switched repeatedly. High pressure and high temperature resistance,

Gate valves serve to cut the medium flow in the piping system, widely used in the field of potable water, water supply and drainage, sewage disposal, irrigation, air conditioning, fire protection as well as chemical and energy industry.

A three-way ball valve is a three-way valve that allows fluid to flow to an alternative path to the hydraulic system. It allows fluid to enter and exit the valve through more than one port.

Because of their spherical shape, these valves are called shut-off valves, and an internal baffle separates the two halves of the valve body. The moving part of the shut-off valve is composed of the valve disc, the valve stem and the hand wheel.

The pressure-sealed gate valve is designed in accordance with API 600, suitable for high temperature and high pressure working conditions, and is widely used in nuclear power plants and thermal power plants. Compared with bolted bonnet joint valves, they

Push-in joints do not require solder, glue, unions or tools. Corrosion resistant to extend service life, designed for drinking water distribution and circulating heating applications.

For the product category of gate valve, we are a professional manufacturer from China, gate valve, flange gate valve supplier/factory, wholesale elastic sealing gate valve research and development and manufacturing of high-quality products, we have perfec

You can expect the service life of the shut-off valve to be approximately 10 to 25 years, with an average of 20 years. However, if they are not "exercise" once a year or two years, then when you really need to close the valve for a pipeline emer

The gate valve is a two-way sealed valve. The valve body-bonnet joint and packing chamber are sealed with non-asbestos gaskets and packing to ensure a long service life.

The valve is bidirectional and can be installed in any direction relative to the water flow. The valve will control the flow equally in either direction. In order to obtain the best valve control and stable performance, the inlet straight pipe section sho

Excellent double-sided sealing function, test zero leakage. Excellent double-sided sealing function, test zero leakage. Simple structure, small size, light weight, fast opening and closing, and fixed operation. Suitable for various medium working conditio

Generally, gate valves are used to completely close the fluid flow in the pipeline, or to provide the full flow in the pipeline when fully opened. Therefore, it can be used in a fully closed or fully open position.
