The manual gate valve is operated by a simple handwheel to raise the valve stem and gate. When closed, the gate rests on a seat ring, both of which are specially treated to provide a reliable closure.

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

Gate valves and globe valves are the two most common types of valves in industrial applications. Both have made great contributions to any industrial service. They may look similar, but the functions of these valves are different.

Ball valves are widely used in petroleum and natural gas, chemical and petrochemical, food industry, water supply, water treatment, building construction, light industry, power generation, pharmaceuticals, biotechnology, laboratory equipment, marine and o

Gate valves are used in a variety of industrial applications, including oil and gas, pharmaceuticals, manufacturing, automobiles, and ships.

Our company can also provide customized valve services according to your requirements. Feel free to contact us for more information or to request a complete product category.

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.

The operation of the gate valve is to perform a clockwise closing (CTC) or clockwise opening (CTO) rotary movement of the valve stem. When the valve stem is operated, the gate moves up or down on the threaded part of the valve stem.

In the 19th century, due to the increasing use of gate valves in industrial operations, their intensive development moved forward rapidly. Over time, the materials involved in manufacturing have been improved and modified to suit different applications.

The gate valve is designed for fully open or fully closed service. They are installed in the pipeline as isolation valves and should not be used as control or regulating valves.

The stop valve is a linear motion valve, which can be used to start and stop and adjust the fluid flow. The stop valve is mainly used for throttling service and automatic control.

Compared with ball valves, gate valves require multiple turns to fully open. The valve is not suitable for throttling or control, because partial opening will cause damage to the gate and wear of the valve seat. In addition, some valve closures can cause

We produce cast iron wafer butterfly valves, with hand lever or worm gear Operator. Our Butterfly Valves are widely used in drinking water system, sewage system, fire-fighting system. Butterfly Valves can produce from size DN40 to DN2400.

This is the connection from the actuator to the valve, which provides the driving force. The stem of the actuator control valve can be smooth, and the stem of the manual control valve can be threaded.

Ball valve is a form of right-angle rotary valve, which uses a hollow, perforated and rotating ball to control it. It is open when the hole of the ball is aligned with the hole of the ball, and it is closed when it is rotated 90 degrees by the valve handl
