Vesey:More than twenty series of butterfly valves, gate valves, ball valves, control valves, globe valves, check valves, diaphragm valves and various automatic control valves have been formed.
Products are implemented in accordance with ISO, API, ANSI, DIN, GB, HG and other quality standards system.

The butterfly Valve, also known as the flap valve, is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium means that the closing member (valve or disc) is a disc that rotates around the valve shaft to achieve opening and closing a kind of valve.

Globe valve, also known as shutoff valve, belongs to forced sealing valve, so when the valve closes, pressure must be exerted on the disc to force the sealing surface not to leak.

The Gate Valve is a shutter for opening and closing, and the Globe Valve is also called a shut-off valve. It is a forced-sealed valve. The Check Valve refers to a circular valve whose opening and closing member is operated by its own weight and medium pressure to block the reverse flow of the medium.

Check valve is a kind of valve whose opening and closing part is round valve clack and whose action is produced by its own weight and medium pressure to block medium backflow. It is a kind of automatic valve, and is also called as cut-off valve, one-way valve, return valve or isolating valve.

Ball Valve, the opening and closing member (sphere) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-ball valve has a strong shear force between the V-shaped core and the metal seat of the hard-facing alloy. It is especially suitable for fiber-containing, micro-solid particles, etc.

Diaphragm valves are globe valves that use diaphragms as opening and closing parts to close flow passages, cut off fluid, and separate the inner cavity of the valve body and the inner cavity of the valve cover. Diaphragm is made of elastic, corrosion-resistant and non-permeable materials such as rubber and plastics. Valve body is made of plastic, FRP, ceramic or metal lining material.

The Regulating Valve also known as control valves, in the field of industrial automation process control, by accepting the control signals output by the control unit, by means of power operation to change the final control elements of the process parameters such as medium flow, pressure, temperature, liquid level. It usually consists of an actuator and a valve.

Valves are pipeline accessories used to open and close pipelines, control flow direction, regulate and control the parameters of transport media (temperature, pressure and flow).

Actuator is an indispensable and important part of automatic control system. Its function is to accept the control signal sent by the controller and change the size of the controlled medium, so that the controlled variable can be maintained in the required value or within a certain range. Actuators can be divided into three categories: pneumatic, hydraulic and electric according to their energy forms.
