The bellows globe valve, also known as the bellows sealed globe valve, is designed with automatic roll welding to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem. The internal structure of the bellows globe valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded to the valve stem to prevent process fluid...

The valve is used to open and close the pipeline, control the flow direction, adjust and control the parameters of the transmission medium (temperature, pressure and flow) of the pipeline accessories. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. The valve is a control component in the fluid conveying system, which has the functions of s...

Valve/Actuator Characteristics Resolution is the smallest change in the position of a control valve stem. This limits the ability of the control system to position the valve precisely to the desired position. If the adjustment increments are so large that the flow alternates between too high and too low, a lower resolution valve/actuator may oscillate continuously around the desired setting. Altho...

Globe valve, also known as cut-off valve, belongs to the forced sealing type valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface not to leak. It is one of the most widely used valves, it is popular because of the opening and closing process between the sealing surface of the friction is small, more durable, open height is not large, easy to m...

As an indispensable part of fluid control systems, the importance of gas valves is self-evident. Gas valves play a crucial role in fields such as chemical, petroleum, and natural gas transportation, as well as environmental protection, medicine, and food. They are responsible for controlling parameters such as gas flow, pressure, and flow to ensure the safe and efficient operation of the system. N...

01. Introduction to Control Valve A regulating valve is usually composed of an electric or pneumatic actuator and a valve body. There are two main types of straight stroke: straight single seat and straight double seat. The latter has the characteristics of high flow capacity, low imbalance force, and stable operation, so it is usually particularly suitable for situations with high flow rate, high...
