What is the role of the diversion hole of the stainless steel plate gate valve with diversion?
Stainless steel plate gate valve with flow guide is a slide valve with parallel gate. The closing member can be a single ram or a double ram with a distraction mechanism between them. The pressing force of the ram to the valve seat is controlled by the medium pressure acting on the floating ram or floating valve seat. If it is a double gate valve, the opening mechanism between the two gates can supplement this pressing force. It is a kind of slide valve whose closing piece is parallel gate. The closing member can be a single ram or a double ram with a distraction mechanism between them. The pressing force of the ram to the valve seat is controlled by the medium pressure acting on the floating ram or floating valve seat. If it is a double gate valve, the opening mechanism between the two gates can supplement this pressing force.
It is installed on the pipeline and can be piggy directly with the pig. Since the gate is sliding on the two valve seat surfaces, it can also be applied to the medium with suspended particles, and the sealing surface is actually automatically positioned. The valve seat sealing surface will not be damaged by thermal deformation of the valve body. Moreover, even if it is closed in a cold state, the thermal elongation of the valve stem will not overload the sealing surface. At the same time, when the gate valve is closed, the flat gate valve without the diversion hole does not require the closing position of the gate plate to have a higher accuracy, so the opening and closing position can be controlled by the stroke.
This series of valves has the characteristics of reliable sealing performance, small opening and closing torque, sulfur resistance and wear resistance, long service life, and can be cleaned by fur balls. It is suitable for opening and closing devices in pipeline systems with non-corrosive and corrosive media such as water, oil, natural gas, and steam, especially suitable for stone, oil, gas, long-distance pipelines and other fields.

The working principle of hydraulic balance valve
Hydraulic valve manufacturer# Hydraulic balance valve is a device used to control the speed of hydraulic cylinder movement in hydraulic system. Its working principle is as follows: The hydraulic balance valve consists of a movable spool and a constant pressure spring. There are two holes on the spool, which are connected with the two chambers of the hydraulic cylinder. When the hydraulic system applies pressure, the pressure will act on a hole in the spool, causing the spool to move in the opposite direction.

Common use and performance of imported valves to explain
Valves have different requirements according to their types and uses, mainly sealing, strength, regulation, circulation, opening and closing performance. In the process of selecting the valve, in addition to considering the basic parameters and performance, but also consider the performance of the valve. So what are the different valve performance characteristics?
