Regulating valve , also called control valve, is used to control the size of fluid. When the regulating part of the valve receives a regulating signal, the valve stem will automatically control the opening and closing of the valve according to the signal, thereby regulating the fluid flow rate and pressure; often used for heating , gas, petrochemical and other pipelines.
Stop valve , also known as stop valve, can completely seal off the valve seat outlet by applying pressure by rotating the valve stem, thereby preventing fluid flow; stop valves are commonly used in natural gas, liquefied gas, sulfuric acid and other corrosive gas and liquid pipelines.
The gate valve is like a gate. By rotating the valve stem, the gate plate is controlled to move vertically up and down to control the fluid. The sealing rings on both sides of the gate plate can completely seal the entire section. The gate valve can only be fully opened and fully closed, and cannot be used to regulate flow. Gate valves are mainly used as interception devices in tap water, sewage, ships and other pipelines.
The swing check valve relies on the pressure of the fluid to open the valve cover. When the pressure of the fluid in the valve inlet and outlet pipes is balanced, the valve cover can close by its own gravity to prevent the fluid from passing through. Its main function is to prevent the fluid from flowing back. Flow, belongs to the automatic valve category; mainly used in petroleum, chemical, pharmaceutical and other pipelines.
