A ball valve is an industrial valve that controls the on-off and regulation of pipeline media through the rotation of a perforated ball inside the valve body. The ball rotates 90 degrees around the center line of the valve body to achieve full opening and full closing. It is one of the most widely used cut-off valves in fluid control systems.

A check valve, also known as a one-way valve, is an automatic protective valve. It opens and closes automatically relying on the flow pressure of the medium without manual or external driving force. It is mainly used to prevent pipeline medium backflow, avoid equipment damage, pipe network pressure fluctuation and medium pollution caused by reverse flow, and ensure the one-way stable operation of the pipeline system.

Shangtie Valve Technology Co., Ltd. is located in "China pump valve town" Wenzhou Oubei, convenient transportation, is a set of designmanufacturing, sales, service professional valve manufacturers, the company mainly produces American siandard,GB standard: power stationvalve, gate valve, globe valve, check valve, ball valve, buterfly valve, water seal valve, vacuum valve and other products.

Pressure sealed valves are special industrial valves designed for high-pressure working conditions, adopting a unique structure that uses medium pressure to assist sealing. The higher the medium pressure, the tighter the sealing fit, which completely solves the leakage problem of valves under high-pressure environments. Different from conventional gasket-sealed valves, they are core special valves for high-pressure pipeline systems.

A gate valve is a commonly used straight-through cut-off valve. It controls pipeline on-off by the up-and-down lifting of the gate disc with a straight and unbent flow channel. It is only suitable for full opening or full closing of media rather than flow regulation, serving as a basic pressure-stabilizing and cut-off valve in pipeline systems.

A globe valve is a unidirectional throttling regulating valve. It changes the flow gap of the valve seat through the up-and-down lifting of the valve disc to realize pipeline medium on-off and precise flow regulation. With a broken-line flow channel and forced sealing feature, it is a dual-purpose valve widely used for regulation and cut-off in industrial pipelines.

A butterfly valve is a lightweight and compact flow control valve with a circular disc as its core component. The disc rotates 0°~90° around the valve stem to realize the opening, closing and flow regulation of pipeline media. With the advantages of thin structure, easy installation and high flow capacity, it is a general and energy-saving industrial valve.
