The full name of OS&Y is Outside Screw and Yoke. OS&Y is the abbreviation of the outside screw and yoke rising stem gate valve. , which means that the valve stem of the valve is exposed, and the thread is separated from the bushing. This structure makes it convenient to observe the movement and lubrication…
The knife gate valve, also known as knife-type gate valve，the slurry valve, and mud valve, is a common type of valve. Due to its simple structure, good sealing performance, and low flow resistance, the knife gate valve is widely applied in pipeline systems for conveying various media. The knife gate valve is a high-pressure valve…
Non-rising stem resilient seated gate valves are suitable for pipelines and equipment carrying liquid and gas media, and are used to cut off and regulate the media. In a resilient seated gate valve, the movement direction of the resilient gate plate is perpendicular to the fluid direction. Therefore, the resilient seated gate plate can only…
The rising stem metal seated gate valve is a common type of valve, mainly used for full-open and full-closed operations, and cannot be used for regulation and throttling. Its opening and closing element is the gate plate, and the movement direction of the gate plate is perpendicular to the fluid direction. In the rising stem…
DN300 gate valve, as a common fluid control device, its weight is one of the important indicators that users focus on when making a purchase. The weight of a 12″ gate valve is affected by various factors such as material, structural design, pressure rating, and whether it has attachments. Based on market research and professional…
Electric gate valves are key components in the field of industrial automation. Based on their characteristics, they can be divided into two major categories: angular-stroke electric gate valves and linear motion electric gate valves. Electric gate valves are widely used to regulate the flow of media in pipelines for liquids, gases, and air systems. Usually…
Electric Actuated Gate Valve In simple words, an electric actuated gate valve is to control the gate valve with an electric actuator, so as to realize the opening and closing of the valve. It consists of two parts: the upper part is the electric actuator, and the lower part is the gate valve. The electric…
The carbon steel gate valve is within the gate valve scope, differing only in material. Its material is carbon steel, and the opening and closing part is the gate plate. The movement direction of the gate plate is perpendicular to the fluid direction. It can only be fully opened or fully closed, and cannot be…
The dimension of a 4 inch gate valve is normally DN100. The 4″ gate valve is a commonly used pipeline control device, featured with a compact structure and a light weight. It can be widely applied in fields such as water treatment, petrochemical industry, etc. When using it, it is necessary to select an appropriate…
The 3 inch gate valve is suitable for fluid control in small and medium-sized pipelines and is widely used in fields such as construction, chemical industry, petroleum, pharmacy, and food. Its characteristics of good sealing performance, low flow loss, and small operating torque enable the 3 inch gate valve to meet the requirements of various…
The 2 inch gate valve is a common pipeline control device, mainly used for regulating and controlling the flow of fluids. Sorted by materials there are serval types of common 2 inch gate valve in the market:
The wedge gate valve gets its name because its sealing surfaces form a certain angle with the vertical center line, that is, the two sealing surfaces are in a wedge shape. Generally speaking, the angles between the sealing surfaces and the vertical center line are 2°52’, 3°30’, 5°, 8° or 10°, etc. The wedge gate…
The pneumatic gate valve uses compressed air to drive the piston in the cylinder, and then drive the valve stem to realize the opening and closing of the valve. When the pneumatic gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the plate…
