Carbon steel gate valve
Carbon steel gate valve is a kind of spring gate valve, with a through hole and an outlet through hole. The inner holes are connected, and there is a channel that allows water to flow from the inlet to the outlet of the disc through a one-way channel; When it is lifted by hand, it closes the channel.
Product introduction:
carbon gate valve is a comprehensive spring gate valve, which has a through hole and an outlet through hole. The inner holes are connected, and there is a channel that allows water to flow from the inlet to the outlet of the disc through a one-way channel; When it is lifted by hand, it closes the channel. Carbon steel gate valve is used for low to medium pressure control of liquid or gas gate. They are normally in open position and are designed to be maintenance free for a long time with minimum clearance between disc and seat.
Our steel gate is a valve made of high-quality carbon steel, which is used for heating and various heating systems for daily use. And gases, including HFCS and HCFCs. These safety valves also have an easy to read and easy to operate stem.
Carbon steel gate valves are the most common in pipeline applications and are used to regulate the flow of oil, gas or water. These valves usually consist of a gate leaf assembly and housing, which are straight through holes except for the setting of the diverter. The classic design consists of two or more sets of discs and or discs, which are sealed on one disc.
Product advantages:
carbon gate valve is one of the main valves used in oil and natural gas industry, pipeline engineering and other industrial water transportation facilities. The gate valve is an upper gate valve with two closed and open gate valve positions. The blocked flow door came into being. As early as when entering the filter, we indicated or added the use of special devices through the non sealing surface, our parts, rotating or rotating position, and found that the valve was opened or retreated to the closed or open position.
Carbon steel wheel brake is a kind of full gate or half gate valve, and its other side has an open movable disc, which is a fixed part. This product operation structure is usually a kind of hand brake and low flow occasions. For example, small urban hub operators can carry out another opening and closing hand, and another new type of power on the road.
Gate valve is usually a valve used to control the flow of fluid (fluid and gas) and slurry. The working principle of the gate valve is that the seal formed by it is matched when closing the pipeline and leaking. Gates are usually used against valves as they should not hesitate to be exposed to liquid or pressure for operation.
Product design:
the design of gate valve is to design the pipeline flow and maintain the pressure in or other flow systems. Their solid valve and tubular valve stems with screw face gates allow parallel seal pull-out forces to be provided. Open the gate through the gate while keeping the operating gate stationary. There are many accessories and stocks under the gate, and more main materials: carbon steel, stainless steel, operation and operation.
Carbon gate valves are designed to withstand high pressure, high temperature and chemical exposure. When the forged structure has a carbon steel disc with full radius, even in the case of carbon steel disc with low flow, it can have good sealing performance, and can have better sealing performance than the flat disc, and can provide additional protection than the flat disc cover structure, providing open, convenient opening and other protection.
