1: Q47Y-64P stainless steel high pressure hard seal flange forged steel ball valve:
That is, the material is forged, and the density of the material is much higher than that of casting. The forged steel ball valve closing piece is a ball valve in which the ball rotates around the center line of the valve body to open and close. The seal is embedded in the stainless steel valve seat. There is a spring at the end of the metal valve seat. When the sealing surface is worn or burned, the spring pushes the valve seat and the ball to form a metal seal. It has a unique automatic pressure relief function. When the medium pressure in the middle cavity of the valve exceeds the spring pre-tightening force, the outlet end valve seat retreats away from the ball to achieve an automatic pressure relief effect. After pressure relief, the valve seat automatically resets. It is suitable for water, solvents, and acids. and natural gas and other general working media, and is also suitable for media with harsh working conditions, such as oxygen, hydrogen, methane and ethylene, etc., and is widely used in various industries.
2: Q47Y-64P stainless steel high pressure hard seal flange forged steel ball valve:
The standard valve seat adopts a spring structure, which pushes the valve seat towards the ball, ensuring good inlet and outlet two-way sealing performance; using the built-in discharge valve, the middle cavity of the valve body can be discharged outward; the pivot adopts an anti-blowout protection structure. Effectively prevent leakage; low friction coefficient bearings reduce torque to a minimum and facilitate valve opening and closing;
The valve stem is in perfect contact with the valve body, making the anti-static grounding device superior in performance.
It has the advantages of excellent performance, high reliability, wide range of uses and reasonable price.
3.Q47Y-64P stainless steel high pressure hard seal flange forged steel ball valve:
The valve body is divided into three parts along the cross-section perpendicular to the axis of the valve channel at the two valve seats. The entire valve is symmetrical along the central axis of the valve stem. High-pressure forged steel ball valves are mainly used on pipelines to cut, distribute and change the flow of media. direction. Its large pivot structure ensures accurate ball center position under high pressure, ensuring the valve's good operating performance.

The heavy hammer type hydraulically controlled slow-closing check butterfly valve adopts a heavy hammer type closing valve, so it is named the heavy hammer butterfly valve. It is mostly used at the outlet of circulating water pumps and the inlet of hydraulic turbines. Kaihang Automation Technology Co., Ltd. is a professional manufacturer of hydraulically controlled butterfly valves. This product is a weight-type hydraulically controlled butterfly valve. The opening of the hydraulic-controlled butterfly valve is hydraulically driven with an oil pressure of 13-16MPa, which reduces the size of the relay. During the opening process, the weight is lifted at the same time, and the lifted weight is used to store energy. Close and cancel the accumulator tank. After opening, the lock is automatically put in. The hydraulic system automatically maintains pressure. The weight does not fall and the valve disc does not shake. No power oil source is required when closing, the locking pin is automatically released, and the machine is closed according to a predetermined program. It is simple and reliable, and greatly simplifies the hydraulic system. Using double eccentric/triple eccentric valve plate, the horizontally installed valve shaft is raised a certain distance on the center line of the pipeline, so that the water facing area of the lower half of the valve plate is larger than the upper half, and the dynamic hydraulic force can be used to help the valve close to reduce the The weight of the weight allows the hydraulic device, butterfly valve control cabinet, electrical automatic control box, relay, and control oil pipe to be compactly integrated with the valve with a simple structure and small size, without the need for additional configuration by the user. The valve can realize local control, remote control and linkage control, and can meet the requirements of unattended and few people on duty. It is an ideal new pipeline control equipment.
