Fire protection switch ball valve, stainless steel ball valve, FQS fire ball valve, price and model

Description :

　　Ball valve is a widely used valve equipment, which is widely used in various fields such as petroleum, chemical, power, metallurgy, and steel. Ball valves are mainly used on pipelines to cut off, distribute, and change the direction of medium flow. The opening and closing component of a ball valve is a sphere, which rotates 90 degrees around the axis of the valve shaft to achieve the purpose of opening and closing. The sealing of existing ball valves is achieved by squeezing the valve seat with a ball, but the material hardness of the existing valve seat is high and the rebound is poor. In order to achieve valve sealing, it is necessary to increase the valve interference fit, which results in high valve torque, increases the overall cost of the valve, and leads to a relatively short service life of the valve.

　　Shandong Dongyue Crane Fire Equipment Manufacturing Co., Ltd. produces specialized ball valves for various fire monitors, with specifications and models: FQS80A, FQS80B, FQS80C, FQS65. There are two specifications for the interface: 65 and 80. Among them, the FQS80 fire ball valve is divided into three models: A, B, and C according to the size of the flange interface. The flange base is generally circular; The number of flange threads can be customized according to customer requirements.

　　The FQS series fire protection ball valves produced by Shandong Dongyue Crane and Fire Equipment Manufacturing Co., Ltd. are made of carbon steel material, connected by flanges, and adopt a fixed ball valve structure. The channel is straight through, with a pressure range of 1.6 (Mpa) or less. The inlet diameter is 100 (mm) and the outlet diameter is 80 (mm).
