Structural characteristics & features of flanged butterfly valves
The basic knowledge and structural characteristics of flange butterfly valves: The flanged butterfly valve has introduced a self-sealing design concept, in which the connection between the disc and the valve shaft adopts a patented pull-out pin structure. The main features of the valve are reliable sealing, bi-directional sealing, and tight connection without loosening, so that […]
structures and differences of Non-rising stem(NRS) and rising stem(RS) gate valve
structures and differences of Non-rising stem(NRS) gate valve and rising stem(RS) gate valve RS gate valve structure picture, NRS gate valve structure picture RS gate valve and NRS gate valve are different from the transmission mode. RS gate valve is a handwheel that drives a nut to rotate in place, and the stem is linearly […]
Pneumatic ball valve principle, structure and working principle
Principle of Pneumatic Ball Valve|Structure, Principle of Pneumatic Ball Valve Pneumatic ball valve is a combination of pneumatic actuator and ball valve, instead of manual operation, not only saves a lot of manpower and material resources, but also can control multiple ball valves at the same time. The actuator work of the pneumatic ball valve […]
Working Principle of Pneumatic Globe Valve
Principle of Pneumatic Globe Valve, Working Principle of Pneumatic Globe Valve Working principle of pneumatic stop valve: Pneumatic shut-off valve is a valve that uses compressed air as the power source. It adopts remote control. The main control room manually or automatically triggers the action command to activate the inlet and exhaust solenoid valves to […]
Pneumatic ball valve installation instructions
Pneumatic ball valve installation instructions Before installing the pneumatic ball valve: 1. Ensure that the installation position of the pneumatic ball valve is that the pipeline is in a coaxial position. The two flanges on the pipeline should be kept parallel. Confirm that the pipeline can bear the weight of the pneumatic ball valve. 2. […]
Ventilation butterfly valve installation instructions
Ventilation butterfly valve installation | instructions for use Instructions for use of the ventilation butterfly valve: The structural design of the ventilation butterfly valve should be combined with the operating conditions of the valve. 1. Under the smelting conditions with high temperature and high dust content, the design of the ventilation butterfly valve can adopt […]
Types and classifications of ball valves
Types and classifications of ball valves A ball valve is a valve with a sphere as a closing part. It is mainly composed of a valve body, a valve seat, a sphere, a valve stem, and a handle (or other driving devices, such as electric actuators, pneumatic actuators or hydraulic actuators). The valve stem drives […]
Electric globe valve model coding method
Representation method of electric shut-off valve model in China. Globe valve is also called cut-off valve or stop valve. As a cut-off valve, the electric shut-off valve is the most widely used and one of the most important valves. It is not only suitable for medium and low pressure pipelines, but also for high pressure […]
V-type regulating ball valve
Working principle of pneumatic V-type regulating ball valve The ball core of the pneumatic V-shaped regulating ball valve is designed with a special V-shaped notch, which has a shearing effect on the valve seat. It is especially suitable for media containing fibers, small solid particles, slurry and other media. According to different structural methods, it […]
Pneumatic globe valve model preparation method
Pneumatic globe valve /cut-off valve model preparation method Pneumatic shut-off valve is used to open and close the pipeline medium by compressed air, and the action speed is relatively faster. Different materials and seals are selected, which can be applied to various pressure, temperature and medium conditions, and the seal is reliable and the performance […]
